For this move, you’ll need a lacrosse ball as well as a yoga block. Place the ball right on your upper chest muscles, above one side. Take the yoga block and place it on top of the ball. Press the lacrosse ball into your chest with the yoga block and make small circles. Go counter-clockwise and then go clockwise. You can create pressure into the ball using your hand, and you can also use a wall. Repeat on the other side.
