Hi!! I am Arianna’s friend! Okay, I don’t want to start out on a bad foot, so I do want to say that lungeing is useful too. 1) longe lining teaches a horse to respond to rein pressure and rein cues, which is what they really need to know. (Why would you teach a horse to go forward from the side? That is not what you do in everyday riding.) 2)Longe lining can build muscle before you ride them as well. (And is keeps you in shape too) lol 3) It shows the horse that he/she is not the only one doing the work. You’re not just standing around in the center ordering him/her around, but participating in his/her workout. But lungeing is good too, because you can school novice riders, and if you are being lazy, you can do stand around in the center (lol). Please, no hard feelings anyone!
