A person is lunging a dark brown or black horse with a white blaze on its face in an outdoor riding arena in Estaimpuis, Belgium. The horse is wearing a saddle and bridle and is moving at a trot or canter in a circle around the person, who is holding a long lunge line. The ground of the arena is sandy. In the background, there is a fence, some distant buildings, and a large tree to the right. The sky is partly cloudy, with both blue sky and darker clouds visible. No text is visible in the video.
