Which of the following is considered a common error when performing the double-arm, single-leg, Romanian deadlift?

The correct answer highlights that a slight flexion at the knee joint of the supporting leg is a common error when performing the double-arm, single-leg Romanian deadlift. In this exercise, the goal is to maintain proper body alignment and stability while performing the movement. When the knee of the supporting leg is excessively flexed, it can lead to a shift in balance and alignment, making it more challenging to engage the proper muscles effectively.

Maintaining a slight flexion is typically acceptable for stability; however, too much flexion becomes problematic. The focus should be on hinging at the hip with a primarily straight leg for effective engagement of the posterior chain. Correcting this movement pattern is essential for both injury prevention and performance enhancement.

In contrast, full extension at the knee is typically desired in a well-executed Romanian deadlift, as it reflects appropriate stability and allows for optimal force transfer. Maintaining extension of the hip in the non-supporting leg is also crucial for ensuring that the exercise effectively targets the intended muscle groups, particularly the glutes and hamstrings. Excessive rotation of the pelvis is a common error because it indicates a lack of control and stability, which can compromise form and increase the risk of injury. Thus, understanding the nuances of knee
