Starting Position
1. Lie face down on the floor and place the foam roller under one side of your chest.
2. Extend the same-side arm out to the side, and use your opposite hand to support your body by pressing it against the floor.
During Exercise
1. Slowly move your body left and right to roll your chest muscles over the foam roller.
2. Gradually expand the range from below the collarbone to the outer chest area.
3. Stop at tight spots and apply your body weight to apply pressure for 10-15 seconds.
Breathing
Take deep breaths in and slowly exhale to release tension in your chest muscles. Don't hold your breath when applying pressure.
