Why ride western?

There are many types of riding styles, but in North America and many other places, western is most common as the western riding style was developed according to the needs of cowboys who worked cattle from horseback.
The western saddle is made to distribute weight more evenly over the horse's back so horse and rider can counterbalance the weight of a roped cow.
The seat of a western saddle is comfortable for long hours of riding over rough terrain, which is great for learning to ride as gives a deeper safer seat to ride in.

The saddle horn anchors a lariat when roping cattle and is great for beginners to hold onto until they get their own balance.
