One of the easiest and cheapest training aids for the short game is a driver’s license or credit card. If you struggle with breaking down through impact and flip your hands a lot then place your credit card/driver’s license inside the Velcro on your glove of your top hand so the card is against your wrist. Make a few practice swings keeping your lead hand moving towards the target. If you feel the card bend a little it means you are flipping and most likely making inconsistent contact. Hope this tip helps.
