Here is an exercise suggested for adults over 45 and seniors, to build muscle strength in the arms and shoulders. It seems so easy, so I thought I'd pass it on to some of my friends. Just don't over-do it.
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
50-LB.potato sacks, and eventually try to get to where you can lift a
100-LB. potato sack in each hand and hold your arms straight for more than a full minute.
After you feel confident at that level, put a potato in each of the sacks.
