Final answer:
To modify the supine twist if the knees don't fall to the side, one can use a cushion or folded blanket for support. This allows for proper alignment and comfort in the twist.
Step-by-step explanation:
When performing the supine twist and the knees do not fall entirely to the side, one can modify the posture to accommodate their range of motion. To assist in moving the thigh and lower leg into the twist without strain, one may use props such as a cushion or a folded blanket underneath the knees. This modification not only provides support but also allows the individual to maintain correct alignment and gain the benefits of the twist without discomfort or risk of injury.
Variations include adjusting the position while sitting or kneeling to ensure comfort and proper form. It's also beneficial to stay mindful of the arm and elbow placement as they can provide additional support, bracing the posture as needed.
