It’s important to keep your shoulders healthy.  Here’s a routine I learned from Dr. Kobrin (Chiropractor) about 20 years ago that is still relevant.  He used this while working with the NY Jets.

He advised doing this routine at a time opposite your workout, on its own.  For instance, if you’re working out in the morning, do this at night for time – 30 seconds to 1 minute per exercise.  This hasn’t worked with my crazy schedule so as an alternative, I do it at the end of a workout for 10 reps per exercise.  It’s a great routine to work your shoulders/rotator cuff.  Remember to keep the weight light – especially if you’re doing the timed version.  There are a lot of small muscles in your shoulders.  This exercise will help with mobility and strengthening the shoulder girdle.
