OK . . . . I think this thread has some potential. But I would suggest we focus the discussion here. Let's forget about how screwed up you think TGM is as a book or as a discipline.
How about let's discuss what you have learned since your surgery and what you are teaching now. I'm interested for sure. All the TGM debate is going to go down a path that just leads to a bunch of tired arguments we've already seen before.
So what are you doing in your motion now that has allowed you to play pain free at a high level? And did golf screw up your back in the first place?
