I got this DVD as a bit of dancey fun to go alongside my more hardcore workouts (Davina, Nell McAndrew etc), and for this reason I wasn't disappointed. Robin Antin (scary looking American dancer/choreographer type) and her perfectly toned dancers take you through three workouts - Don't Cha Workout, Burlesque Workout and Buttons Workout (Don't Cha and Buttons, as you might expect, are dances to the Pussycat Dolls' songs of the same name). Each workout also includes a 'Breakdown' section so you can do this and learn the moves first before putting them all together in the full workout.
Upsides - the dance moves are broken down well and aren't too difficult to learn - if you've perfected any of the Ministry of Sound DVDs you'll probably nail them on the first try - and they're also a lot of fun, although Robin and her dancers do tend to take themselves quite seriously (this in itself is something to have a laugh about, especially if you're doing this in a group!)
Downsides - you only learn one dance sequence per workout, which you then repeat for the duration of the song. If you're new to dance workouts this might be a good introduction, but there is a risk of getting bored if you intend to do this workout every day, besides which one song isn't a long time to be working out for. Robin also screams instructions all the way through the actual workouts which ruined the impact of the songs for me...she'd have been best off saving her shouting for the breakdown sections (but horses for courses I suppose!)
There is a 'special feature' on the DVD in which Robin tells you about all the famous people she's worked with in the past as well as how she got into dancing and choreography, but I found this a bit boring and rambling. Certainly don't expect to be hearing any juicy gossip, or indeed anything, from the Pussycat Dolls themselves!
On this note, if you were expecting to be led by Nicole from the Pussycat Dolls, I'm afraid you'll be disappointed - she makes a brief appearance in the 'Buttons Workout' section, huffing and puffing her way through the moves (she must have been putting that on for our benefit!), but doesn't say much at all. The workout is very much led by Robin. I didn't mind this as I'm not actually a huge PCD fan, but I might well have been disappointed otherwise, especially as the DVD is very much marketed with Nicole at the forefront.
In short, buy this if you want a bit of fun and are looking to pick up some dance moves, but if you're looking for something that will actually get you working hard and out of breath, try something else!
