Thank you for the feedback/advice. I tried the sequence of poses a few times last week and I was definitely sore but was not in pain. Some of the poses are not overly challenging but they aren't easy, which I feel is where they should be. I will do this sequence for a few months 4-5 times a week then go to an actual Ashtanga class as at that point I will have increased my strength, flexibility and endurance. The "not beginner" poses don't seem to be an issue for me, maybe I have natural strength and flexibility that I was unaware of.
Again, thank you for the replies.
