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.
