Every dressage rider learns that if the front leg hits the ground first then the horse is on the forehand. Horses that are naturally built uphill are seen as having an advantage. Their conformation makes it easier for their hind legs to hit the ground first - something that is referred to as Diagonal Advanced Placement (or DAP). But I've been seeing more and more photos of top dressage horses where the hind leg pushes off before the front leg does in trot, which is apparently a side effect of DAP. It looks to me like the horse is balancing over it's front leg at the end of the stride, and is pushing off the front leg too. Does the fact that they're weighted over the front leg mean the horse is actually on the forehand, despite the appearance of collection? Or am I interpreting the biomechanics of this action incorrectly? I'd love to hear what other dressage riders/trainers have to say. Image below to show what I'm talking about. The offside fore is still in contact with the ground, whereas the nearside hind has already left the ground. Note: this post is not targeted at any particular rider, the image I've chosen is purely to illustrate what I'm referring to.
