Here's my problem...my horse has done this since I first got him, but lately I think it's gotten worse...whenever I start riding in my arena I go a couple of laps around at a walk to let him warm up. I hold the reins in two hands, keeping a little contact but not much. He walks fine. Then I'll do some trotting on a looser rein to get him warmed up there. It depends on what I do from there-sometimes I'll work on transitions, I'll canter, trot, circles, serpentines...whatever. But whenever I come back down to a walk, he won't walk if I have two hands on the reins. If I put the reins in one hand and give him complete slack, he stretches his neck down and out, relaxes, and walks. But whenver I pick the reins up in two hands, even if I still have no contact, he notices it and starts to jig and get really antsy, like he anticipates I'm going to ask him to do something. But when he's like this I never let him trot-I'll keep two hands on the reins and make him walk around the arena until he quits and just relaxes and walks. This usually takes a few laps around, then he'll quit. So I go to trotting or cantering some more, but when I come back down to a walk he starts it all over again. I just don't know what to do. I want him to walk when I ask him to, with both my hands and a little contact on the reins.
