How can this happen? Maybe it's my age (pushing 50--hard!). I've been riding a lot, but getting flabby! Maybe I need to hit the weights more? Maybe it's high carb foods?

I went to the gym last night & had difficulty with poundage that I've lifted before with ease. Can riding wreck your muscle mass? I never experienced this in my younger days (late 30's, early 40's).

This reeks.

Anybody else? What did you do?
