Pulling a kid in a trailer made a big difference in my strength going up! I think part of that's mental-not dragging that behemoth wind-catcher around makes me feel so darned light and fluffy!
One of the dudes around here highly suggests taking stairs 2 at a time (don't know what my knees would say about that).
Yeah, at 5'8" and 154# I knows what you mean. I'm working on that, though, trying to get back down to a muscley 134 like back when I did race. What a differece 20# makes...
I used to have an open mind but my brains kept falling out.
