Query: Work up a sweat with 12-40 second routines? Not!

I bought this DVD because there were only 2 other exercise DVD's in existence at the time. "MTV" seemed to imply a vigorous "youthful" workout. I'm 47. I didn't even work up a sweat. The first 30 minutes revealed routines lasting from 12-15 seconds, repeated only twice. The last 5 minutes consisted of four 40 second routines. This is not what I call aerobic exercise. Save your money! Shame, MTV!
