Fit As A Fiddle and Ready to Go

I don't know why but I was thinking about that old piano exercise book we had learning piano lessons, at the end of each section in the book there was a "fit as a fiddle and ready to go" song that put the ideas together, with a fabulous stick figure exercising. That's how the fitness challenge I guess is working out for me, I'm picking up more pieces each time we do this challenge, so it's pretty awesome, and pretty soon I'll be fit as a fiddle and ready to go. And seriously, my mind is kind of tired and disjointed so if this makes any sense I think I get 5 points :-).
