Thank you for all your tips and suggestions everyone!
I will try all of these!
She's a great horse, just too smart for her own good! Haha
I'm just going to have to lunge her and tire her out before I get on.
Her buck isn't horrible, I'm just worried about falling (I got thrown into a fence a while back and cracked a rib) don't want anything to get worse!
She did much much better when I rode her today!
No buck at all! I just walked her in a round pen, changed directions, and worked around some cones and she did great! And I only lunged her for about 10 minutes before the ride!
Just needed some good conditioning!
