How to do the single leg extension

1
Sit in the leg extension machine with your back against the pad. Hook one ankle under the roller pad and hold the handles, other foot resting on the floor or the other roller.
2
Straighten that one leg until your knee is almost fully extended, squeezing your quad at the top. Keep your thigh pressed into the seat.
3
Lower slowly over 3 seconds. Breathe out as you lift and in as you lower, then repeat on the other leg.

Form tip: Use a lighter weight than for both legs, and do not twist your torso or swing the pad to finish reps.
