Gravity: Coming to a gym near you

Gyms are full of machines and equipment for every type of workout and exercise you can imagine. If you're looking to burn calories and get in shape they'll all do the trick, albeit some faster than others.

All those machines are there to cater to all of our differing preferences when it comes to working out, and hence the industry never stops working to come up with new ways to get the same job done. The latest is the "gravity machine," and if one makes an appearance at your gym will you try it? Because it may not be that long before you have the option, if you don't already. They're rapidly getting floorspace and even becoming the center of various fitness classes, and although I've never used one people who have seem to love them.

Thoughts? Opinions? They look like a backwards leg press to me...
