Hello Everyone, I am new to the forum

I have started lessons again after a 12 yr gap!! I have picked up the posting trot great but I CANNOT get the canter down. I keep losing my balance in the saddle and I actually fell off during my last lesson

My question is this, is there anything I can do when I am not cantering to help with my balance or is the only way to get the feel is to just keep cantering....Please help, it just looks so darn easy when I see everyone else canter and it is so frustrating

Thanks!
