Let me start by saying that I am a HUGE fan of Billy's workout dvds. This one, however, was a big disappointment. I didn't even break a sweat. My heart rate barely made it above 100. If you cut out the endless talking he does, it'd be about a 30 minute workout and 10 minutes of that is the supposed 'warm up'. Like other reviewers, I stood around wondering what to do while he jabbered on. Owning other Billy workouts, this one is going straight back. If I paid to go to a session as poor as this, I'd be wanting my money back. Billy needs to either get back on track or come up with something new, or just leave it be now. He has some excellent workouts out there, I shall be sticking to those in future.
