I am a group ex instructor and I taught for Greg at the Hip Hop Club in Alaska!! I was there the day they shot the video..Those were my friends and I LOVED them all!!!..YES...It was 1987....THE clothes were horrible and yes...HE did have a "curl," but who cares. If you took the SAME exercises today and did them in class, which I sometimes do, you will see that they are effective and they are hard. Now that we are all so much more educated and we have core training and sport specific training etc....sometimes getting back to the "basics" of lots and lots of reps and different angles is a REFRESHING change!They waited for years to review it and raked it over the coals and I thought it was very unfair, and yet today it's STILL a favorite....Get over the clothes and the hair and the music and get a great workout....LOL!!:)Have fun!!
