To what position should the arms be lifted during the Y raise on a Swiss ball?

In a Y raise performed on a Swiss ball, the arms should be lifted to the positions approximating 10 and 2 o'clock. This positioning allows for optimal engagement of the muscles responsible for scapular stabilization and shoulder mobility. The Y shape formed by the arms creates a pathway that emphasizes the upper back and shoulders, enhancing the effectiveness of the exercise in promoting proper posture and functional strength.

This angle not only targets the appropriate muscle groups but also minimizes the risk of shoulder impingement while providing a safe range of motion. Positioning the arms in this way ensures that the movement is performed effectively, promoting stability and alignment during the exercise.
