A NASM-CPT (National Academy of Sports Medicine-certified personal trainer) trainer said that the training for the bodybuilding should consist of both muscle building period and max strength developing period. In this way, one can enhance the strength and build muscle efficiently. For example, one can use 60 Kg for the barbell bench press. To enhance the strength, one should adapt the max strength training for 8-12 weeks; then, he/she could use more weight (e.g. 70 kg) for the bench press.
I wonder whether this is true or not? Is this the only standard way for the body building training in the gym?
If one only wants to have a better body-shape/body-building; not the powerlifting performance, and only adapts muscle building training; without the max strength developing period, can he/she enhance more strength for the exercise efficiently and gain good body building result?
Would anyone please give me some explanations?
