That's the question I ask myself. If you have stuck with the game of golf for any length of time, have asked a similar question. Even if you've thrown your clubs in the local reservoir and sworn to never grace the green kingdom ever again, there's that lagging question ...
The Video Dilemma
Friends help friends golf sober. We can get lost trying to replicate swings that look good to us. Google is not your friend. We all do it. The rabbit hole of online instruction is simply overwhelming and can trap you in a spiral of frustration and poor play.
Video can be good with two caveats. The video should include you and only be assessed by a PGA Professional. I am speaking from the heart here. Prior to video replay being accessible to everyone on the planet, how did we learn the game and get game improvement advice? A pro (or very good student of the game) watching us, using their brain as video replay, and verbalizing the 1 or 2 things we can do to get to the next level.
I found an amazing gem of a teacher at my local PGA Super Store. He's a Texas Wesleyan hall of famer who played in 13 majors as a tour pro. And he's in Plano, TX giving reasonably priced lessons to any fool that wanders in to the golf megastore. These guys exist in every city. Go find one.
I got 3 lessons, the first since my grandpa had taught me 35 years prior, and he pinpointed two things that improved my game immediately. They are fundamental swing sins that I could no longer see or feel. I retained the videos he spoke over that can we watched over and over. Priceless.
The Strike Plan & The Single Plane
Adam Young & Todd Graves. The Strike Plan & The Single Plane Solution, respectively. The correct strike & the world's greatest ball striker.
I am not one for late night swing help, books, lessons, etc. But if you are looking for an affordable set of video training for golf, I would suggest one of these two guys ... or both. You can get both of their instructional series for less that $100 total.
