Leg extension

A weight-training exercise that strengthens the quadriceps (the muscles at the front of the thighs). It is often used to rectify knee problems caused by weak quadriceps. Leg extensions can be performed on a weight bench that has a special attachment or by sitting at the end of a table and lifting ankle weights (figure 37). The exercise is sometimes performed with one leg at a time to prevent the stronger leg from doing most of the work.▪ Begin with one leg extended with the foot behind the padded bar of the leg extension attachment. Hold the bench with your hands, and slowly lower your leg about 45 degrees before lifting again. Avoid lowering it all the way down because this puts too much strain on knee ligaments. Do not assist the movement by swinging your upper body. Repeat with the other leg.Aim to do about three sets of ten repetitions for each leg, about three times a week.

Leg extension

The leg extension is a resistance weight training exercise that targets the quadriceps muscle in the legs. The exercise is done using a machine called the Leg Extension Machine. There are various manufacturers of these machines and each one is slightly different. Most gym and weight rooms will have the machine in their facility. The leg extension is an isolated exercise targeting one specific muscle group, the quadriceps. It should not be considered as a total leg workout, such as the squat or deadlift.
