Shallow your Downswing!
If you want to hit the golf ball further, more accurately and more solidly then you want to work on your downswing being less steep, so that you can rotate your body more through impact.
A steep downswing results in you using your arms far too much as you strike the golf ball, which reduces your power and club face control.
Try this easy to set up drill to get your arms closer to your body on your downswing when you are next at the range, so that you shallow your downswing and make a better body turn and swing, through impact.
