Is it a good idea to do really a lot of push-ups? I'm currently doing 70-80 in one series, but after long training I'm hoping to do much much more. Of course every exercise is good for muscles and helps to train endurance etc.
But wouldn't doing a really big number of push-ups (say, 1000 and more) have some side-effects? Wouldn't it be too much for the joints, for example? Or wouldn't the tendons in forearms be in danger?
I want to be strong and fit, but it first I don't want to hurt myself so I want to be cautious when it comes to intensive training.
