Body For Life
The three-times-a-week weightlifting program in Body for Life is deceptively simple. If you've spent any time in the gym, you've already done all the exercises. But Phillips includes a couple of high-intensity sets at the end of each exercise that should compound the training effect on each muscle group. Same goes for the cardiovascular exercise he recommends: just 20 minutes, three times a week. But those 20 minutes are spent jacking the intensity up and down, accomplishing more in less time.
