I've been working out with The Firm for over 20 years. I love Firm, and this Trasfirmation Cardio Weight System is no exception. This kit stores the weights and DVD's into a convenient and easy to store space - you can fit the whole thing neatly inside a dresser drawer. The DVD's were made in about 2007-2008. Each DVD is different and interesting: One DVD for sculpting, one for cardio, one with Aerobic Weight Training, and etc. You never get bored. They also vary the instructors. You can be beginner, intermediate, and advanced. If you're a beginner, you just use lighter (or no) weights. They always show low impact modifications, for example, if you have bad knees, and can't jump. These DVD's can work for everyone. They are also sold seperately, if only one or two interests you, but I like to have them all, since I get bored easily. I like the variety. The instructors of the Firm give flawless cues and execute the moves perfectly and with proper form, as always. The production quality and music quality are high, as always. Even though these DVD's are older, I still enjoy them!
