Movement media
Accessible movement summary
Adjust the seat so the machine pivot aligns with the knee and the lower pad rests above the heel. Secure the thigh pad, sit tall against the backrest, and begin with the knees comfortably extended. Curl the heels down and back as far as possible without the hips lifting. Pause, then return slowly to the starting position while maintaining tension.
Key cue: Keep hips pinned down.
