What would you do?

I am a far worse rider on the left rein than the right. On the left, I bounce to the canter and my horse doesn't go so well for me.
Any tips which I could incorperate into my daily hacks or schooling?

Start playing left handed tennis(!) and carry your waterbuckets/anything heavy with your left hand instead of your right. Also cycle and only have your left hand on the handle bars- this will all help make your left side stronger and balance you muscle mass, which will help you to ride more equally

Pilates, tell the instructor of the problems you are experiencing and they will be able to devise additional home exercises for you to develop body symmetry.
