Leg press

The leg press is a weight training exercise in which the individual pushes a weight or resistance away from them using their legs. The term leg press also refers to the apparatus used to perform this exercise. The leg press can be used to evaluate an athlete's overall lower body strength (from knee joint to hip). It has the potential to inflict grave injury: the knees could bend the wrong way if they are locked during a leg press.

There are two main types of leg press:

The leg press works the following muscle groups:

Varying the angle between the sled and the backrest and/or the position of the feet on the plate puts more emphasis on one or the other muscle group.

As the diagonal leg press involves pushing a weight along an inclined track, rather than lifting it vertically, it is possible for strength trainers to press very heavy weight in comparison to other exercises. For example, bodybuilder Ronnie Coleman is featured in videos wherein he leg presses 2,300 pounds (1,043 kg) for a full eight repetitions. World record holder [Jason Faulkner| has leg pressed 1,000 pounds 60 repetitions in 1 minute unequipped. This exceeds world records for the squat, which are 485 kg (1069 lb) unequipped and 575 kg (1268 lb) with supportive equipment.
