Walking… Better.
We recently reviewed “52 Ways To Walk” by Annabel Streets. You asked us to share some more of our learnings from that book, and… Obviously we can’t do all 52, nor go into such detail, but here are three top tips inspired by that book…
Walk in the cold!
While cold weather is often seen as a reason to not walk, in fact, it has numerous health benefits, the most exciting of which might be:
Walking in the cold causes us to convert white and yellow fat into the healthier brown fat. If you didn’t know about this, neither did scientists until about 15 years ago.
In fact, scientists didn’t even know that adult humans could even have brown adipose tissue! It was really quite groundbreaking.
In case you missed it: The Changed Metabolic World with Human Brown Adipose Tissue: Therapeutic Visions
Work while you walk!
Obviously this is only appropriate for some kinds of work… but if in your life you have any kind of work that is chiefly thinking, a bunch of it can be done while walking.
Open your phone’s note-taking app, lock the screen and pocket your phone, and think on some problem that you need to solve. Whenever you have an “aha” moment, take out your phone and make a quick note on the go.
For that matter, if you have the money and space (or are fortunate to have an employer disposed towards facilitating such), you could even set up a treadmill desk… At worst, it wouldn’t harm your work (and it’ll be a LOT better than sitting for so long).
Walk within an hour of waking!
No, this doesn’t mean that if you don’t get out of the house within 60 minutes you say “Oh no, missed the window, guess it’s a day in today”
But it does mean: in the evening, make preparations to head out first thing in the morning. Set out your clothes and appropriate footwear, find your flask to fill with the beverage of your choice in the morning and set that with them.
Then, when morning arrives… do your morning necessaries (e.g. some manner of morning ablutions and perhaps a light breakfast), make that drink for your flask, and hit the road.
Why? We’ll tell you a secret:
You ever wondered why some people seem to be more able to keep a daylight-regulated circadian rhythm than others? It’s not just about smartphones and coffees…
This study found that getting sunlight (not electric light, not artificial sunlight, but actual sunlight, from the sun, even if filtered through partial cloud) between 08:30—09:00 resulted in higher levels of a protein called PER2. PER2 is critical for setting circadian rhythms, improving metabolism, and fortifying blood vessels.
Besides, on a more simplistic level, it’s also a wonderful and energizing start to a healthy and productive day!

What Is Making The Ringing In Your Ears Worse?
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Dr. Rachael Cook, an audiologist at Applied Hearing Solutions in Phoenix, Arizona, shares her professional insights into managing tinnitus.
If you’re unfamiliar with Tinnitus, it is an auditory condition characterized by a ringing, buzzing, or humming sound, and ffects nearly 10% of the population. We’ve written on Tinnitus, and how it can disrupt your life, in this article.
Key Triggers for Tinnitus
Several everyday habits can make your tinnitus louder. Caffeine and nicotine increase blood pressure, restricting blood flow to the cochlea and worsening tinnitus. Common medications, such as pain relievers, high-dose antibiotics, and antidepressants, can also exacerbate tinnitus, especially with higher or long-term dosages.
Impact of Diet and Sleep
Dietary choices significantly impact tinnitus. Alcohol and salt alter the fluid balance in the cochlea, increasing tinnitus perception. Alcohol changes blood flow patterns and neurotransmitter production, while high salt intake has similar effects. Poor sleep quality elevates stress levels, making it harder to ignore tinnitus signals. Addressing sleep disorders like sleep apnea and insomnia can help manage tinnitus symptoms.
Importance of Treating Hearing Loss
Untreated hearing loss worsens tinnitus. Nearly 90% of individuals with tinnitus have some hearing loss. Hearing aids can reduce tinnitus perception by restoring missing sounds and reducing the brain’s internal compensatory signals. Combining hearing aids with sound therapy is said to provide even greater relief.
Read more about hearing loss in our article on the topic.
Otherwise, for a great guide on managing tinnitus, we recommend watching Dr. Cook’s video:
Here’s hoping your ear’s aren’t ringing too much whilst watching the video!

When You “Can’t Complain”

A Bone To Pick… Up And Then Put Back Where We Found It
In today’s Psychology Sunday feature, we’re going to be flipping the narrative on gratitude, by tackling it from the other end.
