so now that i'm in my mid 40's, and have had a desk job for the last 18 years i think it caught up with me. I used to like practicing or playing 9 after work, but recently I've been so sore and stiff that I don't feel like it. The last few times I went to the range or played a round I feel like my flexibility has went to none. I have access to a number of gym memberships through my work, but have never went. I would like some suggestions for what to work on at the gym to try to increase flexibility, stamina, etc., for a beginner. I feel I could probably fit in an hour a day, maybe 4 times a week. I don't want to get a personal trainer or anything, at least not yet. For now I thing anything would be better than nothing.
thanks
