Review title: Not for beginners but does the job
Product review: My co-worker and I had a hard time keeping up with this. It's definitely not for beginners, but if you are able to keep up it's a good 20 minute work out. Even though my co-worker and I couldn't keep up, it had has sweating within the 1st 10 minutes! I would suggest warming up before starting it because the instructor goes immediately into the workout w/out warming up.