We have, by the way, written previously about gratitude, and what mistakes to avoid, in one of our pieces on positive psychology:
How To Get Your Brain On A More Positive Track (Without Toxic Positivity)
“Can’t complain”
Your mission, should you choose to accept it (and come on, who doesn’t like a challenge?) is to go 21 days without complaining (to anyone, including yourself, about anything). If you break your streak, that’s ok, just start again!
Why?
Complaining is (unsurprisingly) inversely correlated with happiness, in a self-perpetuating cycle:
Pet Peeves and Happiness: How Do Happy People Complain?
And if a stronger motivation is required, there’s a considerable inverse correlation between all-cause happiness and all-cause mortality, even when potential confounding factors (e.g., chronic health conditions, socioeconomic status, etc) are controlled for, and especially as we get older:
Investing in Happiness: The Gerontological Perspective
How?
You may have already formulated some objections by this point, for example:
- Am I supposed to tell my doctor/therapist “I’m fine thanks; how are you?”
- Some things are worthy of complaint; should I be silent?
But both of these issues (communication, and righteousness) have answers:
On communication:
There is a difference between complaining, and giving the necessary information in answer to a question—or even volunteering such information.
For example, when our site went down yesterday, some of you wrote to us to let us know the links weren’t working. There is a substantive difference (semantic, ontological, and teleological) between:
- ❝The content was great but the links in “you may have missed” did not work.❞ ← a genuine piece of feedback we received (thank you!)
- ❝Wasted my time, couldn’t read your articles! Unsubscribing, and I hope your socks get wet tomorrow!❞ ← nobody said this; our subscribers are lovely (thank you)
- Note that the former wasn’t a complaint, it was genuinely helpful feedback, without which we might not have noticed the problem and fixed it.
- The latter was a complaint, and also (like many complaints) didn’t even address the actual problem usefully.
What makes it a complaint or not is not the information conveyed, but the tone and intention. So for example:
“You’ve only done half the job I asked you to!” → “Thank you for doing the first half of this job, could you please do the other half now?”
Writer’s anecdote: my washing machine needs a part replaced; the part was ordered two weeks ago and I was told it would take a week to arrive. It’s been two weeks, so tomorrow I will not complain, but I will politely ask whether they have any information about the delay, and a new estimated time of arrival. Because you know what? Whatever the delay is, complaining won’t make it arrive last week!
On righteousness:
Indeed, some things are very worthy of complaint. But are you able to effect a solution by complaining? If not, then it’s just hot air. And venting isn’t without its own merits (we touched on the benefits of emotional catharsis recently), but that should be a mindful choice when you choose to do that, not a matter of reactivity.
Complaining is a subset of criticizing, and criticizing can be done without the feeling and intent of complaining. However, it too should definitely be measured and considered, responsive, not reactive. This itself could be the topic for another main feature, but for now, here’s a Psychology Today article that at least explains the distinction in more words than we have room for here:
React vs Respond: What’s the difference?
This, by the way, also goes the same for engaging in social and political discourse. It’s easy to get angry and reactive, but it’s good to take a moment to pick your battles, and by all means fight for what you believe in, and/but also do so responsively rather than reactively.
Not only will your health thank you, but you’re also more likely to “win friends and influence people” and all that!
What gets measured, gets done
Find a way of tracking your streak. There are apps for that, like this one, or you could find a low-tech method you prefer.
Bonus tip: if you do mess up and complain, and you realize as you’re doing it, take a moment to take a breath and correct yourself in the moment.
Take care!

Polyphenol Paprika Pepper Penne
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
This one’s easier to promptly prepare than it is to pronounce unprepared! Ok, enough alliteration: this dish is as full of flavor as it is full of antioxidants, and it’s great for digestive health and heart health too.
You will need
- 4 large red bell peppers, diced
- 2 red onions, roughly chopped
- 1 bulb garlic, finely chopped
- 2 cups cherry tomatoes, halved
- 10oz wholemeal penne pasta
- 1 tbsp nutritional yeast
- 1 tbsp smoked paprika
- 1 tbsp black pepper
- Extra virgin olive oil for drizzling
Method
(we suggest you read everything at least once before doing anything)
1) Preheat the oven to 200℃ / 400℉ / Gas mark 6
2) Put the vegetables in a roasting tin; drizzle with oil, sprinkle with the seasonings (nooch, paprika, black pepper), stir well to mix and distribute the seasonings evenly, and roast for 20–25 minutes, stirring/turning occasionally. When the edges begin to caramelize, turn off the heat, but leave to keep warm.
