Hi Cammy - I’m not an instructor, but just noticed a couple things. At the top, it looks like you may be pulling down a bit with the hands without the body weight shifting forward. And also standing up a bit just before impact with the ball. Just a thought. Others may have better advice than me. I’m learning too. Great job though, considering how long you have been playing. Keep it up!
The main issue with golf is time. When my job and other responsibilities allowed me to play at least once per week and practice in between, I could play consistently in the high 80s. But as a weekend golfer it’s tough to maintain enough consistency to stay in the low 90s. Adding age to the equation makes maintaining consistency even more difficult. It’s still a fun game if you manage your expectations realistically.
