Begin by standing on a comfortable surface,
where you have plenty of room at each side.
With a 5-lb potato sack 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 sacks. Then try 50-lbpotato sacks
and then eventually try to get to where you can lift a 100-lbpotato sack 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 of the sacks.
