This was sent by my dad; it made me laugh outloud!
Exercise for people over 50: 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, 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-pound potato sacks. Then try 50-pound potato sacks, and then 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. (I’m at this level.)
After you feel confident at that level, put a potato in each sack.
