I agree
You will probably feel an awkward adjustment to your game when you start working out but I think you will find once you get past it that your game might just improve. Healthier body = more stamina, more strength, more balance and control, and usually more confidence. Make sure you're doing a lot of stretching too so you're not so tight when you go to play pool. One of the best road players I know makes it a point to go jogging when he's traveling. Best of luck.
