Most might be surprise how much these short programs can increase strength and size. If their approached with serious intent and not just run through with lighter weight. Success can even come with as little a 4 to 6 sets per muscle group, while using compound exercises.
Common mistake most make, when gains are at a standstill ,is becoming desperate and adding more exercises, sets or training days. When they should take a week, or so off training, and begin to do short and to the point workouts. In this case, less is better. Good Luck.
