In Chakrasana (Urdhva Dhanurasana), turning the toes out and strongly externally rotating the thighs doesn’t automatically damage the SI joint or lower back. The problem is when the turnout is excessive or forced and your body compensates for limited hip mobility.
What can happen
1. The pelvis can become unstable
When the feet are turned out significantly, the femurs externally rotate. If you then try to straighten the legs while keeping that position, the pelvis can rotate or shift. This may create uneven loading around the SI joint rather than allowing both sides of the pelvis to work evenly.
2. More movement may come from the lumbar spine
If the hips can’t provide enough extension, the body may find the movement by increasing lumbar extension. In Chakrasana, the lumbar spine is already extending, so excessive additional extension can increase compression or irritation in the lower back.
3. The knees can move outward
Strong external rotation can encourage the knees to drift away from the line of the feet. This can reduce the ability of the legs to provide a stable base and may contribute to asymmetrical loading through the pelvis.
4. You can lose the “hip extension” action
A useful action in Chakrasana is to extend the hips while keeping the legs organized, rather than simply trying to rotate the thighs outward. If external rotation becomes the dominant action, the lower back may compensate.
