I am considering purchasing the gelding below (provided the vet check goes well) and am wondering what my conditioning regimen might be. I certainly want to focus on his topline, but should I be working on strengthening other muscles first? He's a trail horse now but I'd like to eventually have him going English. Also, tips on his nutrition? I believe his owner currently feeds him 12% sweet feed and he is out to pasture. Not sure about hay.
