I swing a club most days. I average playing around 45 holes a week. I played my 4th round this week today. Next week I might only play one, 18 hole round. Maybe just 9 holes. Maybe nothing.
I might spend another couple hours a week of just messing around, practicing my short game.
On days I don't play, or practice, I have a swing, practice club I use, just to keep my swing muscles in tune. Maybe 5 or 10 minutes.
The days I don't touch a golf club, I am out hiking with my dogs, and camera. I call this my "leg work" exercise. My legs are an important part of my golf swing.
