Re: how much cardio???
cardio, specifically high intensity cardio, is very important during muscle building. It replenishes the satellite cell pool (muscle stem cells that repair muscle cells). the main site of androgen receptors is satellite cells, so beyond the simple protein synthesis, satellite cells do the other part of the work of muscle repair.
