′ To shape and develop the body it is necessary to do a lot of endurance training, that is the appropriate number of sets and reps. But I also believe that, unless you include low volume strength training, you will never achieve the hardness and density neccessary to create a first class physique ′
′ Muscle size and density created by a program that includes heavy training are easier to maintain for long periodsof time, even with a minimum of maintenance training. With high volume training only, much of the growth is the result of transient factors such as fluid retention and glycogen storage, BUT MUSCLE AS HARD AS A GRANITE WALL through power training comes as a result of an actual increase in muscle fiber size. Also as Franco tells me the muscle cell walls themselves grow thicker and tougher so tend to resist shrinking ′
