Begin by standing on a comfortable 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 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.
