Complete this full-body toning class on day five of Kelly Lee’s seven-day HIIT Club challenge. In this workout, you will complete five supersets with toning finishers. HIIT workouts combine a series of short duration, high-intensity exercises followed by lower intensity intervals of active recovery. This type of training will get your heart rate up and burn more fat in less time, including an afterburn effect that will help you burn more calories than traditional cardio. Join Grokker Fitness Exp
