Lol I like this question. I’m gonna have to go with LaRue and say the vibration training machines that “all the celebrities” use. They are passive training devices that look like a big scale. You stand on them and they shake you like a road worker at different settings. However, I think Karin’s wins the most out-there award.
I was asked to try out and then videotape any exercises I could make up for a piece of equipment that was in the demo phase. Imagine a standard 4-inch aerobics step, then cut it in half and put hinges on one side so that it folds and clamps shut. Put a handle on one side so you can carry it like a suitcase. Attached inside the unit are several strengths of tubing and springs and some handles that you can extend outwards from the platform. So, you open up the unit and set it flat, pull out the tubing, then you can stand on it, sit on it, and do a variety of resistance exercises from the ground up. And when you’re done, you can fold it back up and it’s “portable.”
Price point was about $300.
Did I mention that it was 22 pounds?
When I think portable, I think (a) lightweight and (b) simple. This was neither. It also bothered me that the tubing was attached to the unit, which really limited the possibility for movement.
I wonder if it ever went into production.
