ROAR – by Dr. Stacy Sims

Most people know that testosterone boosts athletic performance in some ways (e.g. muscle mass, heart strength).

Most people don’t know that estrogen boosts athletic performance in other ways (e.g. energy metabolism, flexibility, muscle fiber stamina, recovery).

Dr. Sims dives into great detail discussing these differences and many more, and how we as women can get the most out of our estrogen-enriched metabolism, estrogen-guided body composition, and take advantage of the fact that estrogen is, gram for gram, hundreds of times more powerful than testosterone (this is why serum estrogen is usually measured in picograms per milliliter or picomols per liter, while testosterone is usually measured in nanograms per milliliter or nanomols per liter; T is nearly 1,000x less effective than E, so greater quantities are needed). And that’s before metabolism-boosting progesterone joins the party!

She advises about exercise, nutrition, and taking care of all the body’s systems with the context of our estrogenic physiology in mind throughout (something that’s often an afterthought in most exercise books, if it even gets any attention at all), and biohacking with HRT and more. She also shares recipes! But not many; this is mostly not a recipe book.

The style is middle-range pop-science, with various facts, statistics, charts, and the like peppered throughout. On which note, there are no citations while reading, but there is a bibliography at the back, arranged on a chapter-by-chapter basis.

Bottom line: if you have female hormones and would like to be stronger, fitter, faster, and so forth, then this book can be a great guide!
