Well, I finally bit the bullet. I went to the doctors this morning for a check-up. I just wanted checking over before joining a gym. The doc gave me the all clear !
Anyway, I am now a member of Total Fitness gymnasium. I haven't been near a gym in twenty odd years. It didn't come cheap though (£450 / $850 PA) but if I can get into a routine it will definately be money well spent.
I also invested in a heart monitor (a Polar F11). This product came highly recommended by a friend.
I only spent 30 minutes working out in the gym. I still have to do my induction but couldn't wait so I jumped on an exercise bike

. My induction is tomorrow afternoon.