3) Cook the penne al dente (this should take 7–8 minutes in boiling salted water). Rinse in cold water, then pass a kettle of hot water over them to reheat. This process removed starch and lowered the glycemic index, before reheating the pasta so that it’s hot to serve.
4) Place the roasted vegetables in a food processor and blitz for just a few seconds. You want to produce a very chunky sauce—but not just chunks or just sauce.
5) Combine the sauce and pasta to serve immediately.
Enjoy!

Driving under the influence of marijuana: An explainer and research roundup
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Update 1: On May 16, 2024, the U.S. Department of Justice sent a proposed rule to the Federal Register to downgrade marijuana from a Schedule I to a Schedule III drug. This is the first step in a lengthy approval process that starts with a 60-day comment period.
Update 2: Two recent research studies were added to the “Studies on marijuana and driving” section of this piece on July 18, 2024.
As marijuana use continues to rise and state-level marijuana legalization sweeps the U.S., researchers and policymakers are grappling with a growing public safety concern: marijuana-impaired driving.
As of April 2023, 38 U.S. states had legalized medical marijuana and 23 had legalized its recreational use, according to the National Conference of State Legislatures. Recreational or medical marijuana measures are on the ballot in seven states this year.
The issue of marijuana-impaired driving has not been an easy one to tackle because, unlike alcohol, which has well-established thresholds of impairment, the metrics for marijuana’s effects on driving remain rather elusive.
“We don’t have that kind of deep knowledge right now and it’s not because of lack of trying,” says Dr. Guohua Li, professor of epidemiology and the founding director of the Center for Injury Science and Prevention at Columbia University.
“Marijuana is very different from alcohol in important ways,” says Li, who has published several studies on marijuana and driving. “And one of them is that the effect of marijuana on cognitive functions and behaviors is much more unpredictable than alcohol. In general, alcohol is a depressant drug. But marijuana could act on the central nervous system as a depressant, a stimulant, and a hallucinogenic substance.”
Efforts to create a breathalyzer to measure the level of THC, the main psychoactive compound found in the marijuana plant, have largely failed, because “the THC molecule is much bigger than ethanol and its behavior after ingestion is very different from alcohol,” Li says.
Currently, the two most common methods used to measure THC concentration to identify impaired drivers are blood and saliva tests, although there’s ongoing debate about their reliability.
Marijuana, a term interchangeably used with cannabis, is the most commonly used federally illegal drug in the U.S.: 48.2 million people, or about 18% of Americans reported using it at least once in 2019, according to the latest available data from the Centers for Disease Control and Prevention. Worldwide, 2.5% of the population consumes marijuana, according to the World Health Organization.
Marijuana is legal in several countries, including Canada, where it was legalized in 2018. Despite state laws legalizing cannabis, it remains illegal at the federal level in the U.S.
As states grapple with the contentious issue of marijuana legalization, the debate is not just about public health, potential tax revenues and economic interests. At the heart of the discussion is also the U.S. criminal justice system.
Marijuana is shown to have medicinal qualities and, compared with substances like alcohol, tobacco, and opioids, it has relatively milder health risks. However, it’s not risk-free, a large body of research has shown.
Marijuana consumption can lead to immediate effects such as impaired muscle coordination and paranoia, as well as longer-term effects on mental health and cognitive functions — and addiction. As its use becomes more widespread, researchers are trying to better understand the potential hazards of marijuana, particularly for younger users whose brains are in critical stages of development.
Marijuana and driving
The use of marijuana among drivers, passengers and pedestrians has increased steadily over the past two decades, Li says.
Compared with the year 2000, the proportion of U.S. drivers on the road who are under the influence of marijuana has increased by several folds, between five to 10 times, based on toxicology testing of people who died in car crashes, Li says.
A 2022 report from the National Transportation Safety Board finds alcohol and cannabis are the two most commonly detected drugs among drivers arrested for impaired driving and fatally injured drivers. Most drivers who tested positive for cannabis also tested positive for another potentially impairing drug.
“Although cannabis and many other drugs have been shown to impair driving performance and are associated with increased crash risk, there is evidence that, relative to alcohol, awareness about the potential dangers of driving after using other drugs is lower,” according to the report.
