At 52 I have to! I found out a couple of years ago I cant even take off a few months, I finished a 10 day elk hunt that I hiked 7+ miles a day, when I got home I figured I would take some time off to recoup. Bad Idea. Went I went back to my routine I felt like every joint had locked up, I had pains in places that had never bothered me, so I decided then to try and do a little something 5 or 6 days a week. I hike in the local hills 5.5 mile 3X a week and do a push ups, pull ups, planks routine three times a week. Feel a lot better when I keep after it all year. I am running from old age, but every time I look over my shoulder, it is getting closer! I had to drag out a deer this last year at 8000' elevation and backpack another one out my myself, man I can't wait for my son to finish his hitch in the Marine corps this fall. I need some help!!! Good luck to everyone in the drawings!
