I joined a gym with great classes, and so I haven't used The Firm in ages... BUT, I LOVED it when I used it -- in fact, one of the reasons I joined a gym was my old VHS copy of my fave Firm workout (Aerobic Workout Volume One with "Master Instructor Susan Harris" on the cover in that AWFUL yellow 80's leotard) was getting so damaged from overuse you could hardly see the picture anymore! It's a killer workout - even when I was really fit it still kicked my butt!

I got a replacement copy off of eBay just in case I ever need it - I'd swear by that workout alone. I used it and jogged in the park on alternate days for a month or more several years ago when i didn't have $$ for a gym, and looked and felt great! I did eventually get bored with doing the same workout over and over, but it was such an all-over workout that I couldn't complain about the results.

I don't know anything about the new ones they have out, but I will always be grateful to Susan Harris and her ugly yellow leotard for being there when I needed them!