Indeed, many U.S. adults perceive daily marijuana use or exposure to its smoke safer than tobacco, even though research finds otherwise.
Several studies have demonstrated marijuana’s impact on driving.
Marijuana use can reduce the drivers’ ability to pay attention, particularly when they are performing multiple tasks, research finds. It also slows reaction time and can impair coordination.
“The combination is that you potentially have people who are noticing hazards later, braking slower and potentially not even noticing hazards because of their inability to focus on competing things on the road,” says Dr. Daniel Myran, an assistant professor at the Department of Family Medicine and health services researcher at the University of Ottawa.
In a study published in September in JAMA Network Open, Myran and colleagues find that from 2010 to 2021 the rate of cannabis-involved traffic injuries that led to emergency department visits in Ontario, Canada, increased by 475%, from 0.18 per 1,000 traffic injury emergency department visits in 2010 to 1.01 visits in 2021.
To be sure, cannabis-involved traffic injuries made up a small fraction of all traffic injury-related visits to hospital emergency departments. Out of 947,604 traffic injury emergency department visits, 426 had documented cannabis involvement.
Myran cautions the increase shouldn’t be solely attributed to marijuana legalization. It captures changing societal attitudes toward marijuana and acceptance of cannabis use over time in the lead-up to legalization. In addition, it may reflect an increasing awareness among health care providers about cannabis-impaired driving, and they may be more likely to ask about cannabis use and document it in medical charts, he says.
“When you look at the 475% increase in cannabis involvement in traffic injuries, rather than saying legalizing cannabis has caused the roads to be unsafe and is a public health disaster, it’s that cannabis use appears to be growing as a risk for road traffic injuries and that there seem to be more cannabis impaired drivers on the road,” Myran says. “Legalization may have accelerated this trend. Faced with this increase, we need to think about what are public health measures and different policy interventions to reduce harms from cannabis-impaired driving.”
Setting a legal limit for marijuana-impaired driving
Setting a legal limit for marijuana-impaired driving has not been easy. Countries like Canada and some U.S. states have agreed upon a certain level of THC in blood, usually between 1 to 5 nanograms per milliliter. Still, some studies have found those limits to be weak indicators of cannabis-impaired driving.
When Canada legalized recreational marijuana in 2018, it also passed a law that made it illegal to drive with blood THC levels of more than 2 nanograms. The penalties are more severe for blood THC levels above 5 nanograms. The blood test is done at the police station for people who are pulled over and are deemed to be drug impaired.
In the U.S., five states — Ohio, Illinois, Montana, Washington and Nevada — have “per se laws,” which set a specific amount of THC in the driver’s blood as evidence of impaired driving, according to the National Conference of State Legislatures. That limit ranges between 2 and 5 nanograms of THC per milliliter of blood.
Colorado, meanwhile, has a “permissible inference law,” which states that it’s permissible to assume the driver was under the influence if their blood THC level is 5 nanograms per milliliter or higher, according to NCSL.
Twelve states, most which have legalized some form of marijuana of use, have zero tolerance laws for any amount of certain drugs, including THC, in the body.
The remaining states have “driving under the influence of drugs” laws. Among those states, Alabama and Michigan, have oral fluid roadside testing program to screen drivers for marijuana and other drugs, according to NCSL.
In May this year, the U.S. Department of Transportation published a final rule that allows employers to use saliva testing for commercially licensed drivers, including truck drivers. The rule, which went into effect in June, sets the THC limit in saliva at 4 nanograms.
Saliva tests can detect THC for 8 to 24 hours after use, but the tests are not perfect and can results in false positives, leading some scientists to argue against using them in randomly-selected drivers.
In a 2021 report, the U.S. National Institute of Justice, the research and development arm of the Department of Justice, concluded that THC levels in bodily fluids, including blood and saliva “were not reliable indicators of marijuana intoxication.”
Studies on marijuana and driving
Over the past two decades, many studies have shown marijuana use can impair driving. However, discussions about what’s the best way to measure the level of THC in blood or saliva are ongoing. Below, we highlight and summarize several recent studies that address the issue. The studies are listed in order of publication date. We also include a list of related studies and resources to inform your audiences.
