I have to admit I admire those of you with the fortitude to play in what I would consider bad weather and I particularly admire those who study the game when they can't play. When I lived up north, if I read golf books or watched golf movies when I couldn't play, it just aggrivated me more.
The closest thing to effort I've done on my own, not counting some recent lessons, was to buy a heavy club and a Swing-Stik
The heavy club is to stretch with if I can't get to the course early enough to hit balls and the Swing-Stik is nothing but a grip on a pole with a swing speed meter in it, but there's a cd telling you how to turn its use into a whole golf oriented exercise program. I'm kind of getting into it because I can take it into the back yard for 5 minutes at a time 4-5 times a day and stretch with it.
In the meantime, my diet is doing reasonably well, but my coworkers always want to eat pizza. I may just kill them all!
Admittedly, after a few years of not playing at all, I have the bug again in the worst way and can't stand to play poorly. I just HAVE to get my game back and I'll do what it takes.
