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. (I 'm at this level.)
After you feel confident at that level, put a potato in each sack.
