During a tough leg workout, testosterone levels spike temporarily, but they go back to normal by the next day and don’t stay high.

Even after a super hard workout, the body’s baseline testosterone level doesn’t stay high the next day — it goes back to normal quickly.

When you lift weights and rest only 1 minute between sets, your body releases more stress and sex hormones right after the workout — but only at the very start; after a few weeks, this effect goes away.

Taking a specific supplement called HMB-FA before a tough workout doesn’t change your hormone levels or inflammation markers the next day, at least not in guys who regularly lift weights.

76%

Even if you lift heavy or light weights for 12 weeks, your body’s short-term hormone spike after each workout doesn’t change—and that means those hormone surges probably aren’t why your muscles get bigger or stronger over time.
