I'm looking for some advice or ideas for a pretty green but willing QH gelding I'm working with. He w/t/c, leg yields, turns on the forehand/haunches, haunches/shoulders in, etc very well at the walk, starting on the trot. He jumps 2" courses. Very sensitive and responsive to my leg but really lacks natural forwardness and of course impulsion. If left to his own when I ask him to trot he'd much rather do a slow almost western jog so I have to really make him trot forward. Same at the canter, almost a slow lope and I have to make him canter on a pace that's acceptable for the hunter ring. He's very sensitive so when I close my leg on him he does move forward and respond, he just won't keep going. So I ask him again and he moves forward, and then dies down. If I use my crop he squirts forward... and then dies down. I hate seeing riders who are always driving their horse forward every couple of steps. He needs to learn how to maintain a forward rhythym on his own. We do a lot of trot poles, cavelettis, gymnastics, transitions, lower level dressage, lengthen/shorting strides, lunge, etc. Any other ideas?!
PS- He eats a scoop of sweet feed at morning and night and a half scoop of chopped alfalfa at lunchtime. Always has a salt block in his stall and gets turned out all night. In excellent weight. He gets exercised 4-6 days a week, but he's always the same whether he gets a day off or a week off.
