The total workout is 45 minutes long, but it's broken up into 3 sections if you only want a short session.  It runs at a nice pace - the weight loss name is something of a misnomer.  You do a pose, and have time to sink into it a bit, but not so long you're shaking.  There are 4 different instructors to watch (and you can close-up on any of them at any time) depending on what your flexibility/strength level is.  The disk also has a ton of bells and whistles that I will probably never use.

5 stars out of 5.  I'll be using this DVD a lot in the future.
