Prone I's are an isolation exercise that primarily targets the muscles of the upper back, specifically the lower trapezius. This exercise involves lying face down and lifting the arms straight overhead to form an 'I' shape. It's highly effective for improving posture, scapular control, and stability of the shoulder girdle. Ideal for those looking to strengthen the back muscles and improve shoulder health.
