I don't know if you'd call it a real exercise regime, but after I roll out of bed, get dressed, shave, have breakfast, etc., I head out to the barn and start moving hay bales around, feed horse and mules, and fill water troughs. After feeding farm dog and barn cats. I head out to the hen house, take care of stuff out there...then head out to the vegetable garden, water, weed, and harvest anything that needs harvesting...then weed some more. (Ugh!)
Next, depending on the day, I'll either head out to the orchard or my mini-woodlot and take care of the watering there. This time of year, I'm also thinking about the woodshed that needs filling...so sawing, splitting, stacking will sometimes take up part of the morning, too.
By that time, it's pushing noon, and I'm starting to drag.
So, to be honest, I guess I don't have an exercise regime...but whatever it is I do for the first four hours or more each morning sure as heck has me breathing hard by the time I make it back to the house for dinner.
It must work because I'm only seven pounds heavier than when I was in college...and I'm sixty-six.
