Exercise

With a 5-lb potato bag in each hand, extend arms straight out from sides & hold.  Soon you’ll find you can hold this for a bit longer.  Try to reach a full minute.  Then move up to 10-lb bags, then 50-lb bags & eventually get to where you can lift a 100-lb potato bag in each hand & hold your arms straight for more than a minute.  (I’m at this level)  Once you feel confident at that level, put a potato in each bag.
