Although trampolining provides an intense workout for the muscles and bones, the mat absorbs 80 per cent of the shock from the rebound. This absorption reduces the stress on bones and joints, (like the knees, spine and ankles) and minimizes the chance of injury. Unlike jogging or playing tennis, trampolining provides your body with an all-round workout. Over time, this can result in improved balance, co-ordination and posture. Jumping can even increase the strength in your joints.
