The term working gait describes a horse moving with his weight evenly distributed on all 4 feet, swinging his legs freely in long, even, ground covering strides. He is stretched over his topline and his hind legs are well engaged. Any horse moving this way is in a working gait; it may be a walk, trot or canter, but it's still a working gait.  The working gait which is balanced on all four feet differs from a horse moving on his forehand in which he has more weight on his forelegs than rear legs, and the collected gaits in which the horse has more weight on his rear legs than forelegs.
