My horse is about 16.2 hands tall, and I am a mere 5' 3". I cannot mount him from the ground. My mom is an inch shorter than me and she can. I weigh 185 lbs and I'm not very flexible. I am actively losing weight, I lost 25 pounds last year and hope to lose at least another 20 this year. But, I'm not sure what the best exercises might be to improve my strength and flexibility for mounting. I would so love to not have to depend on finding a rock or tree stump to use to mount.
I'd love to hear what helped get you off the mounting block/fence/rocks and mounting from the ground!
