Arch and curl your fingers so that they make the shape of a “C”. With your hands in this position and firm fingertips firm, begin to make circles on your chest. (You can also use a tennis ball, gripping it in the palm of your hand, and working it around in circles).
Work your way from your upper-middle chest out to the side. As you reach the area where your arm meets your torso, soften the pressure. (You don’t want to press too hard in this area because there are nerves close to the surface here that don’t like deep pressure.)
Gently but firmly plant your fingertips in the area where your arm meets your torso. With your arm outstretched, slowly move your arm around in small circles. You should feel the muscles rolling under your fingers. This gives your pectoral muscles some cross-fiber friction, breaking up points of tension.
Repeat on the other side.
