If you like the "knees over toes guy" exercises, I'd definitely recommend signing up for his online coaching program for a couple of months. The Youtube videos are a bit scattered and there are some nuances to the progressions that don't come through very well, plus the feedback on your form is helpful when starting out.
I also started from the Youtube videos but I got a lot more out of it after I started doing the full program with coaching.
