I'm skinny, always have been, and haven't changed weight much when totally lazy and when doing things like crazy. For me that is 140lbs. I'm 5'9".

When I was fast, I was jealous of my friends who would show up at the March crits with a little chunk on their cheeks and some adipose in the abdomen.

As the season wore on, they returned to their lean self and got fast. In reality noone was ever more than 10lbs above the ideal but oh man, losing that weight made such a huge difference. It's not just the weight, it's the journey of getting there.

Don't even try to tell me that 10lbs won't make a difference. I've seen too many examples to the contrary.
