Arm Pull Shoulder Stretch
Stand with your feet shoulder width apart and bring your right arm up and across your chest, parallel to the ground.
Grab your arm just above your right elbow with your left hand and pull your right arm across your chest until you feel a stretch in your upper back and the back of your shoulder.
Hold this position for 20 seconds or more, then switch arm positions and repeat hold on the left arm.
The Arm Pull Shoulder Stretch effectively targets the rhomboids on the upper back and the rear deltoids. This is intended to help improve and/or maintain shoulder mobility, as everyday activities (or the lack of) can slowly diminish it's range of motion. Add this to your warm up and/or cool down in conjunction with any upper body workout routine, including those for toning and strength training.
