bodybuilders are stupid people, don't know shit about training. Once a week balls to walls, screaming and making stupid sound. Sore 4 days...
Smart people train a lot, but medium intensity and more frequent. All real athletes do like this. The reason u get sore and can't walk the day after is biz your not in shape (muscularvice). Torture your legs 3-4 times/week and after 3 moths u can kill them how much u want and never be sore...and they Will look better than ever.
Bodybuilders are the most stupid people out there. Just biz they don't know shit and they go for the bioscience shit. In all other sports people know how to train to achieve their goals. Lets say it again. Bodybuilders are stupid fuckers.
