My new Exercise Program

I'm nearly a senior citizen.  It's time to modify my behavior so that I can stay in shape.  Here's my new program and I highly recommend it to all, old and young.  It seems pretty easy.

In order to build muscle strength in the arms and shoulders. Start slowly, just three days a week. 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, 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 sack. Then 50-LB. potato sacks, and eventually try to get to where you can lift 100-LB. potato sack in each hand and hold your arms straight for more than a full minute. 

After you feel confident at that level, put a potato in the sack.
