Believe it or not, Louie’s first official Westside Barbell member was a bodybuilder named Jimmy Sitzer, (Bandbell Bar) an advocate of power-building utilizing our system. Today’s workouts are given a modern twist based on old school fundamentals. Be prepared to work hard. These workouts were designed specifically to induce muscular hypertrophy. Muscular hypertrophy involves an increase in size of skeletal muscle through growth of component cells. The workouts are set up by body part or muscular group – not by exercise. To induce the adaptation of hypertrophy, it is critical to focus on optimally loading, stimulating and fatiguing muscular groups; thus, we are not as concerned with overall movements (like in powerlifting).
