I could do it 40 years ago with a M-16A1. I aint as limber as I once was but, with the aide of the post, the kneeling at 200 shouldn't be a problem.
Should be but that kneeling technique on the video with the left knee down is "unorthodox." I'd call it the "kneeling when you've got a post to lean on" technique.
Good thing they put the video out and you can practice like that.
