As the back fatigues, swing mechanics can start to fail and golf balls go astray. Strong low back and Latisimus muscles will help you to focus on and effectively execute the task at hand. Keep your body tilted slightly forward. Keep the back flat. This helps maintain your spine angle throughout the golf swing.
Knees are bent and abdominals are tight.
Now with your arms slightly bent, lift your arms to shoulder height. Exhale as you lift. The back of your hand should move toward the ceiling. Complete 12 to 20 reps for two to three sets. With the opposite hand, grab the back of the elbow and pull the straight arm across the body.
