COVENTRY MESSAGE BOARD

Begin by standing on a comfortable surface, where you have plenty of room at
each side.

With a 5lb 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 10lb potato bags.

Next, try 50lb potato bags and then eventually try to get to where you can
lift a 100lb potato bag in each hand and hold your arms straight for more
than a full minute. [I'm at this level.]

Spoiler:

After you feel comfortable at that level, put a potato in each bag!
