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-lb potato sacks and then
eventually try to get to where you can lift a 100-lb
potato sack in each hand and hold your arms straight
for more than a full minute. (Potters at this level.)


After you feel confident at that level, put a potato
in each of the sacks.
