Okay, I'd have to admit I may have exercise ADD if there is such a thing. I am always on the look-out for new routines or types of exercise that keep me interested and challenged. This routine is for those that have mastered the basics first. This is much quicker paced than the first video, but again, the moves are well cued and are like taking a dance class. There is lots of repetition as you build the patterns and then create the whole routine. Burn calories? Oh yes, you will definitely burn calories. I work out every day, whether it is a dance work out, cycling, Tae Bo, Power Yoga, Pilates, and this made me sweat and kept me moving. I loved the music and the fact that her instructional segment is on a different part of the dvd, so I don't have to go through that every time I work out. I just cut right to the routine. Lisa is obviously a gifted teacher as well as a dancer and her moves are accurate and sharp, keeping good posture and alignment. If you are looking for a bit of a challenge, and love dance-based work-outs, I would give it a try. I am definitely always watching for her to come out with new dvds as I always know I will get a routine that works me out, makes me sweat and goes by quickly since her choreography is so fun.
