I have always been fit, in school I got my bell rung playing football didn't care for that, My thing was running long distance. In school they would only let a kid run 3 miles at most, that didn't cut it for me. Cross-country was more my thing running over and thru varying types of terrain at altitude was my gift. I got mixed up with a man down the street when I was a kid we would run to the top of San Gorgonio mountain just about every weekend 11,500 ft going up one side you would gain a vertical mile in less than 8 miles the round trip was 16 miles the other side was about a 20 mile loop but not as steep that was also an up and back in a day. The other side of I 10 is San Jacinto 15 mile loop did it but that was a freeway of people and not quite as tall.
Got my leg blown off and that was the end of anything running, I haven't quit working hard as I can everyday around the house, stacking hay, cutting wood (not always with power tools) just plain hard a** work keeps you in shape better than any gym will, I still manage to get in at least an hour or more of cardio on an elliptical walker 5 days a week. I do lift weights in the winter to stay strong.
Driving a truck for 35+ years takes its toll on a back, mine is still good!!! the only reason is staying fit, if you quit you will go down hill and fast. I see young kids come hunting with us and they cant lift a 150 lbs pannier or a manties up on a sawbuck to save their butt. This year my Nephew and I got a late start getting supplies up to hunt camp, we tied 44 mules in less that 2 hours that's 88 panniers or manties each at 150lbs holding it in place and getting some rope around it to hold it in place so we could get it secured to the side of a mule.
Im not saying im a superman but I don't make excuses as to why I cant find time to stay fit, its not an option its living the way you want at 61 years old.
