I know that people who do heavy squats before trying their vertical jump can jump HIGHER than if they didnt do the heavy squats. BUt that is not really relevant lol
The correct way to stretch is to do DYNAMIC stretching before you lift, STATIC stretching after you lift. Dynamic stretching is still stretching the muscle but you are not holding it in one place for 20+ seconds.
I think you guys are both agreeing on this, static stretching is not good before working out. However, dynamic stretching can be beneficial. I think getting your blood pumping either by walking/jogging/warm up sets with lighter weights is good. Jigga, how does running shorten your hip flexors? Every time I do squats after a jog I feel way better and more loose.
