Before you really get started with muscle building, you need to recognize which of these two groups you’re in. Are you building muscle because you want to look like Arnold Schwarzenegger or because you’re going for more of a runner’s lean build? Once you’ve identified your personal goal with muscle building, you’ll know exactly what approach to take.
When it comes to muscle-building, how often you train and how often you rest are just as important as what you do when training and exercising. This is because the actually muscle-building part of the process happens not in the gym, but when you’re resting. During exercise, muscles are strained and slightly torn. During recovery, they are rebuilt to be bigger and stronger than before.
