Sleep Is the Anabolic Lever Lifters Ignore

Summary

Gym culture obsesses over food and training intensity and treats sleep as optional — but sleep is where adaptation actually happens: poor sleep drops testosterone, makes you burn muscle instead of fat while dieting, and roughly doubles injury risk. As a rough sense of *how much it matters*, the gap between good and bad sleep is the kind of difference people associate with being "on" something — **not the same mechanism, but a comparable swing in your results**, and it's free.
