30 Minute total body Workout

High-intensity interval training saves time, plus it can improve your cardio strength and keep you burning calories for hours after your workout is over.Physiological adaptations to low-volume, high-intensity interval training in health and disease. Gibala MJ, Little JP, Macdonald MJ. The Journal of physiology, 2012, Jan.;590(Pt 5):1469-7793. But this HIIT routine packs an extra punch: supersets. In this workout, you'll do three moves back-to-back with no rest; then repeat the entire set before moving on to the next group of moves.

This intermediate routine from Grokker coach and certified trainer Kelly Lee comes with tons of modifications, so no matter your exercise level, there's no excuse not to try. You'll enjoy this workout most if you can use a set of dumbbells (or a kettlebell) and a mat, but you can also use your bodyweight. Start with the warm-up, then use your core, lower body, and upper body in nearly every compound move.
