Mini trampoline exercises ("bounce" to the experienced) provide excellent total body training. They will target your lower back, quads, cords, glutes, calves and core, while also getting your heart rate up and pumping to combat cardiovascular disease.
A new study by the American Council on Exercise (ACE) finds that bouncing on a mini trampoline for less than 20 minutes is just as good for you as running, but feels better and is a lot more fun.
