pool credit

Is there anyone out there that has to alter their stance because of a sore neck? About two years ago I started having neck pain. Went to the chiro, he told me to get some X-rays, after 7 x-rays, yup you got some arthritis. Went back to the chiropractor and he gave me an exercise to do to strengthen the muscles in that area. When I was a letter carrier I had back surgery in 2004. The surgeon said "here if you don't do these exercises, you're going to be back for a fusion. Been doing them since. I did something with 1 of the surgeon's and the chiropractor's. I call it my neck-butt exercise/ pool credit. NBX/PC for short. In the morning before I go down and shoot, I start with 3 of these. And then anytime I go shoot the rest of the day, I have to do 1 of these exercises before I pick up a cue. The first time I shoot every day I write down a Pool Credit (PC) Rating (PCR). Then the rest of the day I see how much better or worse I do.  Lester  PS  I hope to get this exercise on video for my website.
