I've owned a handful of Latin dance fitness DVDs, and this is a nice break from those. The footwork is less complex, it incorporates more arm and upper body moves than most Latin dance DVDs, and it's all low-impact (so it may not be intense enough for intermediate exercisers). There aren't as much traditional Latin dance moves in this as in others - there are more aerobic dance moves. That said, the aerobic components are refreshingly original, without the usual tired, boring morass of chasses, grapevines, and knee lifts. (There's even a quick little move where you pretend to play conga drums.)
You won't need any equipment, but you'll need enough front and back floor space to be able to walk about 4 big (or 8 small steps), and enough space on the sides to take 2 big steps in each direction.
The warm-up and cooldown blend smoothly into the workout itself, so on the downside, there's no menu other than "Play" or "Resume." And if you're looking to learn traditional Latin dance steps you can take to your cousin's wedding, you'll be disappointed.
Overall, it's sexy, playful and fun, and easy to follow with plenty of cuing.
