Kathy Smith provides four workouts for a lean, sculpted, strong body. These workouts are broken out into four 15-minute sessions: upper body, buns & thighs, core, and fat burning. So with the warm up, each workout takes just about twenty minutes per day. Two, three, or four sessions can be combined to really bump up the intensity, burn more calories, and get the heart and lungs really pumping.
