Jogging.

Not our favourite kind of exercise. Any sort of effort in the exercise department usually causes our blood to run cold in dread.

That's why we're so pleased about Gym Box launching Kinetic Rebound.

The classes actually use your body weight and gravity to help you get fitter. Cardio, combat and strength exercise are all done on a mini trampoline ­ meaning that you get a hard workout without all that stress on your joints.
