In this instructional video, the presenter demonstrates how to use a lacrosse ball to release tension in the rotator cuff and rear deltoid area. He identifies the target spot on the back of the arm where the rear deltoid attaches, shows how to position the ball between the rear deltoid and the spine, and advises leaning forward and rotating the torso back‑and‑forth to roll the ball over the tissue. He notes that moving the ball closer to the spine increases pressure on deeper rotator‑cuff fibers. The presenter emphasizes that discomfort or pain during the massage is a sign that the tight tissue is being addressed, encouraging viewers to persist despite the unpleasant sensation.

Let's break up the tissue in your rotator cuff using this lacrosse ball. You're going to find this spot on the back of your arm where your rear delt attaches and go right there with the lacrosse ball. I'm going to lean up, stick it right in between those two muscles, and I'm going to rotate back and forth. Once you've hit that section, you can move in closer to the spine and get even more of that rotator cuff meat. As you can see, I'm wincing. It's not fun. The more it hurts is usually the more that you needed it.
