Work your back and shoulders
The rope drill is a quality way to add speed and technique to your shoulder turn while maintaining a great spine angle. Loop a jumprope around a table leg or post and grab one end in each hand. Feel as if you're starting a lawn mower with each arm, while keeping your head steady. Go for 20 repetitions per set and three sets, feeling a nice weight transfer to the left side during each rep. You'll increase your range of motion and power and improve your swing tempo.
