Dude this is a question only you can answer it’s asking your thoughts on it :|
What doesn't limit the range of moton from the things which you've mentioned would be age. Age per se doesn't really limit the range of motion - while there are factors which negatively influence our range of motion and which are strongly correlated with age, it is hard to say that age itself would be the cause of a limited range of motion.
All of the above is the correct answer
Endurance is the answer i think you're looking for.
