Do squats and deadlifts increase testosterone production?
I suspect it’s much simpler. If you do exercises, with really heavy weights, that stress the entire body, then the entire body grows to adapt to that stress. You can do isolation/concentration movements ’til you’re blue in the face, but once you place a bar on your back (with some really heavy weight on it) and squat down using every muscle in your body to support that weight, then your body has a serious stress to adapt to. RR I’m going to back this statement. This is the main reason any power lifter does overloads. My PR in the squat is 525, so I put 600 on the bar and simply hold it. In laymen’s term’s it’s simply getting used to the weight. That is my advice for powerlifters. For any other athlete, this advice may be different. Train for what you do! Not for what increases limit strength. Frederick C.
