You'll need a sturdy chair and a set of dumbbells or soup cans -- that's it. Do one set of each exercise in the listed order. Complete the circuit, then repeat. Aim for 8-15 reps per set.

To dial up the calorie burn, take as little rest as you can between exercises. The goal is to feel worked and sweaty by the end of the 15 minutes. You'll get results by doing this workout 3-4 times a week with a day's rest in between workouts.

To add an additional challenge and pick up your cardio, do jumping jacks or jump rope in between sets.
