Because they don't maintain proper posture or form. They think that if they plod along on a horse and manage to keep their seat, they're "riding". Not true. Good riding takes a lot of work. Balance, posture, form, leg work, reining... all are crucial to the health and wellbeing of the rider and the horse.
Are u referring to fellow riders or people who have never rode. I mean isnt that the whole point? Because if someone sees someone else doing something they're trained to do and they're doing correctly, then is should look easy, even if u know it isn't....
Okay, so besides getting saddle sore, what else is there to it? No seriously, I'm not being a smart alek, I really wanna know. I like westerns and stuff, and I live in a farm town where people ride horses in the country now and then. It looks fun. I think women ride horses more than men nowadays, I wonder why that is?
Because people don't understand the difference between being carried by the horse and actually riding. The only other activity that requires you to do different things at the same time with your hands and legs is drumming. Add to this your heels are your anchor do you have to keep your weight down in them. The horse responds to your seat, legs so you have to know when and how to touch them. Maintaining your balance with your legs and seat while jumping 4' or so, traveling rough terrain, rounding a barrel at 35 mph. Maintaining correct posture do as to keep the horse in balance. Using your legs and seat to extend or collect the horses gaits. I have a standing offer to any PE teacher in my area. One free lesson and I guarantee I will have you begging for mercy. One guy took me up on it and then the word got around...
people think its easy because they have a perfectly trained lazy horse. But for people like me I have a horse that thinks what ever he wants to and usually bucks and rears. It maybe just be easy for people who have a well tempered horse, but for people who don't its hard.
some people find it easier some people find it hard, it depends if you have balance, confidence and a good seat, it also depends on the horse, you can't really say whether horse riding easy unless you've ridden at least 5 different horses:)
its easy to get on a horse make it canter and get off, but knowing someone who has a farm and rides her horse every week there are accomplishments that are hard to do on a horse for example jumping a substantial amount of height is quite the challenge
