Sometimes I take video footage of what I'm doing in the gym to make sure my form is adequate.
For me that's been a double-edged sword.
Over the years I had shared with my golf pro instructor some pics of my vacations, that I have on my iPad. I usually bring it with me in the car. And he asked me if it could take videos. Well, of course.
So he used my iPad to make a video of my swings on the driving range. When I saw them I realized for the first time how pathetic looking I really am, the range of motion limited by my spinal issues. I never took another lesson from him, and stopped playing golf with him and others (one of them an RJ member).
I still sometimes go to the driving range on my own when It's early and mostly empty, and I putt at home with a practice mat and ball returner I have. My pro always said I was the best natural putter he had ever seen, I could sink 40-footers and better from the first I tried. Perhaps my deadly aim, plus my drives were unfailingly accurate, too, were related to my expert skill with weapons, earning the Army's highest recognitions, and even skeet club honors.
One time he asked me to drive a ball into some trees, pointing to a wooden telephone pole. The idea was to teach me how to use foot placement to drive in different directions.
"That pole is my target?" "Yeah". So I hit the damn pole, about 100 yards out. His jaw dropped open. I expected to get close, but hitting the pole was icing on the cake. For whatever reason my aim is always deadly, whether handling a golf club, a bow & arrow, or firearms.
I do like golf, but no longer in public. That video really upset me, and terminated my being able to go golfing with others ever again. And nothing I can do about my spine, I'm stuck with it. A video of yourself can be instructive & helpful, and I'm glad it's been for you, but in my case a cringing career ender.
