Thanks, Michael Gary Duncan, Mark Wilson and Barbara Michalak for you reactions to the "no pain, no gain" approach to exercise. My trainer agrees with you; in fact, in our session, this morning we were very careful to work the ranges on the machine in which there was no pain. I asked the question since I knew that to be a previous aerobic workout view and that we are more likely than most to have to deal with that problem. Thanks, Bette Ide for your information on the Acquajogger. I am signing off for 10 days, going off to the Colorado mountains for the Spring Break. Will be back on line on the 14th and will catch up with the back mail then. Take care, everyone. Bob Newbrough ([log in to unmask])
