These two pictured horses with more or less similar conformation are reaching very differently with their hind legs. Both horses are in a trot, on different diagonals but that doesn't matter. The top horse's hind footfall will land behind the forehand footfall on the same side. The bottom horse's hind footfall with land in or ahead of the forehand footfall.
The bottom horse is reaching further under itself with the hind than the top horse. The bottom horse is more balanced because keeping the hind footfalls landing in or a head of the forehand footfalls means that there is one center of balance under the horse's belly in a trot stride.
The top horse is not reaching under with their hind and the footfall will not reach far enough ahead to land in the forehand footfalls. There is a gap between the hind and forehand footfall, meaning the center of balance under the belly is not shared but separated. This creates a front-hind-front-hind-front-hind, back and forth balance point under the belly in the trot.
The reach indicates that the top horse is pulling the trot stride forward with the shoulders while the bottom horse is pushing the trot stride forward from the hind. Pushing from the hind is better. As they say, we want to ride a horse "back to front" to achieve lightness and optimum balance with suspension. We do not want a horse pulling its hind around as if it is a little red wagon.
I use a garden rake to smooth a section of arena footing 6 feet (2 meters) wide and three trot stride long. We then trot a horse through the smooth footing lane so we can see the footfalls and the reach, or lack thereof. To correct a lazy hind that is not reaching, we must do the work of engagement.
This means engaging the hind muscles to increase hind reach in order to achieve a truly centered balance point under the belly. Collection work is not cranking down the reins to cork up the energy of the forehand so the hind energy can catch up. That would be false "collection" that creates a false frame of balance, something we see a lot of today. Instead, we need to carefully and deftly hold the forehand together while, with a deep seat and leg, we encourage our horse's push from its hind.
It is good to always observe footfalls and reach. For me it is the first step in evaluating a horse's movement.
