I want to take this opportunity to make a point about training. These guys, like most gymnasts, don't do much weight training. But they train for several hours every day. Mostly, they work with bodyweight.
There is a common misconception that if we train every day, we will become over-trained -- which is true if we are trying to push maximal weights everyday. But these guys (and girls) are proof that frequent training, if the intensity and volume are managed correctly, can produce amazingly strong and beautiful bodies.
I'm just saying.
