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 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.
