Exercise For Seniors

Just came across this exercise suggested for seniors to build muscle strength in the arms and shoulders. It seems easy, so we're passing it on. 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, then 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 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; but be careful ...

That looks like something I may be able to do. Will give it a try. If you don't hear back from me, I probably fell over lifting that 100 lbs sack. Good day to all

Sounds like it will work with my two 8 pound hand weights.
