Every other day focus on your cardiovascular exercises
with bringing your heartrate up by jogging in place or knee
lifts, jumping jacks, and other aerobic movements. On the opposite days, focus on strength training by targeting the stomach with crunches and sit ups, the thighs can be targeted by lunges, squats, and leg lifts. Repititions are key to each of these types of exercise. When you feel the burn, you're doing good!
