Marine corps exercise regimen for folks over 60.

For those of us over 60 – this is a great exercise regimen –for you young’uns out there (under 60), just keep it in mind until you reach that magic 60 number!
MARINE CORPS EXERCISE REGIMEN FOR PEOPLE OVER 60
Begin by standing on a comfortable surface, where you have plenty of room on each side.
With a 5-lb potato bag in each hand, extend your arms
straight out from your sides. Hold them there as long
as you can. Try to reach a full minute, and 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 bags.
Then try 50-lb potato bags, and then eventually, try to
get to where you can lift a 100-lb potato bag in each
hand and hold your arms straight for more than a full
minute. (I'm at this level.)
After you feel confident at that level, put a potato in each bag.
