I have tried many methods for putting, and none of them worked very well. I tend to have 42+ putts per round.
Last night I think I finally found a method that works, but it involves lightly pressing the elbows against the lower (floating) ribs. This means that I need to shrug my shoulders up a little. I also need to use my legs and hips to turn (since my elbows are locked to my torso), so longer than 20 feet is going to be much harder than before. While it sounds uncomfortable, it is really pretty natural (except for the shoulder part). It is easy to reproduce, and gave me great putts up to 20 feet out last night.
Does anyone else do something similar?
