Senior Fitness Regime<br>For those of us heading for the senior years here is a little secret<br>for building arm and shoulder muscles. Three days a week works well.<br><br>Begin by standing outside and behind the house, and with a 5-lb potato<br>sack in each hand .... extend your arms straight out to your sides and<br>hold them there as long as you can.<br><br>After a few weeks, move up to a 10-lb potato sack and then a 50-lb<br>potato sack, and finally get to where you can lift a 100-lb potato sack<br>in each hand and hold your arms straight for more than a full minute.<br><br>Next ... start putting a few potatoes in the sacks, but be careful not to<br>overdo it.
