Use a stable chair on a clear, non-slip floor. This recreational activity is not medical assessment or treatment; stop for discomfort.
How to play
Sit well back on a stable chair. When the left or right goal marker lights up, comfortably extend that lower leg to kick, then return the foot before the next prompt. Choose alternating, left-only or right-only play and one of five speeds.

Comfort and safety
- Clear the area in front of the chair and use a non-slip floor.
- Keep the movement controlled; do not lock or force the knee.
- Use a one-sided mode if alternating sides is not comfortable.
- Stop for pain, dizziness, breathlessness or unusual fatigue.
