I just did PUB for the first time, and my muscles are jello! I've been doing MM (also have powerhr), but this w/o rocks! I also love that during the bicep section, Cathe and the other ladies seem to be having such a good time... really gets me motivated.
I just did this one yesterday and I have to agree with you - I think the crew is so relaxed and accessible in this one - it makes me feel like I'm part of the gang! And it hurts so good!
i LOVE the pyramid workouts.. helped me break through my plateau.. really got ripped when i added PUB.. i try to do them a few times a month mixed with muscle max and s/h
