I thought I would let you guys in on a little secret I found for building up my arm and shoulder muscles. You might wish to adopt this regimen - 3 days a week, works well.

I start by standing outside behind the house and with a 5 pound potato sack in each hand, extend my arms straight and out to my sides and hold them there as long as I can.

After a few weeks, I moved up to 10 pound potato sacks, then 50 pound potato sacks, and finally I got to where I could lift a 100 pound potato sack in each hand and hold my arms straight out for more than a minute!

Next, I started putting a few potatos in the sacks, but I would caution you not to overdo it at this level.
