Exercise for Seniors.

A friend just shared this suggested exercise for seniors to build
muscle strength in the arms and shoulders.
It's so easy, I thought I'd pass it on.
The article suggested doing it three times a week.

Begin by standing on a comfortable surface, where you have plenty of
room at each side.

With a 5-pound 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-pound potato sacks.

Then, use 50-pound potato sacks, and eventually try to get to where
you can lift a 100-pound 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.
