so it's kind of a style thing? I think my instructor is doing it because it helps me to learn not to grip in the knee but also now that I've kept an eye out for it - i do see certain riders riding with this style of leg.
Is it more dressage? My barn is hunter/jumper but also i know my trainers have a lot of dressage training. In fact, one day soon they are probably going to pop me in a dressage saddle because they say it kind of forces you into a good riding position.
I've been riding for about a year, w/t/c and some jumping.. but now that i can physically do these things and hang on, I'm going back and trying to refine my leg, seat, technique etc. Some days I just trot! I get the impression i will be in this 'phase' for a while. I try hard but no amount of trying makes it happen over night.. just gotta keep at it: heels down, ankles relaxed, no gripping in the knee, keep hips open, stretch long, keep calf contact on the horse, loosen my shoulders (where i keep tension), open my shoulders/boobs out, keep elbows in, close my hands (but not too tightly!), balance equally on both sides, equal weight, try and avoid chair seat w/ two pointing a lot... and above all else of course, RELAX, breath! lol. make it look easy so that when the new beginners come they don't realize how much work it is :) ha.
i love it though! :)
