how to run and train for strength successfully over a long time, how much would you run for it not interfere with strength training?
scooby said it is only a myth that one lose muscle from cardio.
so as much running as one wants, just ovoid overtraining?
Train a 3 day split and do cardio 2-3 times a week. It also is a question of your body type/motivation. The myth that cardio is bad for bodybuilders is rubbish.
