Take a look at the photo again. Would it not make sense to consider modifying your practice routine based on what this snapshot is showing you? You should still warm up and activate your golf muscles but a wise move would be to devote a third of your practice time to your wedges and another third to your putting game. And be sure to conduct this practice with focus and purpose.
And other golfers don’t take practice strokes at all. I’m simply recommending that you try the preview strokes I’ve described here and putt with your last thought being “That’s perfect!” rather than “I hope what I’ve been thinking feeling and doing are right.”
For this “Backspin vs. Lie” experiment you’ll need your lob wedge a tee and three balls. Select a 20- to 30-yard shot around a green that forces you to carry a bunker but that provides plenty of room between the apron and the pin.
