Ok just reread your post…where you said he would go around happy in a basic connection “like a hunter”. That made me think about things.
When I school the basic stuff…circles, serpentines, voltes etc…it isn’t a hunter type I want. Even if it is a hunter with a soft rein connection. That’s nice and pleasant but it isn’t athletically conditioning and training a dressage (wannabe!) horse.
Even youngish horses I really really want that bascule shape…like a dressage whip when you pull on both ends and make that arc shape. I want to work towards lifting the back, engaging the tummy muscles and tipping and engaging his pelvis. it is basic work to the onlooker -maybe looks like the same stuff you’d do when “flatting” your hunter…i dunno. It’s different when aimed for dressage and takes a fair bit of rider feel.
But it is done with a real emphasis on getting the horse to carry you the rider with his whole body involved. Right from the hind engine over the back, with a long but stretchy neck. That is the only way a horse can happily carry the weight of his rider…he has to learn to engage his whole body and lift and step thru.
So I guess it is a long winded way of saying doing the basic exercises like a hunter…isn’t promoting his dressage muscles. I am rabid about this stuff…it works. It doesn’t look like much - and riders dont’ think it’s difficult…it’s just flat work - but it is really - you have to have good feel. But if you keep at it and doing it with a view to engaging your horse’s core and whole body it makes a huge difference - my 16 year old pencil- necked hadn’t been ridden in 4 years Trakehner - now in his early 20s has totally rebuilt his topline. He looks like a GP stallion…(OK in an elderly statesman sort of way). But seriously he looks amazing for his age - and it isn’t that the work is dramatic or strenuous…it’s he moves in a overall round way and reaches for contact. He isn’t allowed to trundle along hollow backed - it does him no good at all that way. It is just miles on the legs he doesn’t need.
FWIW anyway…this from a person who would consider an animal communicator…so I know it lowers the value. LOL
