Day 5: Shake Out to Burn Up Your Body
This workout includes two exercises per large muscle group—legs and back—and one exercise per small muscle group. Most people don’t like doing legs, so I put them first in this session. Exhaust your legs right from the start to fire up your metabolic furnace and make your entire workout harder. Right after you work on your legs, you’ve got a superset for back, and then you’ll finish with a series of exercises for the smaller muscle groups. At that point, there is no rest between exercises or supersets!
