I have a TB and a Message Therapist for him, and a Chiro - never heard of that. I grew up riding and training TB's and I've never stretched their legs before I rode. If you want to stretch your horses legs, fly at her.
A horse strengthens their tendons and muscles, by doing proper and correct dressage work on a daily basis. Majority of GP riders spend 6 days a week doing only that - and that is what builds up their flexion and and everything else. Not jumping on a daily basis.
What breaks down horses, is when a rider thinks jumping is the be all and end all of their daily riding. Proper conditioning is the key to prevention and preservation.
Daily hacking is also extremely benefitial. Builds a well rounded, well physiqued horse - with less likely to injur itself.
Proper educated riding is what prevents a horse from pulling muscles, hamstrings and tendons.
Beautiful horse Spyder!!!
I think the key to not having your horse break down in addition to that. Is stretching. My physical therapist stressed to me how much it is necessary. If you look at a mri of a horse that has been stretched and a horse that has not you can see the difference. On the horse that hasn't you see lots of scar damage on the horse that has been stretched all its life you see alot less.
Warmup. vs. Stretching
Much of this confusion comes from a misinterpretation of research on warm up. These studies found that warming by itself has no effect on range of motion, but that when the warm up is followed by stretching there is an increase in range of motion."
