this video has 3 sections, each 20 minutes long, with their own warm-ups and cool-downs. the toning section is good, though you won't always break a sweat. it does a good job firming up most of your body. the kick and jab will definitely get you sweating, though she probably doesn't really know what she's doing, and the whole "i've got your back" thing is redundant and kind of annoying. i just try and ignore it when she says that. as for the dance section, i watched it once and that was enough. too low-impact for me, but if you're a beginner, you might like it. i only use the first 2 sections, but i think they're great.
