The Science Of How To Optimize Testosterone & ESTROGEN | Andrew Huberman

There are several studies exploring whether or not endurance activity can increase or decrease androgen levels and if combining endurance activity and weight training has any effect as well. Also, studies have been completed to see if doing the endurance activity first or second has an effect on androgen levels. The takeaway from these studies was that endurance activity, if performed first, leads to decreases in testosterone during the weight training session. As compared to the same weight training session done first, followed by the same endurance activity. So if you want to optimize increased testosterone levels, it seems to be the case that weight training first and doing cardio-type endurance activity afterward is the right order of business.
