The engagement of which muscle group is crucial for the clean and jerk?

The clean and jerk is a compound movement that requires a significant amount of power and stability, and the engagement of the glutes and hamstrings is particularly crucial for its successful execution. These muscle groups play a vital role during the explosive lifting phase of the movement.

During the clean portion of the lift, when the weight is lifted from the ground to the shoulders, the glutes and hamstrings are actively engaged to extend the hips and knees. This powerful extension is essential for generating upward momentum to successfully complete the lift. Additionally, strong glutes and hamstrings help stabilize the body during the transition from the clean to the jerk, where the athlete explosively drives the weight overhead.

While other muscle groups such as the abdominal muscles, upper back muscles, and forearm muscles do contribute to the overall stability and control of the lift, the glutes and hamstrings are specifically integral to the powerful hip extension needed for both phases of the clean and jerk. Their engagement ensures optimal performance and efficiency during the lift, allowing an athlete to perform the movement with strength and control.
