I have some experience with zen monasteries in the West. It's generally considered very unlikely that you'll be able to sit for over an our on the ground without significant pain arising unless you're unusually flexible or grew up sitting like this. Forcing yourself to sit for long hours can be good for your practice, but it can also lead to injury.
