Prior to stretching and exercising, apply moist heat to the shoulder. This loosens and soothes the joint and surrounding muscles. Microwavable heating pads are available in a variety of sizes, some filled with aroma-therapeutic scents. They are an excellent household item, especially for the exerciser. If you don’t have a heating pad available, apply a washcloth soaked in hot water. Leave heat on for 10 minutes prior to beginning your program. When finished, apply an ice pack for the same. Ice will reduce any inflammation that flared during your efforts.
