For a short workout with fast results, try your hand (and foot) at the Valslide. Developed by celebrity trainer Valerie Waters of Los Angeles, each disk (they’re sold as a pair) has a slippery side that lets your hands or feet glide over a carpet while you do standard strength-training moves. “The sliding motion feels easy, but the Valslide makes you less stable and you’re working against friction, so you’re engaging your core muscles more than you would otherwise,” says Waters. The disks are portable and weigh less than a pound ($30, valslide.com). Do this full-body routine twice or more, two to three times a week. (Note: The Valslide works best on a carpet, but you can do the workout on a smooth floor by using Valslide booties, $7, or towels.)
