Machine leg extension
Sit all the way back. Line the knee joint with the machine's pivot. Set the pad just above the ankles, not mid-shin.

- 1Hold the handles so the hips stay on the seat.
- 2Straighten the knees until the legs are long. Stop before a hard snap.
- 3Lower until the knees are about 90°. Don't let the stack slam.
Easy to miss: The pad sitting on the ankle joint or mid-shin, or the hips lifting off the seat.
