How to do it
Keep your knee hinge aligned with the machine pivot.
- 1
Sit on the leverage machine and adjust the pad so it rests on your lower shin, just above your foot.
- 2
Secure the opposite leg and ensure your back is against the pad.
- 3
Slowly extend the working leg until it is straight, squeezing your quadriceps.
- 4
Lower the weight back to the starting position without letting the weight stack rest.
- 5
Repeat for the desired number of repetitions before switching legs.
Expert tip
Perform the movement in a controlled manner, focusing on contracting the quadriceps at the top of the movement.
