We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
Begin by standing on a comfortable surface, where you have plenty of room at each side.
With a 5-lb. potato bag in each hand, extend your arms straight out from your sides and hold them there as long as you can. Try to reach a full minute, and then relax.
Each day you'll find that you can hold this position for just a bit longer.
After a couple of weeks, move up to 10-lb. potato bags.
Then try 50-lb. potato bags and then eventually try to get to where you can lift a 100-lb. potato bag in each hand and hold your arms straight for more than a full minute. (I'm currently at this level.)
After you feel confident at that level, put a potato in each bag.
Heh. No joke, though. I knew a guy from Idaho, working on his Ph'D, who got tired of the program and returned to Idaho to work in a potatoe warehouse. He later came back to visit, and man, he had got a build, muscled arms and broad shoulders. I can definitely recommend lifting sacks of potatoes for getting in shape. Tossing bales works pretty well too.
Spading up, planting, cultivating and harvesting a good-sized vegetable garden will get you a far more balanced exercise regime. Of course, the poor souls huddled in condos, apartments and the like may have to make do with potatoes, treadmills and such.
