Anyway, the legs one is 60 minutes, and the other two are a little shorter, 52 minutes or so. There's also a separate chapter of 15 minutes of core. There are also some great premixes--like 3 total body workouts and I think some short on time premixes. It's pretty versatile. I just posted an all Amy rotation on my blog that uses a lot of Slo-Mo workouts: http://fitnessfig.blogspot.com/2007/12/amy-bento-rotation.html
