Back to basics
For many members, finding clean crisp contact feels nearly impossible. Choose a less lofted club (8 Iron) and use your putter grip. Stand closer to the ball with a narrow stance.
Too often I see golfers taking back too fast and when they start going forward towards impact, they slow down. Make a smooth back swing and accelerate through impact.
Length of swing
Keep it short. The longer your backswing is the more you can hinge your wrists. Keep it simple, keep it short.
Hybrid or Wood
Do not forget to practice chipping with your hybrid or woods. Take your putting setup and remember that the ball comes off the clubface a little bit faster. I see putter being used too often from far away, practice with you longer clubs.
