duraDisc™ for the Resistance Chair
When using your Resistance Chair®, you can make an exercise more difficult and challenging to your nervous system as well as the muscles in your trunk, simply by introducing a duraDisc™.
The duraDisc™ when used as a seat will help to encourage an upright posture, strengthens core musculature and assists with pain relief in the back and allows for pelvic tilting.
The nature of the duraDisc™, being relatively unstable, forces the user to turn on little muscles on their trunk they would not normally have turned on, when sitting on a stable surface alone. These tiny muscles in the trunk stabilize the spine and help prevent it from being damaged and causing pain.
