I workout with a personal trainer 2x/week, walk/jog 2-3x/week and am always looking for a DVD workout to fill in the blanks. This DVD is perfect. On the days when I do this workout, I use the elliptical then select the 15-minute total body workout.....THAT'S RIGHT, A 15 MINUTE TOTAL BODY WORKOUT! I've been very happy with my results overall. I loved the 30 Day Shred DVD but developed low back issues after doing it every day. I've had no such issues with this DVD. Jackie is very conservative with her movements and stresses form over reps. Her cueing is perfect even if she gets annoying by claiming every exercise "...is my favorite. I could do this all day." Overall, I like her style and love the DVD.
