How to do a knee extension

Sit tall with both feet flat and hold the sides of the seat.
Straighten one leg out in front until it is level with the hip.
Squeeze the thigh and hold for a moment.
Lower the foot with control.

Form tips

Fully straighten the knee at the top of each rep.
Keep your thigh resting on the seat.
Stop if you feel sharp pain in the knee.
