Trademarking is only for a brand name, like Pepsi, Kleenex, or xerox. You notice it's not patented. It's funny the devices that have patent numbers are fakes! (look this up if you want, it comes right up in google) Like I said earlier, someone has taken an existing concept, packaged it and promoted it with some slick marketing and voila, a new "Amazing Fitness System"! I don't have anything against things that get people moving and working out, and that appears to be effective - but I am always fascinated by the marketing machine and how well it a) convinces people they have something new and b) separates them from their money.
