As golfers, we spend a lot of time hunched over, so it is important to do stretches that open the chest and back. This stretch will help open up the chest and stretch the shoulders and back at the same time.
Stand in a shoulder width stance and interlace your fingers behind your back.
Stretch your arms out straight, even raising your hands away from your lower back.
Hold the position for 8 to 10 counts.
Notice which thumb is on top and switch your grip position so that the other thumb is on top.
Repeat exercise with the new grip.
