I just turned 40 and started taking lessons after a long 20+ years break. I found a small barn with 4 horses and the trainer is an experienced rider. They have a horse for complete beginners but since I have ridden before the trainer has had me ride a mare that is on the smaller side (I'm only 5 ft 1") but she is what I would call "hot" meaning she likes to go fast and furious. Our first lesson was okay, but yesterday since she hadn't been ridden all week, she was completely out of control and was bucking and cantering all over the place. The trainer got on her for a while and got her to calm down after riding her back and worth on the trail. My question is should I keep going to this barn for lessons? Is this something that comes with horses? The trainer made it sound like she never bucks and the only reason she was doing it was because of my aids being wrong and confusing her. This could be it, but then again I am not confident in the saddle after just two rides so I probably shouldn't be riding a "hot" horse. I would love to hear your thoughts. I don't remember riding being this much of a fight with the horses I rode. Thank you!
