hmmm so monkey bars with 40-60lbs load. That's really impressive and something you have to actually train for.
I guess they did train that movement specifically (in armor etc.), because it's not something you could just randomly do on a whim even if you are very strong. Definitely not something you would WANT to do on a whim if you can fall down to your death and also have to be in good enough shape after to fight (which makes this particularly crazy).
Damn, considering that they were also trained grapplers, those must have been one hell of sparring partners.
So without legs? Just pure hands?
