Query: Not for beginners!

As a beginner, I found this video difficult to keep up with - the pace is extremely fast and the movements are too advanced for someonme just starting out. I would recommend the fitness video "Callenetics" for beginners. By the way, the guy in the second part of the "Fat Burning" video looks dazed and confused - that alone speaks volumes.
