Seated Leg Extension Machine Exercise

Starting Position

Follow machine instructions for set up and select desired weight. Sit so that food pad is just above the ankles, thighs are flush with the seat (but backs of knees are off of the seat), and back is straight and supported by pad. Keep knees above ankles, back straight, abs engaged, and hands lightly gripping handles at your sides.

Action

EXHALE: Slowly straighten your knees to push the leg pad upward.

INHALE: Slowly bend at the knees to return to the start position to complete one rep.

Special Instructions

This can be a very dangerous exercise for the knee joint. SparkPeople recommends that you practice extreme caution when doing this move, using a light weight, or avoid it entirely.
