Aging alone will shorten one’s backswing; shortening one’s swing should be undertaken only if your are trying to repair a swing fault. Creating consistency in your short irons could be another reason. If shortening happens because you are trying to create more rotation and less lateral motion in your backswing, trying to flatten a left wrist at the top, attempting to firm up an excessively bent left arm, eliminating a reverse pivot which is usually accompanied by the club exceeding parallel- just to cite a few examples; then a positive by-product would be the swing getting shorter. If swing improvement shortens the swing that’s a good thing. Just shortening the swing can be a slippery slope. Unfortunately Father Time will normally take its toll; no need to rush the process.
