Query: Wish I could return it.

I was so excited to get this DVD based on the back cover. The first workout I did was the INTERVAL one and I was sorely disappointed. The workout is 20 minutes long and the first 10 minutes of the workout are all knee lifts. Nothing but knee lifts for about 10 minutes. Then when they introduced the first "interval" I barely noticed because my heart rate didn't even go up. It was more knee lifts which are very damaging to the tendons.Secondly, I did the other cardio workout on the DVD and it was stale, stale, stale kickboxing. You know, jab, hook, uppercut. Again my heart rate barely went up.I wish I could return this DVD and next time I see a SHAPE DVD I will rent it from the library and then consider buying it.
