Knee extensors

Knee extensors are muscles that allow you to straighten your leg at the knee joint. The primary muscle responsible for this action is the quadriceps femoris, which is located at the front of your thigh. When the quadriceps contract, they pull on the patellar tendon, helping to extend your leg. This movement is essential for activities like walking, running, jumping, and standing up from a seated position. Strong knee extensors contribute to overall leg strength and stability, playing a crucial role in athletic performance and daily movements.
