If you play any sport that requires you to throw an object with strength and precision, then it behooves you to take care of every muscle that has an impact on your shoulder and your arm.
Your shoulder is the most complex joint in your body, with multiple muscles pulling it in every direction, and also allowing your arm to make a full circle, move across your body and also touch your back. Every minute change in direction occurs because one specific muscle is pulling, and the opposite muscle is lengthening to allow the movement.
Every movement your arm makes involves your shoulder, even when the muscle doesn’t actually insert or originate on your shoulder. Your shoulder is an amazing structure, and it is so frequently repetitively strained. The good news is that because of the number of muscles that crisscross such a small area of the body, when you are treating one muscle you are simultaneously treating other muscles as well.
Obviously this incredible joint has many more muscles that will impact your throwing ability. As you read the Shoulder and Arm section you will have a much better idea about each of the muscles that need to be treated to ensure that your throwing arm is at its greatest strength potential.
The shoulder is also one of the easiest joints to self-treat! All you need is a ball. If your muscles are really sore, we suggest you start with a tennis ball because it is hollow so it’s a bit more flexible, or if you’re muscles are well-developed the Julstro Perfect Ball will be better. The Perfect Ball is solid in the center but has a ¼” thick soft layer so you don’t bruise your bone.
