Do you have neck pain, shoulder pain, numbness, or tingling down your arms?
This exercise could help.
This is the pectoralis doorway stretch. We suggest you do both arms and you can do one arm at a time or you can do them together. We hold all stretches for 30 seconds in an uncomfortable position, but not a painful position. The pec or chest muscles have 3 different angles of muscle fibers, so we must stretch at a 90-degree angle, as well as a 45-degree angle upward and downward.
