I knew that this would apply to either western or english. I have a 5 year old gelding that I ride 6 days out of the week. He is in perfect shape, very* healthy. I don't have any inclines, hills or sand. I want to know how to fill in that place on his rear end with muscle. I ride western if that helps. P.s. I do back up everyday numerous times because it was suggested to me by an old cowboy friend of mine.
Thanks ahead of time:))
