HOW TO
Leg Extension technique.
Use a load and range you can control consistently.
- Adjust the seat so the knee aligns comfortably with the machine pivot and the pad sits above the ankle.
- Sit back against the pad and brace lightly.
- Extend the knees smoothly until the legs are near straight.
- Pause briefly while keeping the hips down.
- Lower under control to the same starting position.
