I have just joined and am excited to get going. However, looking at the layout of videos I am very confused as to how to navigate through the site. 

I thought there would be some kind of structured playlists e.g. beginner, intermediate, advanced weekly routines or similar in some kind of set order. I have done a search for all three levels but still nothing kind of follows on from one routine to the next. It seems a bit all of over the place. Am I missing something? Anyone have any suggestions as to how to best find my way around? Thank you. 

Also, I just a small edit. I had a quick look at one video and there is no warm up. Are we meant to do some kind of warmup prior to, and cooldown after? Any help with my questions would be much appreciated thank you.
