OMGosh. I preordered the DVDs in September. I've read the posts and couldn't bear to wait so....my best friend and I ordered the VHS series to hold us over. But wait -- I borrowed the Rhythmic Step DVD from someone over the holiday (I looooove RS) and finally got the courage to do Interval Max, which brings me to the point (finally). I could hardly make it through Interval Max! How will I ever make it through the new intensity series?!? Can anyone compare Interval Max with one of the new tapes? Yikes! Maybe I should use only one riser.
