I am trying to build mass. I read cardio and lifting should be as far apart from each other as possible, i.e. a 4 hour minimum, is that true? Would any of you recommendd doing cardio 2X a week on off days? What about cutting out cardio all together? Do any of you recommend doing cardio then replacing the calories lost so you can still build but still obtain the cardiovascular benefits? Also, what about doing cardio before or after workout? My schedule of time SUCKS ASS and approximatly 12-14 hours of my day is dedicated to wroking and commuting. Help please. :icon_idea
