The Reach

Works: Abs, glutes, quads, balance
Place five cups in an arc on the floor, 8—10 inches apart. Stand on an inflated disc (if you're ambitious, try standing on a balance board) in the center of the arc, about an arm's distance away from the cups. (If a disc or balance board isn't available, a folded towel is a good substitute.) Raise your left foot off the disc, and, with your right hand, reach down and touch the cup farthest to the left. Stand back up, then go down and tap the cup immediately to the right of the one you just touched. Return to upright. Repeat until you've touched all five cups. Switch to your left foot, touching the cup farthest to the right and working your way to the left. Do three sets on both sides.
