Fitness professional Kathy Kaehler created a boot-camp-style workout for Drew Barrymore to help her get red carpet ready. You can find the complete workout in Kathy's new book, Kathy Kaehler's Celebrity Workouts. But we've got a few of her star moves right here. Use them at home, and you'll be fitter, stronger and ready for your close-up!

Crab Walk: You'll need about 20 to 30 feet of floor space for this drill. A long hallway is an ideal place to do it. Sit on the floor with your knees bent, feet flat on the floor, hands on the floor behind you, fingers pointing toward you. Lift your buttocks off the floor, using your hands and feet for support. Crab walk backward as fast as you can, keeping your butt lifted and your belly button pulled in, for 20 counts (1 count equals each time you move a hand). Turn around and return to starting position. Targets shoulders, triceps, buttocks, quadriceps, hamstrings, core muscles.

Kick-the-Tape Kickboxing: Take a piece of masking tape and put it on the wall at about waist level (stand with your side facing the wall). With your left leg slightly bent and your belly button pulled in, exhale as you kick your right leg directly to the side, leading with your right hip. Your right kneecap faces forward and your upper body leans slightly to the left as you kick. Watch your right foot to see how high you kick. Repeat the move, trying to kick your right foot on or above the tape each time. Start by doing 8 kicks with each leg, and gradually work up to 12. Targets inner and outer thighs, core muscles.
