The Gravity Training System (GTS) “Total Gym” works every muscle in the body in order to tone, strengthen and improve flexibility. I’ve had the pleasure of owning one since 2006.

It features a moving glide board and a changeable incline from 1 to 8. Exercises are performed on different inclines to work the muscles using your own body’s resistance against gravity – at the lowest incline you use 5 per cent of your body weight and 59 per cent at the highest.

The GTS can be adapted to cater for over 200 different exercises.
