What is the recommended knee angle for a still leg deadlift?

The recommended knee angle for a stiff-leg deadlift is around 15 degrees. This angle allows for the proper biomechanical alignment of the legs, facilitating optimal movement patterns while performing the exercise. A slight bend in the knees is important for preventing strain on the lower back and hamstrings, as it reduces the risk of injury and promotes a more effective lift. Keeping the knees slightly bent also helps maintain tension on the posterior chain, which includes the hamstrings, glutes, and lower back, making the stiff-leg deadlift a highly effective exercise for these muscle groups.

While a greater angle might allow for more knee flexion and possibly more comfort, it can shift the emphasis away from the hamstrings and glutes, altering the intent of the exercise. Conversely, a smaller knee angle might not provide enough support for the muscles involved and may lead to strain. Therefore, a 15-degree knee angle represents a balanced approach that optimally engages the targeted muscle groups while maintaining safety and proper form during the stiff-leg deadlift.
