While I think the 120 is a bit low, I have to commend barns that will set a limit. The wear and tear on a horses back is something many overweight riders simply don't want to hear, both in terms of their saddle fit, or the soreness issues the horse may be having.
And it could also be that by setting limit this low, they are avoiding the "I only weigh 10 lbs more" deal too.
And without seeing you of course I can't be sure, but is your balance badly off because of your weight. If you are 6 ft tall, and 169? Big difference from being 5 ft tall and 169 and your gait may show that?
Many variables here, as well as barn may have had horses ruined due to someone's weight and not be willing to chance that again.
And something else to consider is this.
They may have had such bad experiences with overweight riders they are simply not willing to deal with them anymore. What I am talking about, is the rider is not improving due more than anything else, to their weight.
They aren't posting, they are hauling themselves out of the saddle by the reins. Their weight issues ruin the saddles, since they are over the cantle and pommel, and the horses are sore backed after these riders are on them.
And those riders? 9 times out of 10 will reject any criticism about their riding, and refuse to do anything to correct it too. Or play the "oh you are mean" card when it is pointed out that weight does make a difference.
Not saying you are one of these, but the odds are very high that they have had people like that, and are simply avoiding it at all costs in the future.
It's just odd because I e-mailed them beforehand asking if they offered adult lessons to which they said yes. After doing some research I think the instructor I called was a youth instructor. So not sure who e-mailed me back, but it wasn't her.
I have since found a handful of places that will let me ride! Now I just need to arrange for a babysitter for my daughter so I can
For the record, here is a body shot of me from a few months ago. I've lost 10lbs since then. (I have been documenting my weight loss since I started at 210)
