I must admit, my age might be starting to catch up with me. I had just been feeling...not strong. So I went to my doc, and he put me on an exercise program. He told me to begin with a five-pound potato bag in each hand. Extend your arms straight out from your sides, he said, and hold them there for a full minute, and then relax. So I did. After a few weeks, I felt like I could do this exercise pretty easily, so I called me doc and he told me to move up to ten-pound potato bags. Then try 50-pound potato bags, and eventually try to get to where you can lift a 100-pound potato bag in each hand and hold your arms straight for more than a full minute. Well, it took me several months, but I'm at the point now where I can hold the 100-pound potato bags with relative ease, so now I'm thinking about adding a potato to each bag.
