Stand against a wall with your heels, tailbone, mid back and head touching the wall. Then bringing your elbows up to a 90 degree angle, keep the elbow as a fixed axis and try to reach the back of your forearms and palms back against the wall maintaining the contact points. Avoid bending your wrist as you reach for the wall and perform 2 sets of 12 reps. This is a great way to address poor posture on someone with rounded shoulders. Having good range of motion through the shoulder, especially with external rotation, allows you to drop the club into the slot on the downswing and avoid swing faults such as casting and coming over the top!
