I've always had weak ankles (I remember randomly having my ankle flop over when I was small), so I was wondering if this is something that could be fixed with more regular exercise...? It feels like it's in the tendons on the outside.
As for correct posture in the saddle, I've had problems keeping my heels down (I have a tendency to bring them up before take-off). I can pick up my stirrups again during the trot- maybe I'm doing it wrong and it messes me up...?
Any advice or exercise ideas is appreciated. :)
