Your body starts producing excess cortisol, the stress hormone, after 60 minutes of a workout session. Cortisol may block testosterone, which hurts all your efforts that you have been putting in towards achieving more muscle mass. Restricting workouts to 60 minutes or less helps you get more out of each workout. http://www.myhealthreviews.org/hd-testo-review-is-it-a-scam-or-legit/
