In the Bent Leg Body Twist, what is the required position of the knees and hips?

In the Bent Leg Body Twist, the required position of the knees and hips is to maintain 90-degree angles. This positioning is crucial because it ensures that the lower body is stable while the upper body engages in twisting movements. The 90-degree angle allows for a proper range of motion in the spine and helps maximize the effectiveness of the exercise while minimizing the risk of injury.

When the knees and hips are positioned this way, it also helps engage the core muscles effectively, which is an essential part of performing the twist correctly. This alignment supports the stabilization of the pelvis during the motion, allowing for a controlled and safe execution of the twist.

In contrast, keeping the knees straight and locked would not facilitate the necessary movement dynamics in the torso and could lead to discomfort or injury. Positioning the knees and hips too close together or raising them above the torso would also detract from the exercise's effectiveness, as it would alter the intended biomechanics involved in the twist. Thus, achieving 90-degree angles is fundamental for optimal performance in the Bent Leg Body Twist.
