Comments and tips

  • You can also perform the dumbbell Cuban rotation with both arms at the same time, either simultaneously or in an alternating fashion.
  • Use light weights because the target muscle is relatively small. Light weights will also help to avoid damaging your shoulder joint.
  • The dumbbell Cuban rotation is not about building muscle. It’s about promoting shoulder health by strengthening three of the four muscles of your rotator cuff (teres minor, infraspinatus, and supraspinatus; the remaining rotator cuff muscle is the subscapularis). The rotator cuff muscles and their tendons work to stabilize your shoulder, so strengthening them promotes a strong and stable shoulder joint.
  • The target and synergistic muscles are not labeled in the illustration because they are out of view.
