Cardio Split
The Firm Cardio Split combines aerobics and weight training to deliver 3 times the fat loss of aerobics alone. Called Interval Training, this workout produces an "up-down-up-down: heart-rate pattern, proven to deliver far more fat loss than steady state aerobics (with constant heart rate).
Cardio Split has two parts - Lower Body with cardio and Upper Body with Cardio. Perform the parts back to back for 51 minute total body workout, or perform half the workout each day alternating lower and upper workouts on alternate days.
