Infomercials are right about one thing: Exercise gear can transform your workout -- and your body. But unlike the products you see peddled on late-night television, medicine balls never goes out of style. One of our favorite med-ball moves: the high-knee lift. "The explosive exercise improves your coordination because it requires total-body balance and mobility," says David Jack, C.S.C.S., owner of ActivPrayer in Phoenix, Arizona and creator of 30 Days to Ripped. See, when you're moving at top speed, you need body control. This drill forces you to keep your core stable and your hips level, key factors in changing directions at any moment and staying upright when you should have fallen. Add it to your routine for a better-performing, more athletic-looking body.
