What Muscle Does the Leg Extension Machine Work?

Leg extension machines work primarily on your quadriceps. Your quadriceps are responsible for proper knee extension and knee straightening. Leg curl machines work primarily on your hamstrings. Your hamstrings help bend your knee joint and help position your hips when bending.

The leg extension targets the quadriceps, which are the large muscles of the front of the thigh. Technically, this is an "open chain kinetic" exercise, which is different from a "closed chain kinetic exercise," such as a squat. The difference is that in the squat, the body part you're exercising is anchored (feet on the ground), while in the leg extension, you're moving the padded bar, which means your legs aren't stationary as they work, and thus the chain of movement is open in the leg extension.

The 100-degree angle between the seat and back bad for added comfort full quadriceps contraction and offers an effective lower-body workout.
