His biggest problem is that he still protects his back and will brace, evade, throw his head in the air and do the speed up/slow down/speed up routine. Consistency in his frame, gaits, speed, etc is nearly impossible without riding him very strongly up into your hands with your legs and holding him where you want him to be. This is of course not where I want to stay...So I have been doing long lining and lunging in side reins to get him to move out without weight on his back and to lift up through his back and over his poll. He needs to build the muscle before I can ask him to engage and with his bracing, evading, etc when riding it's very hard to get him muscled correctly. I think if I can get him moving right, building the right muscle, etc it will make the riding problems lessen. He is in between being fit and in shape and not right now. So I think when I ride I am asking for a bit too much in the form of engagement and stretching into the bit than he can comfortably give so we have plateaued and I can't seem to move forward.
So my question is... Does this look right? Is he really stretching over his poll and raising his back or is he in some way faking it or evading or using weird muscles? He has moments when he looks like this then he goes hollow again, then he gets this way again. I realize it is hard for him to do and gets tired quickly but I am very afraid of training the wrong muscles. He's the king of doing what is hard in order to avoid doing what you want. Like counter cantering just because, or doing piaffe when he's pissed and doesn't want to move forward when I ask for some collection. He's also the master of the Levade for the same reason...So any advice, comment, critique, other exercises or techniques I could use would be greatly appreciated! I also attached a crappy confo shot that I found so you can see what we're up against and to use as a visual for him lifting his back...
