Which of the following best describes over-tracking?

• A. Over-tracking describes a horse in a loose, extended frame with reduced impulsion.
• B. Under-tracking refers to the head position alone.
• C. Over-tracking describes a tight frame and more collected, generating greater impulsion.
• D. Over-tracking describes a horse in a tight frame and more collected, generating greater impulsion.

Answer: (D)

Over-tracking is about how the horse carries itself and uses its hind end to create energy. It means the horse is in a tighter, more collected frame with the hindquarters engaged, which produces greater impulsion. This makes the movement feel more compact and powerful rather than loose or extended.

The other descriptions miss this combination. A loose, extended frame with reduced impulsion describes a less engaged horse and lower energy. Focusing on head position alone neglects the way the hind end and overall carriage contribute to impulsion. So the description that ties over-tracking to a tight, collected frame with increased impulsion best captures the concept.
