Equestrian rider training harness

A harness for use with a rider seated astride on a saddle secured atop a back of horse by a girth strap extending around a barrel of the horse from either side of the saddle, the harness for reinforcing recommended saddle-sitting techniques and comprising:

• a loop comprising an assembly of interconnected straps and buckles, the straps including a first strap, a second strap, and a third strap, and the buckles comprising a first buckle, a second buckle, and a third buckle each openable for opening the loop;
• the first strap extending between the first buckle and the second buckle, the second strap extending between the first buckle and the third buckle, and the third strap extending between the second buckle and the third buckle;
• the first strap including a back support between the first buckle and the second buckle;
• the first buckle, the third buckle, the first strap extending from the back support to the first buckle, and the second strap extending from the first buckle to the third buckle comprising a first section of the loop;
• the second buckle and the first strap extending from the back support to the second buckle comprising a second section of the loop opposing the first section of the loop;
• and
• the third strap extending between the second buckle and the third buckle comprising a third section of the loop;
• the loop configured be wrapped under tension around the horse from the back support applied against the rider's lower back so the first section and the second section extend outward, downwardly, and forwardly from the back support over either side of the rider and downward along either side of the horse, the third section extends over the girth from the second buckle to the third buckle below the first buckle, forward tension exerted by the back support against the rider's lower back urges the rider to sit upright, and downward tension exerted by the first section and second section against either side of the rider urges the rider downward into the saddle.
