Hi "Asked" -- I posted the lengthy bits of advice a few weeks back.
Just wanted to let you know the 4.0 stuck in year-end ratings. Now comes the big challenge. I will play on a >40 team and a >55 team at the 4.0 level this year.
I know that, if I do not get back to working hard on fitness, I will not stick at 4.0. I need to lose about 20 lbs. and increase strength 10%. Nice to have a goal.
Good luck to you -- I am convinced you will make it with your dedicated efforts. Just remember, your strokes are probably already good enough. It is your mental and physical preparation that will make the difference...
