Pilates, kickboxing, and pole dancing can tone, but the interval training in Kristi Molinaro’s signature class will do it faster. Bursts of high-intensity exercise (like her squat thrusts off a step while holding a body bar) interspersed with active recovery (in other words, biceps curls while you catch your breath) are similar to the regimens created for professional athletes training for peak performance, according to NYU professor of physical therapy Dr. Marilyn Moffat. You may not be destined for Beijing 2008, but you’ll be clearer-headed, with a better fat-burning and cardiovascular efficiency. Molinaro’s goal is to push everyone against his or her own limits, so everyone, even the triathletes, are gasping at the end.
