I'm not one to really give advice on something like that. I will just state what's been working for me. My paso was terrible, had no muscle, etc. He was kept in a small corral. Since being turned loose on our 40 acres he's muscled himself up just walking around. When I first got him his chest was almost concave. Now he has firm muscle there. I'm pretty happy about it and it required 0 effort on my part.
