Shoulder in, haunches in and half pass are related to each other.
|Doing a half-pass is the same as quarter-in, except that the exercise is not done along the wall bet on the diagonal.This requires that the horse carries itself as the wall no longer supports the horse. Imagine that the wall is on the diagonal and ride hindquarter-in along that imaginary wall. This will result in the half-pass.||In the half-pass the shoulders should always lead, meaning they are always in front of the hindquarter. During every moment of the half-pass, the horse should be able to continue in a straight line in shoulder-in. Then you are sure the horse has had the right shape during the half-pass. For horses that still lack some strength and lose their balance quickly, it is recommended to alternate half-pass with shoulder-in on a straight line.|
