Doorway/Wall Chest Stretch
This stretch focuses on the chest (pecs) and the front of the shoulder Stand near a wall and place the forearm of the arm you want to stretch against the wall with your elbow at least a little below shoulder level.
With your hand secured against the wall, rotate your torso forward (away from the wall). For example, if you are stretching your left arm, you rotate your body to the right. Make an effort to keep your shoulder down and relaxed during the stretch and find the position that stretches your chest the most.
You can move your forearm a little higher or lower if it gives you a better stretch, but don’t move the hand so high that it forces your shoulder to shrug/move towards your ear. If you are having trouble feeling the stretch or finding a good position, try taking a step forward with the foot closest to the arm you are stretching. This position can give you more stability or give you more leverage to target the stretch to find the tightest part(s) of your muscles.
Whichever position you use, be careful not to apply too much pressure. Feeling discomfort in your shoulder, elbow, or neck happen when pushing to hard.
