Harry Potter: The Workout

You've read Harry Potter and the Deathly Hallows, the final (stifled sob) volume of the boy-witch epic. Now what do you do with the 784-page tome? Use it as a 5-pound weight! Here, a total-body workout from Keli Roberts, a certified trainer at Equinox in Pasadena, California.

For Legs and Butt: Stand with feet hip-width apart, holding the book in front of thighs, arms straight down. Squat and set the book on the floor. Stand up. Squat down again and pick up the book up with both hands. Repeat 20 times.

For Triceps: Lie on your back with knees bent, feet hip-width apart and on the floor. Hold the book in both hands with arms extended above your chest. Keeping elbows stationary, lower the book toward your head; straighten. Repeat 15 times.

For Core: Sit in a chair with knees hip-width apart, holding the book close to the chest with elbows bent. Twist your torso to the right while turning your knees to the left; twist going the other way. Do 20 reps.
