While the idea of running a marathon may be daunting, you can do just about anything for 30 seconds, right? That’s the idea behind High Intensity Interval Training – go as hard as possible for a short time, then take a break; rinse, repeat. Researchers say just 20-30 minutes of HIIT can be as effective as 90-120 minutes of lower-intensity cardiovascular exercise for aerobic and anaerobic capacity, blood pressure, metabolism, muscle mass, fat oxidation and more, all for significantly less time.“My personal gym philosophy is ‘in, out and on with it,’” says Christy Guinane, lead boot-camp trainer at Wild Workouts & Wellness in Milwaukee. “HIIT can be done in as little as four minutes.”

As your body “rests,” Guinane says, it’s actually scrambling to meet higher demands for oxygen, fueling an “afterburner” effect that lasts up to two hours after a workout of basically any type. “It should be very intense, so you don’t want the duration to be very long,” says Orange Shoe Gym Brookfield owner Wade Ritchie. A bonus: It’s equally effective for people of all skill levels.
