I hear a lot of advocacy of squats as a method for producing testosterone and human growth hormone as part of exercise-induced muscle hypertrophy.
I cannot, however, find any academic research on this question outside of anecdotal evidence. Is there any research to suggest that squats are the most effective exercise at producing hGH and testosterone? What other exercises do this?
**Note, I am not skeptical of the claim that the total work done during a particular exercise is related to hGH output-- I am skeptical of the claim that squats are significantly MORE effective than other exercises at inducing higher postexercise hGH blood levels. I am wondering if there is evidence explicating the degree to which certain compound exercises contribute to blood-serum hGH levels.
