Nan, thanks so much for the info. It looks like I need to bump it up to one hour, instead of 40 minutes. I think at that point, I will be close to my capacity. 80 rpm for 40 minutes is hard enough, but maybe in a couple of weeks, I will add the extra 20 minutes per session. Thanks again for your selfless efforts at sharing all this important info. And Soccertese, good luck with your new program, I hope we can hear about it as time goes on.
