Integrative exercise for trunk-adductor-coordination.

Triple extension position is assumed laying on the side. The extended leg is up, taking the majority of the weight while the contra-lateral muscles of the trunk stabilize the lumbar spine.

Adductor strength in axial stabilization of the leg is crucial, especially during the stance face. They inhibit excessive medial translocation of the knee while ensure horizontal pelvic stability.

At the same time the muscles of the trunk on the swing leg side must also actively engage in pelvic stabilization.

This exercise mimics adductor & trunk co-activity in the stance and later triple extension phase.
