thank you so much for your answer! you could be absolutely right, as we have tried many bits and nothing seems to be happening. i do jump her in a running martingale, and a flash in hopes to help. i typically try to sit back (as she always pulls the reins from my hands) and lift my inside rein, but i will definetly try your way. thank you so much for the advice!
It might not be the bit that is the problem. I would consider using a running martingale on your horse is tends to help a lot with horses who have a tendency to be heavy on the forehand. If your horse is heavy on their forehand becuase they take the bit between their teeth I would consider a flash noseband. When your your horse is rlly leaning on your hand I would try this- when they start to lean pick your outside hand straight up a couple inches away from where you hand it and return it to where it was before, while simultaneously adding your outside leg. I know it sounds confusing on here it’s something you would kind of have to see but, imagine doing a half half but doing it straight up in the air ( make sure you only lift your hand a couple inches) when you do this, it will shift your horses weight onto their hindquarters and it will help them push from behind instead of dragging from the front. Hope this was helpful!
