Incinerating fat is mission number one at S10 Training, a private studio in New York City. “We use a body composition analyzer [a souped-up scale that measures with bioelectrical impedance analysis] to read how much muscle, visceral fat, body fat, and water weight you have an how many calories you burn at rest,” says S10’s founder, Stephen Cheuk. “This data allows you to train smarter, so you’re not doing a workout that doesn’t net results.”
You may not have such high-tech trackers, but you can benefit from all the number crunching that S10 has done to maximize the fat-burn in its workouts. Getting into that optimal melting zone, Cheuk says, boils down to shocking the body with a physical challenge it hasn’t adapted to yet. “Every workout should feel like the first week you came to the gym,” he says.
Cheuk created this high-insenity routine using just gravity and body weight to spark your fat burners as you sculpt every muscle. You’ll alternate between a one-minute compound strength move and a 30-second cardio burst. Max your burn by working a little harder and faster each round. (And if this is the kind of workout you love, you’ll go gaga over our 30-day heart-rate boosting HIIT challenge.)
