What do the books say about isometric exercises in the context of fighting and how it contributes to the elements related to being able to move, withstand, and maintain joint, tendon, and ligament health? "The books" are just now learning about the benefits of Tai Chi and that the slow movement goes way beyond just building strength.
From someone that does a horse stance a lot and uses the horse stance a lot. I can tell you from first hand that this is not true. My original post even highlights that more goes on than "just a horse stance"
1st. That's not a horse stance and 2nd. As for what you are referring to. There's a different.
In terms of a horse stance, there is no need to push all the way up. Do you do full squat extensions with your legs when you spar or fight? or do you keep your knees bent for the majority of the time?
Show me the mechanics of a full range leg squat in this fight? Did it out number the times the fighters shifted in and out of horse and bow stance? Did they have strong stances or were they often trying to regain balance? How often did they have their legs straight with their knees almost locked out vs them having their legs bent.
