2. Is the use of bulking then cutting really neccessary? It seems to me as a technique used by professional bodybuilders (who probably still do a fair bit of aerobic activity anyway during bulking) or people who can't be bothered doing aerobic activity throughout the entire year and so go mad on "cutting" when the summer months roll around. I understand that you have to increase your calorie intake in order to gain mass but does this mean that you have to put on fat in the process? Is not keeping the protein intake high and the fat intake low aswell as maintaining both aerobic and anaerobic activities at the same time enough to both increase muscle mass and keep a low body fat level?
Is it true that aerobic exercise will hinder your efforts to increase muscle mass or is it just a myth?
