See I was going to make a post about using the magic seat. Everyone says that the actual velcro on your pants is very thin (not wide) and it wont even hold a kid on if they get really unbalanced. It isnt to HOLD you in the seat, it's to keep you in the center and keep from bouncing or sliding. I was going to get one for my son and his mini, just bc his feet don't reach the stirrups well.
HOWEVER! I started considering it for myself. First, I have pelvic misalignment and tilt. Which means (with myself), that my right side of my pelvis (bc your pelvis is actually two pieces) is lifted up (about an 1 1/2") above the other side AND tilted forward 1 1/2"). I was born with this, and as my doctors never figured it out and treated, resulting not only in an unbalanced pelvis, but one leg being shorter and scoliosis and although it doesnt effect anything my ribs stick out in on one side. I'll even show you a picture of that maybe....
So what I have now is a seat that is very difficult for me to maintain (I believe), and a constant problem with the right stirrup slipping off my foot (which usually leads me to falling off if the horse shifts quickly when this happens, and not quiet getting the right looking seat. My butt looks likes it's popped out (even more so bc I have a big butt lol). I have rode daily in the summers and I feel I should be farther along, but even my horse friends are starting to wonder about the effects my pelvis is having on my riding. They not my spine is slightly curves (it's just how it is) and it look like I'm leaning. Which I'm not. I even had a friend take a picture from behind while I trotted and drew a line up my horses spine, and up my back. You can see my spine curve, but my neck and pelvis look in balance.
So my riding abilities include walk, trot, canter, spins, I do barrels, poles, cones, and everything else at the fun shows. I ride bareback fine, and have even stayed in the seat bareback when my mare spooked and did that 180 spin away from an outdoor AC unit. I lost a stirrup around a third barrel, and didnt have it on the canter back. I may have fell if she spun.
I used to fall off alot more, when they were green, but they arent anymore. I don't fall off anymore, but when I loose my stirrup I get scared. I usually get it back, but I'm usually panicking until I do. We have tried fixing so one stirrup is higher than the other, but it makes me feel off balanced. I'm wondering if I even just put on strap of velcro on my leg. I have been told to put rubber bands on my feet, but it scares me too, lol...
I didnt mean to hijack this thread. But I was wondering the same thing. I wear a helmet, bc I have had multiple concussions. My horses are farther along in their training now and do very well. I'm wondering if the seat will help me, or if it will make me to reliant on it. And will it break loose if I really go fall off? I WANT it too! I have heard Martha Josey uses them. I have seen others use them. Never seen anyone fall off... I don't know, lol.... I AGREE that you should NOT use it to keep yourself of a horse that is green or may buck or rear (ESPECIALY REARING!!!!), but it may not be a bad option for a problem with seats. I would want my son to eventually not need it.
Your horse may be rough, but he may always be rough, lol... I think you should try to sit the trot or even post it if it's really bad.
