I think it’s fun to learn both, and then will have more skills and greater appreciation for other styles of riding and what they are trying to accomplish. I started out a competitive hunter rider (10 yrs), then turned dressage rider (>20 years). Tough transition for me from “perched” to “sitting, feeling horse, with leg relaxed, on horse, under me”. I just couldn’t do it in the beginning, since h/j seat was second nature. Now, I’d call h/j equ perched not feeling the horse (other MMV), and dressage equ actually sitting on the horse, feeling and communicating all parts of its body. When I did HJ, I had no concept of a horse being crooked or where their body parts were (YMMV). Having ridden a few very well seasoned, retired, national level hunters in lessons after surrendering to dressage >20 years…they felt so stiff all directions, hollow and crooked compared to my dressage horses. And unresponsive to dressage aids (of course). I think they just wanted me to sit there, do nothing and let them do all the work.
I competed training thru FEI >18 yeaars, now retired from competition for most part. Dressage position is second nature to me. I still jump occasionally, but I now look like a dressager trying to jump…still trying to be particular about my equ, crest release, leg under me (but I don’t like to ride with super short stirrups now), but no longer perched hunt seat equ on my crotch like I did back then (was zone hunt equ champ), (if I was jumping 3’ courses, I’d probably fall off :winkgrin:)…I can now feel my entire horse. My leg is straighter, on my horse, not toes turned out, gripping calf, heels crammed down.
The part where your instructor said “legs ahead of you” might be because she didn’t know what other words to say?? Dressage, like hunters, have foot directly under the body. Only difference is knees are just bent much more in h/j. Shorter the stirrup, greater the knee bend, more difficult it is to sit in the saddle, so more perched on crotch. Mechanically impossible to keep straight from ear to foot with short stirrups, and really sit butt in saddle. Legs would almost have to go forward. In either riding style, if foot goes too far back, upper body falls forward, and entire leg slides behind. In either style, if foot goes too far ahead of you, you are in a chair seat, upper body goes back as legs go forward.
When I ride dressage or h/j, I am still balanced. My foot is still below me, but difference is length of stirrup, which regulates degree of knee bend. Leg is never ahead. I’d feel really wrong and off balance.
Hard to say if you were a slouchy hunter rider, without pictures.
I’m guessing your’e a beautiful hunter rider. I love that you want to learn dressage and new skills.
