Ah that is great!

With Jiujitsu, is it such a super cool thing to learn. I remember how scared shitless I was when I first went in for the intro class not knowing anything. With the White Belt Curriculum series, you can see the actual class and know there is nothing to be scared of.

I can't see ever stopping the training for all the fun, exercise, and powerful feeling you get.

I would make sure you have full range of movement and can kneel without pain before starting though. You can see some videos in the meantime though and that won't hurt.
