Workout 1 of this 2-part series focuses on the posterior rotator cuff muscles and tendons. You'll need a light to moderate resistance Theraband (resistance tubing works as well; just make sure it’s long enough and not overly hard to stretch).

Use this as a warm-up before a strength workout, or a stand-alone if you have shoulder/rotator cuff issues.

Tools: Theraband (or long resistance band)
