How do I do the arm-across-chest stretch exercise?

The arm-across-chest stretch is designed to increase flexibility and range of motion of the shoulder joint and the posterior deltoid muscle. To perform this exercise, follow these steps:

• Start by standing straight with feet point straight forward
• Take your left arm across your chest
• With the right hand grasp the back part of the left upper arm (just above the elbow)
• Using your right arm, slightly pull the left arm across the body
• Keep the left elbow bent as you pull across the body
• Hold the stretch for 30 seconds.
• Switch sides and repeat
• Perform 2 sets on each side
