Hi, all. :) I'm new to the forum. Just found it today, even!
I lovelovelove this topic. I am 6'0" and 270 lbs. I spent my life in the suburbs with working parents who didn't have the extra $$$ to send me to riding lessons. At age 22, I am finally able to branch out and do what I've always wanted. I've been trail riding a few times, but I'm also taking proper western pleasure riding lessons. (I volunteer at the barn in exchange for the lessons. I've dropped from 285 lbs after I started going! Who needs a gym?!)
I am surrounded by petite, slender, and athletic ladies when I go to the barn. I feel like I'm the size of a small pony when I get on one of the horses. It's really embarrassing, and I've never been more self-conscious! The owner/instructor is a really sweet lady and notes that "we're all equal here."
I definitely feel like I could ride better if I were lighter. Being fluffy is somewhat tricky when it comes to climbing into the saddle.. or even trying to get into/out of the loft.
I'm so happy there's a section for this on this website. I'll be watching!
