It's time to invigorate your workouts -- and you're more ready than you think, says fitness expert and Reebok master trainer Sara Haley, who designed this series to boost cardiovascular endurance and burn fat. Pair these cardio moves with either your upper body or lower body strengtheners (or both!), depending on your Week 3 daily schedule.
For this first move, stand with your weight on the balls of your feet, heels slightly lifted, knees softly bent. Take small hops, rotating your clenched hands by your hips as if jumping rope. (Action jump rope is optional.) Continue for 60 seconds.
