This drill is great for people stuck in an office or in bad weather, hook the right hand under the left and practice your backswing and downswing with a perfect right and left wrist position
Understanding your equipment is necessary for good golfers; hit down with irons to make the ball go up and hit up with metals to hit longer
Don't make things more complicated than they need to be; use the same swing in and out of the bunker and take advantage of the bounce in your sand wedge
