EXERCISE FOR PEOPLE OVER 50
Begin by standing on a level surface, where you have plenty of room at each side. With a 5-lb potato bag in each hand, extend your arms
Straight out from your sides and hold them there as long as you can. Try to hold 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.
