Many of us sit at desks all day, and are past an age where physical fitness is an easy attainment. A friend sent me this excercise suggestion, and I thought I would pass it along. My friend suggested doing it three days a week. Begin by standing on a comfortable surface, where you have plenty of room at each side.
With a 5-lb. potato sack 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, 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 sacks. Then 15-lb. potato sacks, and then eventually try to get to where you can lift a 25-lb. potato sack in each hand and hold your arms straight for more than a full minute.
Once you feel confident at that level, put a potato in each of the sacks.
