A leg extension machine is a piece of exercise equipment used to build and strengthen the quadriceps muscles in the legs. It consists of a padded seat and backrest, with a lever attached to a weight stack. The user sits on the seat and places their feet on the lever, then extends their legs to lift the weight stack.
Leg extension machines are an effective way to target the quadriceps muscles, which are responsible for extending the knee joint. They are often used as part of a leg workout routine, and can help to improve strength, power, and muscle definition in the legs. Leg extension machines are also beneficial for rehabilitation purposes, as they can help to strengthen the quadriceps muscles after an injury or surgery.
