Before I hurt my neck, I was on the treadmill on a fairly regular basis. I had managed to get a 3 mile run (with 1/4 mile warm up walk and a 1/4 mile cool down walk added on) without thinking I was going to keel over and die.
Stopped doing it after my shoulder started hurting out of fear of damaging it. Then I found out it was my neck, and never got back on the damned thing.
I did tonight. And a mile just about killed me.
I'm also starting simple exercises like push ups and crunches. I don't need to buff up, but my body is starting to look like the 40 year old I'll be in short notice. It's too damned easy to fall into a funk where you simply stop exercising, especially when you have a family and whatnot. But those are just excuses.
Besides, when they finally get around to doing the beefcake "Gun Blogger Guys" photo calendar, I want to look damned good for the October spread.
