What Madonna is working out on

First off, not a catchy name. This is the kind of thing that's like the band Billy Joel mentions in Still Rock N Roll to Me: There's a new band in town but you can't get the sound cuz it's only in a magazine. I doubt most people will ever get to see one of these contraptions, but it sure sounds cool.

My simplified interpretation of how it works is - like moving in water. Reading for biomechanical sense from a trainer's viewpoint, I think it sounds logical and sound. Reading as a gym equipment buff, at $6K a pop and designed for one person to use for a long time at a time, I think it sounds like something only the very rich will see, in private studio situations. Maybe in a few years they'll launch a Gyro Shuffle...

From the site
"Unlike most conventional exercise machines where linear or isolated movement patterns are performed creating uncoordinated strength, the patented GYROTONIC EXPANSION SYSTEM® emphasizes multiple joint articulations without compression, thus strengthening ligaments and each attachment. The motion patterns are natural, turbulence free and pure with no interruption, creating a bridge between contraction and extension through the rotating movement of the joints, resulting in a balanced support system for the skeleton."