State Driving Under the Influence of Drugs Laws
Alexandra N. Origenes, Sarah A. White, Emma E. McGinty and Jon S. Vernick. Journal of Law, Medicine & Ethics, July 2024.Summary: As of January 2023, 33 states and D.C. had a driving under the influence of drugs law for at least one drug other than cannabis. Of those, 29 states and D.C. had a law specifically for driving under the influence of cannabis, in addition to a law for driving under the influence of other drugs. Four states had a driving under the influence of drug laws, excluding cannabis. Meanwhile, 17 states had no law for driving under the influence of drugs, including cannabis. “The 17 states lacking a DUID law that names specific drugs should consider enacting such a law. These states already have expressed their concern — through legislation — with drug-impaired driving. However, failure to name specific drugs is likely to make the laws more difficult to enforce. These laws may force courts and/or law enforcement to rely on potentially subjective indicators of impairment,” the authors write.
Associations between Adolescent Marijuana Use, Driving After Marijuana Use and Recreational Retail Sale in Colorado, USA
Lucas M. Neuroth, et al. Substance Use & Misuse, October 2023.Summary: Researchers use data from four waves (2013, 2015, 2017 and 2019) of the Healthy Kids Colorado Survey, including 47,518 students 15 and older who indicated that they drove. They find 20.3% of students said that they had used marijuana in the past month and 10.5% said they had driven under the influence of marijuana. They find that the availability of recreational marijuana in stores was associated with an increased prevalence of using marijuana one to two times in the past month and driving under the influence of marijuana at least once. “Over the study period, one in ten high school age drivers engaged in [driving after marijuana use], which is concerning given the high risk of motor vehicle-related injury and death arising from impaired driving among adolescents,” the authors write.
Are Blood and Oral Fluid Δ9-tetrahydrocannabinol (THC) and Metabolite Concentrations Related to Impairment? A Meta-Regression Analysis
Danielle McCartney, et al. Neuroscience & Biobehavioral Reviews, March 2022.Summary: Commonly used THC measurements may not be strong indicators of driving impairment. While there is a relationship between certain biomarkers like blood THC concentrations and impaired driving, this correlation is often weak. The study underscores the need for more nuanced and comprehensive research on this topic, especially as cannabis usage becomes more widespread and legally accepted.
The Effects of Cannabis and Alcohol on Driving Performance and Driver Behaviour: A Systematic Review and Meta-Analysis
Sarah M. Simmons, Jeff K. Caird, Frances Sterzer and Mark Asbridge. Addiction, January 2022.Summary: This meta-analysis of experimental driving studies, including driving simulations, confirms that cannabis impairs driving performance, contrary to some beliefs that it might enhance driving abilities. Cannabis affects lateral control and speed — typically increasing lane excursions while reducing speed. The combination of alcohol and marijuana appears worse than either alone, challenging the idea that they cancel each other out.
Cannabis Legalization and Detection of Tetrahydrocannabinol in Injured Drivers
Jeffrey R. Brubacher, et al. The New England Journal of Medicine, January 2022.Summary: Following the legalization of recreational marijuana in Canada, there was a notable increase in injured drivers testing positive for THC, especially among those 50 years of age or older. This rise in cannabis-related driving incidents occurred even with new traffic laws aiming to deter cannabis-impaired driving. This uptick began before legalization became official, possibly due to perceptions that cannabis use was soon-to-be legal or illegal but not enforced. The data suggests that while legalization has broad societal impacts, more comprehensive strategies are needed to deter driving under the influence of cannabis and raise public awareness about its risks.
Cannabis and Driving
Godfrey D. Pearlson, Michael C. Stevens and Deepak Cyril D’Souza. Frontiers in Psychiatry, September 2021.Summary: Cannabis-impaired driving is a growing public health concern, and studies show that such drivers are more likely to be involved in car crashes, according to this review paper. Drivers are less affected by cannabis than they are by alcohol or cocaine, but the problem is expected to escalate with increasing cannabis legalization and use. Unlike alcohol, THC’s properties make it challenging to determine direct impairment levels from testing results. Current roadside tests lack precision in detecting genuine cannabis-impaired drivers, leading to potential wrongful convictions. Moreover, there is a pressing need for research on the combined effects of alcohol and cannabis on driving, as well as the impact of emerging popular forms of cannabis, like concentrates and edibles. The authors recommend public awareness campaigns about the dangers of driving under the influence of cannabis, similar to those against drunk driving, to address misconceptions. Policymakers should prioritize science-based decisions and encourage further research in this domain.
