The Leg Extension allows for targeted work on the lower body. Its handling is simple and intuitive for both beginners and experienced users, and it's easy to set up with a closure. It can also be conveniently loaded with Olympic weights placed on the storage bar, and it will provide the necessary comfort thanks to its protective sleeves.

Which muscles are activated during the Leg Extension?

The Leg Extension is an isolation exercise that primarily targets the muscles in the lower thigh: the quadriceps, the rectus femoris, and the vastus lateralis and medialis. After a leg workout, this exercise allows you to work on your thighs without engaging the glute and back muscles. However, this exercise is not recommended for people with weak knees, as it greatly stresses this joint.

What weight should be chosen for the Leg Extension?

The weight you choose will be personal: the goal is to select a weight that allows you to perform a set of around ten repetitions. If the set seems too easy, opt for a heavier weight, or simply add additional weights that might make a significant difference. Conversely, if you can’t complete your set, consider a lighter weight.

The aim is to keep your torso upright and not to use momentum from your torso to perform your leg extension; if you need to do that, the weight you chose is likely too heavy.

How to use the Leg Extension?

This rack accessory is very easy to use: position a seat in front of your Leg Extension; here we use a Box Jump Bulle d'air® with a height of 60 cm. Adjust the height of the Leg Extension on your rack and load it with Olympic weights, making sure to secure the load with weight collars. Sit down and once your ankles are positioned against the foam pads, your goal is to contract your leg and lift the weight horizontally, then lower it back down gradually to return to your starting position. Repeat the exercise and aim for sets of dozens of repetitions.

You can also vary the exercises: unilaterally (one leg at a time), in Leg Curl (facing away from the Leg Extension), in descending sets, etc.
