The smarter approach would be to establish this muscular foundation then incorporate the aerobic segments and vary the intensities of both the aerobic and the weight training until you reach the desired goal. Please keep in mind if you are not eating in accordance with that goal, it will not happen. This is not a good thing. And until exercise videos start to address what is truly necessary to be successful at body transformation, my opinion of them will remain low. It gained popularity after the 1992 Olympics in which several of the British athletes were using Creatine and benefited from its use.
Creatine actually helps the muscles retain more water molecules within the muscle cell.
In all likelihood, yes, it will help you to bulk. Yes, it will make you stronger. But if your eating plan is not your foundation, then the benefits you derive from any supplement, Creatine included, are greatly minimized. This is without using any supplements. And, in fact, there are no supplements on the market which can have as powerful an effect on the body as food.
