Individuals with limited shoulder mobility should perform the movement cautiously and with a reduced range of motion. Always adjust the machine correctly to prevent joint overload.

Common Mistakes to Avoid
  • Using excessive weight, compromising form and increasing injury risk.
  • Overextending arms or locking elbows, overloading the joints.
