I got this DVD yesterday and I've only had the chance to do the floor workout section (there are two 15 minute routines, one standing, one on the floor). It was absolutely killer! I've been working out with a trainer since January, and regularly do the 8 minute abs DVD, I'm in decent shape, but this takes my abs workout to a new level. I loved it and can't wait to see the results. If you are looking for something more hardcore than what you are used to, this is a great choice.
