The Ready State Virtual Mobility Coach is like having a virtual Kelly Starrett in your pocket.
rolfb, one of my go to exercises with the Gemini is to go after the scapula. As you lie on your back on the floor, lift your upper back and put the Gemini vertically along the inside of one shoulder blade. Lie all the way down, and then ‘backstroke’ your arm on the side the Gemini’s on. Make it harder by starting the hand of your active arm on the opposite quad, and by externally rotating that arm as you bring it overhead. I try to do 40 – 60 ‘strokes’ overhead. It does wonders for clearing up the scap for Olympic lifting
