Exercises for people of a certain age
Begin by standing on a comfortable surface, where you have plenty of room at each side.
With a 5-pound potato bag 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 a 10-pound potato bag in each hand.
Then try a 50-pound potato bag in each hand and eventually try to lift a 100-pound potato bag in each hand and hold your arms straight for a full minute.
After you feel confident at that level, put a potato in each bag.
