I've been riding for several years, riding lessons as a kid and then recreationally ever since, recently I have been taking lessons to improve my horsemanship.
I actually have a question regarding proper riding posture and it's relation to saddle construction and where your weight should be. After looking through some photos from my horse and I's (very first!) outside ride I noticed the following:
I am aware that proper posture should have the shoulder, hip and ankle all in a vertical line with one another should it not? In both of my photos I am aware that I am doing an egregious 'chair' sit.
However, I was always told as a child to put my weight into my heels - if I do so, physics then dictates that the stirrup leather should be perpendicular to the ground, correct? If all of my weight is transferring down into my heels through the leather? In the first picture, the stirrup leather is vertical compared to the ground, meaning I am pushing my weight down through the stirrup into my heel. But to pull my leg backwards into proper position would mean that I would have to remove my weight from the stirrup and artificially hold it backwards to meet up with my hip and shoulder line? Which then, at best, due to flexion of my knee, causes my toes to point straight forward?
My current riding instructor say I consistently sit too far forwards (on the pubic bone, rather than ischiatic tuberosities (sorry, vet student! Haha!)), ie; on my crotch rather than back on the pockets. This has the effect of tending to rock my leg further forward as well, exacerbating the problem.
I am able to accomplish the position she requests, but at the loss of putting nearly any weight into my stirrups since I am holding them back.
Is this due to the way my stirrups are attached to the saddle? It is a Beim Kloster Schonthal (now Courbette?) - I won't be offended if it is, I got it for free! Or am I misunderstanding/was misinstructed to put my weight through my stirrups? I feel much happier when I have my weight in my stirrups and feel more secure, riding with my leg cocked back just feels weird and I wanted to make sure it's what I am supposed to be doing.
I ask that you please pardon flaws in my riding position somewhat - it's something I am working very hard on, and still need to improve upon. The horse I was riding is /super/ green and I was a bit nervous as it was our first time outdoors. <-- Understatement!!!
Sorry for the novel, just wanted to adequately explain my confusion! I am so perplexed, haha. Please help!
