Just came across this exercise suggested for older people, 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. The article 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 try 50-lb potato sacks and then eventually try to get to where you
can lift a 100-lb potato sack in each hand and hold your arm straight
for more than a full minute. (I’m at this level)
After you feel confident at that level, put a potato in each of the
sacks.
