Level 1 Training
Muscle growth starts with quality training, so the base of the pyramid focuses on training variables linked to muscle-growth processes. These are the factors that allow you to construct an effective program and create the stimulus your body needs in order to change!
Favor free-weight, multijoint movements. Single-joint movements like leg extensions or cable cross-overs have their place, but they shouldn’t be the centerpiece of your mass-building routine. Multijoint movements (think bench and squat) recruit far more muscle mass and give your body a greater stimulus to grow. Moreover, the challenge of handling a free-weight version of an exercise improves anabolism over a machine.
Train at the right intensity. Exercise scientists have determined most people should train between 70-85 percent of their one-rep max to elicit an optimal hypertrophic response. Choose a weight that allows you to do 6-12 reps with good form before reaching failure.
