This quality wooden rocker board with cork surface has a 12º tilt. The difference between a rocker board and a wobble board, is that a rocker board will only rock either forwards or backwards, or side to side (depending on how you position the board). The rocker board helps improve posture, strengthen abdominal muscles and tone the hamstrings and calf muscles.
The rocker board is helpful for anyone who has undergone knee surgery, cartilage and ligament operations as well as those with arthritic joints. It cleverly enables muscle strengthening exercises even from your armchair!
