As for me, I gardened and now my body is ruined. There are some muscles in my lower back and in my calves that would prefer not to be disturbed. Ever again. I make groaning sounds when I get up, sorta like, "Arggha, oomph, ok now...(then I talk to myself) you can do it, you can go to the kitchen and make some dinner, your upper body is alright, at least until tomorrow morning when the GREAT RECKONING will occur. This is the situation when the physical abuse you heaped on yourself makes itself know the next day, or during the night when you have to pee. You utter little squeaks of surprise and dismay that your arms, back, hands, legs etc. no longer resemble the parts you know and love.
When I first started running 5 or 6 years ago, I had the wrong shoes and no support arch thingys. I couldn't walk the morning after I ran. Literally. I couldn't put my heels on the ground. I could tiptoe around, very attractive. Then the nice man at the shoe store put me on a treadmill and videoed my 'gait', like a horse. He declared that I 'pronate' and he pointed me toward the 'pronate shoes'. Then he stuck plastic sole things on my feet and put my feet in plastic bags which he blew up with a fancy machine. All in the middle of the shoe store. So I sat there until the plastic soles molded to my arches and he stuck them in my new running shoes. It was magic. No more foot pain. So I moved on to falling down while running and I can tell you, that hurts like a mofo. Plus you get big scabs on your knees.
Exercise can be fun!
