Leg extension: how to do it with good form
The leg extension machine isolates the quads and is a good complement to squats and leg presses.
How to do it
- 1
Set the back pad so your knees line up with the machine pivot and the pad rests on your ankles.
- 2
Hold the handles and sit back against the pad.
- 3
Straighten your legs and squeeze the quads at the top.
- 4
Lower slowly back down.
Common mistakes
- Swinging the weight up with momentum.
- Lifting your hips off the seat.
- A weight so heavy the movement gets short.
