I eat really well. I don't think that's a problem.

I just wonder how people do it..
Like Fredwina for example: Not only does she ride every day; she rides hard fast rides.
In a perfect world, I would ride my bike every day to work all year long (not going to happen) so.. would I always be hurting?

My legs look so immensely better than they used to, and I can ride so much longer without "running out of gas" but I do feel pain in those muscles the quads. I found it interesting what you said about balance, because recently I knocked my sacroliac out and have managed to get it back to closer to where it should be by doing some exercises prescribed by Knott (I actually felt/heard a click; one day the left side and 2 days later the right)

but that is different (I think) from the sore muscles in my legs...
