Rotate The Arms
Arms are designed to rotate and counter-rotate when we push, pull, reach, and so on. When arms do not rotate we tend to overuse shoulder and lower arm muscles which can lead to injury and conditions such as carpal tunnel syndrome, frozen shoulder, rotator cuff injuries, wrist problems, trigger finger, tennis elbow, and more. Learn to use the arms as you evolved and you will be stronger, more dexterous, and agile in all you do.
Be sure to have your Practice Checklist handy as you do the practices to rotate and counter rotate arms.
