14 Natural Energy Boosters

Need to clean that top shelf? Leave your stool where it is and carefully balance on your tiptoes, working your calves as you lengthen through your legs, says Sara Haley, a personal trainer and Reebok Global Instructor. Turn picking up the floor into an opportunity to do push-ups. "Every chance you get, lift your knees up off the floor so that you look like you're about to get into a push-up position," she says. Then hold it. Want a bigger challenge? See if you can scrub with one hand while staying in position. Even if this "kitchen" workout simply makes you laugh, you'll feel more energized from taking a break.
