Forget expensive gym memberships, fancy equipment, and pricey workout clothes -- here's a home workout that won't cost you a dime. With equipment that nearly every home has (bathtub, kitchen chair, masking tape), it's both cheap and easy to assemble this home gym.

Not only that, this workout looks surprisingly efficient. Combining bursts of aerobic activity like stair climbing and jumping in place with muscle-building strength training moves, this 10-minute workout (20 if you do it twice) appears to have it all. If you're short on time, light on cash, or just don't feel like leaving the house...give it a try!
