Best workouts to lose weight fast-Trunk rotations

This is a whole body exercise. Using the arm as a driver laterally reach from knee to overhead and externally rotate. This creates trunk rotation and in this demonstration a weight is used to create tension and load. Feet are in a sagittal plane stance which prepositions the pelvis in such a way that the load will be different on the facets of the left side of the spine vs the right. The chain reaction goes down to the hips, knees, ankles and of course the feet. The chain reaction also goes up through the thoracic spine, neck and head. Test the exercise with no weight to gage range of motion and balance.
