When you buy the Resitance Chair system, we include a Health Step in the package. However, we also offer replacement Health Steps separately. Position the Health Step behind the chair for calf raises, or use it at the front of the Chair to bring your feet up into a higher position while using the Resistance Anchor Cable exercise cables. Lightweight and durable, the Health Step features a non-skid top surface and measures 22 wide by 4 inches high. Available in forest green.
