I started out with the firm also around 1998. I had the VHS tapes and collected several. Then I found out about collage video in 2001 and started collecting videos.(back then it seems there wasn't much on collage? I don't remember seeing Cathe on there then?) I ended up mostly doing the firm and tae bo with a few others. I even did denise austins workouts haha.
I didn't find out about Cathe from Collage though which is strange. I guess I quit checking the site a while but I found a VHS of Crosstrain Xpress- kickbox at a consignment shop and loved it. Then I just looked up the site and my first purchase was the preorder for the Intensity series DVDs. I now have a ton, they pyramid dvds, gym styles, kick punch and crunch, butts and gutts etc. they are all great!
I do think Cathe is the BEST also but I like to mix things up and also do Jari L, Amy B. I have my favorite old Firms on DVD but I can't remember when I last did them. I still bust out my urban rebounding dvd sometimes. I just do the advanced with J. B. I think rebounding is fun and I wish there were more videos for it. I can't get into Urban reboundings other videos.
I actually just donated my whole VHS workout video collection to goodwill the other day. I realized they hadn't been touched in years since I started collecting DVDs (and better workouts at that). Cathes are for sure my favs!
