I found Cathe's videos about a year ago and fell in love with the videos. I have hardcore extreme, pyramid upper and lower body, bootcamp, imax 2 and the new series. I wanted to know if anyone could recommend some videos for my next purchase. I like very intense cardio. I also do weight workouts several times a week. If anyone could give me any suggestions that would be great. I wish I could buy them all....Maybe over time I will have the entire collection. thanks everyone.
