Just wanted to say, at my latest doctor visit, she advised me to ride my trike more often, because regular, low-impact, aerobic exercise helps alleviate fibromyalgia symptoms. As long as it is not too strenuous. Better to bike easy on nearly a daily basis than to do a couple of hard strenuous rides a week.
So, if anyone asks me where I'm going, I'll say, "Triking! Doctor's orders!" LOL
