Try this HIIT full body toning workout for fast results! [Videos]

Most of us are just beginning to get the hang of HIIT exercise but they may not know that its one of the most aggressive exercises for fast results.

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 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 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.
