Rectus Femoris

Composing some of the central mass of the front of the thigh, the rectus femoris is a muscle which is one of four which together are referred to as the quadriceps, and commonly responsible for extension of the knee.

Targeting the rectus femoris in an isolation manner can be achieved with the leg extension exercise, which placed resistance against the extension of the knee via recruitment of the quadriceps. The leg extension exercise also allows for isolateral training, performing the exercise with each leg, ensuring each leg receives equal work load.

The squat is often seen as the main lower body exercise, recruiting the majority of the lower body muscles is one compound movement. This exercise may not be suitable for those who suffer from lower back issues, or have any upper body injuries, and the leg extension may provide a more suitable quadriceps exercise in such a situation.

When training for muscular size it is often best to train in a rep range of 6-12 repetitions, although there is often much debate on the optimal rep range. It would be advisable to experiment with different ranges to see which suits you.
