For me it was cleaning stalls at $10(80’s dollars) each at the barn where I learned to ride, then my pick of the horses that needed work after I was done. No wonder I could run a mile in decent time with no other exercise than that. I could also eat a whole large pizza by myself - the rare times I got one- and not gain weight. Bonus feature was learning to be able to stay on most any horse no matter how rank it was.
