So I've taken about 6 riding lessons now. In the last lesson, we trotted for the first time. I didn't last long because it *hurt* in a certain way...let me put it this way, if I were a gelding, there wouldn't be a problem. I'm not joking, if I don't figure this out, I done with horses. Can any guy out there make suggestions?
I know this seems kind of odd for me to be saying this, sence Im not a guy in all but.....alot of my guy friends were padding (like a socks, washcloth, etc.) with a cup. Haha Im like one of the the guys so they talk about everything around me.
The key to trotting (and riding in general) without bouncing and getting sore in many places down there is to really relax your hips and legs. When I started riding, I was always thinking about all the stuff they tell you about position, heels down/etc/etc/etc, and it made my back/hips/legs stiff and tense, and I was always 'bouncy' and sore everywhere. One day, I decided to 'just ride' and not think about it...and when you are not thinking about it and your lower body is relaxed, you'll find that your body will naturally follow the horse's motion and you'll feel great after.
Learn to Post. Your instructor should be there to teach you.
A difficult part of learning to ride is learning to get in rhythm with your horse. Painted said it well, unfortunately it is easier to say then to do but once you figure it out, it's like someone turns on a light in a dark room and you will progress quickly.
