21-Day HIIT Challenge

There’s no short cut to weight loss, but when it comes to workouts that produce quick, visible results, HIIT is your best bet! HIIT, or high-intensity interval training, is a training style that alternates bursts of intense exercise, with short recovery periods. For this 21-day HIIT challenge, we’re using some of our most popular HIIT workouts to give you three weeks of quick, but effective training.

Our workout plan consists of interval training, walking/jogging, and rest days. It’s easy-to-follow and the quick workouts are ideal for anyone who doesn’t have hours to spend at the gym. It’s the perfect way to tone your muscles, improve your endurance, and burn some serious calories!

What to Do: Download the calendar and complete the workout assigned each day. Some days, you will also have to walk or jog a set number of miles. You can do this outdoors or using the treadmill at your gym. The important thing is to have fun!
