What is a common performance error when performing a step-up?

A common performance error when performing a step-up is unsynchronized leg, hip, and back extension. This error occurs when the movements of the leg, hip, and back are not coordinated, which can lead to inefficient mechanics and an increased risk of injury. During a step-up, proper synchronization is important to ensure that the entire kinetic chain is engaged effectively.

If the movements are not coordinated, it may cause added strain on the lower back or knees and could prevent the individual from utilizing their strength efficiently. Properly synchronizing the extension of the leg, hip, and back helps maintain stability and balance during the exercise, allowing for better overall performance and effectiveness of the step-up. This synchronization also enhances muscular engagement and promotes proper form, which is essential for maximizing benefits while minimizing the risk of injury.

In contrast, the other choices do not reflect common performance errors associated with step-ups in the same way. For instance, synchronized leg extension might actually represent proper form, while overextending the ankle and not using weights are not key issues specifically recognized as performance errors in the context of executing step-ups.
