Hitting the ball well off the tee doesn't guarantee a good score, but it certainly helps. It helps to build confidence, it helps to build momentum...it helps to not have your ball 2 meters underwater.
Here are a few drills the golfers here at Hole19 have been using to help them drive more consistently and keep them on dry land:
Hit on the upswing and preserve your distances
3 tees can help you strike it right every time
Dance your way to better rhythm and timing
Keep 'on plain' with a practice stick
Another one to keep you on the right plain...no practice stick necessary here
