For bringing up functional weak links, not many exercises beat this:
Half-Kneeling Cable Rotation
We live and lift in sagittal-plane dominant environments. The half-kneeling position allows the lower body to find natural synergistic tension and torque at the hips and pelvis from an asymmetrical stance. At the same time, rotation off the cable unit provides the loaded stimulus to challenge different force planes and degrees of rotation directed from the shoulder complex.
The key here is hip and core stability. The stronger and more stable the lower quadrant and core positions, the more force and loading you can tolerate at the cable rotation to boost the training effect.