Demographic And Policy-Based Differences in Behaviors And Attitudes Towards Driving After Marijuana Use: An Analysis of the 2013–2017 Traffic Safety Culture Index
Marco H. Benedetti, et al. BMC Research Notes, June 2021.Summary: The study, based on a U.S. survey, finds younger, low-income, low-education and male participants were more tolerant of driving after marijuana consumption. Notably, those in states that legalized medical marijuana reported driving after use more frequently, aligning with studies indicating a higher prevalence of THC detection in drivers from these states. Overall, while the majority perceive driving after marijuana use as dangerous, not all research agrees on its impairment effects. Existing studies highlight that marijuana impacts motor skills and executive functions, yet its direct correlation with crash risk remains debated, given the variations in individual tolerance and how long THC remains in the system.
Driving Under the Influence of Cannabis: A Framework for Future Policy
Robert M. Chow, et al.Anesthesia & Analgesia, June 2019.Summary: The study presents a conceptual framework focusing on four main domains: legalization, driving under the influence of cannabis, driver impairment, and motor vehicle accidents. With the growing legalization of cannabis, there’s an anticipated rise in cannabis-impaired driving cases. The authors group marijuana users into infrequent users who show significant impairment with increased THC blood levels, chronic users with minimal impairment despite high THC levels, and those with consistent psychomotor deficits. Current challenges lie in the lack of standardized regulation for drivers influenced by cannabis, primarily because of state-to-state variability and the absence of a federal statutory limit for blood THC levels. European nations, however, have established thresholds for blood THC levels, ranging from 0.5 to 50.0 micrograms per liter depending on whether blood or blood serum are tested. The authors suggest the combined use of alcohol and THC blood tests with a psychomotor evaluation by a trained professional to determine impairment levels. The paper stresses the importance of creating a structured policy framework, given the rising acceptance and use of marijuana in society.

So, no question/request too big or small
❝Interesting about DVT after surgery. A friend recently got diagnosed with foot drop. Could you explain that? Thank you.❞
First, for reference, the article about DVT after surgery was:
DVT Risk Management Beyond The Socks
As for foot drop…
Foot drop is descriptive of the main symptom: the inability to raise the front part of the foot due to localized weakness/paralysis. Hence, if a person with foot drop dangles their feet over the edge of the bed, for example, the affected foot will simply flop down, while the other (if unaffected) can remain in place under its own power. The condition is usually neurological in origin, though there are various more specific causes:
When walking unassisted, this will typically result in a distinctive “steppage gait”, as it’s necessary to lift the foot higher to compensate, or else the toes will scuff along the ground.
There are mobility aids that can return one’s walking to more or less normal, like this example product on Amazon.
Incidentally, the above product will slightly shorten the lifespan of shoes, as it will necessarily pull a little at the front.
There are alternatives that won’t like this example product on Amazon, but this comes with the different problem that it limits the user to stepping flat-footedly, which is not only also not an ideal gait, but also, will serve to allow any muscles down there that were still (partially or fully) functional to atrophy. For this reason, we’d recommend the first product we mentioned over the second one, unless your personal physiotherapist or similar advises otherwise (because they know your situation and we don’t).
Both have their merits, though:

Of course, prevention is better than cure, so while some things are unavoidable (especially when it comes to neurological conditions), we can all look after our nerve health as well as possible along the way:

…which this writer personally takes daily and swears by (went from frequent pins-and-needles to no symptoms and have stayed that way, and that’s after many injuries over the years).

❝Any idea about the latest research on the most effective exercises for osteoporosis?❞
While there isn’t much new of late in this regard, there is plenty of research!
First, what you might want to avoid:
- Sit-ups, and other exercises with a lot of repeated spinal flexion
- Running, and other high-impact exercises
- Skiing, horse-riding, and other activities with a high risk of falling
- Golf and tennis (both disproportionately likely to result in injuries to wrists, elbows, and knees)
Next, what you might want to bear in mind:
While in principle resistance training is good for building strong bones, good form becomes all the more important if you have osteoporosis, so consider working with a trainer if you’re not 100% certain you know what you’re doing:
Some of the best exercises for osteoporosis are isometric exercises:
