I'm a beginner, just had what was probably my 7th lesson. I'm having a terrible time keeping the horse I ride on the rail of the arena. She just won't listen to my leg commands! I know she understands them because I can do the leg yield drill, and I can keep her out on the lunge line, not to mention she is older and well-trained.
Is it a problem of my form, which I admit needs a lot of work, or does she just not see me as the boss? I try very hard to get the form down but my muscles and balance just aren't there yet. I know form is part of it because I also have trouble not bouncing in a sitting trot (I think this is a result of needing to keep my heels down more and strengthen my inside thigh muscles). I am also a non-assertive/shy person so I am not sure where the issue is coming from.
I am trying to keep optimistic but it's frustrating me, and today I rode with someone on his second lesson and he definitely out-performed me on all accounts. I am determined to get this right so I can enjoy riding. Does anyone have advice?
