Hi i really want to get my first horse so that i can learn to ride. I am finally at a stage in my life where we have the room and funds to take care of a horse but im afraid that im too fat to ride a horse. I am ashamed to admit that i weigh 230 pounds (105kg). I really want to start riding soon so that once my son is old enough to start to learn we can ride together. is it possible for a horse to carry me and if so what size should i be looking at.
