“Stretch on the wall” Stand sideways to a wall. Flex your forearm against the wall and then turn your upper body further up. You will feel a pull in the chest muscles or in the armpit area.
Hold the stretch for 10 seconds and then change sides. Each side should be stretched 2-3 times. Alternatively, you can also stretch the chest muscles in a door frame. To do this, flex one or both forearms on the frame and take a step through the door. Back to the article
