Leg Extension

Directions:

Preperation/body position

1. Set correct resistance on machine. Alter machine settings, if necessary.
2. Sit on seat, back supported by the rear back pad.
3. Place feet beneath the padded lever.
4. Grasp handles to the side of the seat for greater stability.

Excution/Movement

1. Extend at the knee to raise lever upwards.
2. Once peak contraction is reached, control lever to starting position.
3. Repeat for desired amount of repetitions.

Comments

The leg extension is a great exercise which adds resistance to the flexion of the knee, thus stimulating the quadriceps muscles effectively.

The exercise can be great for those who wish to pre-exhaust their quadriceps before the likes of squats, which require greater overall muscle involvement.
The leg extension is also ideal for those who want to execute isolateral training, maybe because of injury to one of the knees. The exercise can be performed in a similar manner, with one leg.

For hypertrophy 6-12 reps will likely yield the best results, providing optimal time under tension. This will provide adequate stimulation for sarcoplasmic hypertrophy, and acute response to anabolic hormone concentrations, compared to that of lower rep ranges.
