Some here might recall I had a slight misadventure last November. Among other things I now have a separated shoulder. I've always been keen ( well, compelled to try to achieve ) on some level of fitness. As you get older every day gets to be like a game of football. I didn't know if I could still do push ups... I decided I'd have a go. I did one and kept going doing 20. Later I did 20 more. Later I did 2 sets of 50. Every time I did within minutes I had to go swing on either a crow bar or a jack hammer to clear a rock blockage on the plant. I kept at all week but on Friday WOW was my chest sore. But in a good way if that's possible. I'm keeping myself to 2 sets of 50. I wouldn't mind getting back to doing 6 sets of 50 during the day as I used to, then I'll add all the other stuff. You're a long time dead in a box, you really owe it to yourself and those around you to be as fit as you can be. That's not ripped athlete fit, that's as fit as you can be.
