The adductors lengthen to get into position; they may have some role in holding the leg in place by pressing the foot into the inside of the standing leg. Missing the pectineus to hold the leg in place creates flexion at the hip, tilting the pelvis and rotating the leg inward.

Abductors on the standing leg are working eccentrically; if they are weak or tight, the hip of the lifted leg will ” hike up,” or the rotors will try to stabilize the pelvis and the pelvis will rotate open.

The more strength and adaptability you have in the feet and ankles, the more options you will have for finding blance.
