This 20-Minute Elliptical HIIT Workout Will Fly By — and Still Make You Sweat

If you're unfamiliar, HIIT stands for high-intensity interval training. It's a simple acronym but an epic workout, alternating intense bursts of exercise with "rest" periods, during which you'll move at a more leisurely pace. HIIT workouts typically last no longer than 30 minutes, because they're intense when done correctly. (You should be really challenging yourself during the work intervals.) While you can do a HIIT workout using any form of cardio, Wood recommends doing elliptical HIIT workouts because it's easier on your joints. "Cardio can be hard on your knees, hips, or feet, so if you can't swim every day, get on an elliptical and your body will thank you," Wood explains.

That being said, the intense nature of HIIT workouts can be a lot for anyone to take on a regular basis. As a result, Wood cautions clients to limit their HIIT workouts to no more than three sessions per week. "At first, people hate HIIT workouts, but they can be addictive," Wood says. "Don't allow yourself to burn out by doing it too often. A few times a week is sufficient."
