Proponents of bareback riding argue that riding in this fashion is natural, allows considerable communication with the horse, and improves a rider's balance. The drawbacks include a higher risk of injury due to an increased risk of falling off the horse, the potential to develop poor riding form, and the possibility of considerable discomfort to both horse and rider due to the absence of a supporting tree and any padding between the rider's seat bones and the horse's spine. Over time, it is more fatiguing to both horse and rider to ride bareback.
