Query: Poor quality, annoying instructor

This was filmed in a very dark studio with people who don't know the routines. Very basic moves with little direction. The instructor seems to be getting cues from behind the camera and then remembers to change the routine. She seems a little surprised to find herself leading a workout video and will suddenly scream out. I only keep it around for abs when my workout doesn't include my core.
