ActiveLife Trainer is protected by several international patents, including in Germany, the US, and China. One patented feature that’s unique to activeLife Trainer is the office-chair connection plate with its four openings.
But why is this necessary? Isaac Newton’s Third Law of Motion states that for every force, there is an equal force in the opposing direction. Applied to exercising on a mini elliptical or mini bicycle, this means that if you push your feet against it - which you’ll invariably do when you use it - the machine will push back at you with an equal force. If you sit on an office chair with wheels this means that as soon as you use such a mini machine, in no time at all, you’ll find yourself propelled across the office and away from the exercise machine. But how about if you just use a chair with legs, or maybe an office chair where the rollers can be blocked? Even in those cases, after just a few minutes, you’ll push the exercise machine, the office chair, and often both out of position because they are not firmly connected. If you can’t connect the exercise machine and the chair, pretty much the only other way to avoid this annoying problem is to bolt chair and machine to the floor - hardly practical.
But by hooking one of the office chair wheels into the connection plate, users of activeLife Trainer avoid this common problem because the chair securely and firmly connects to this mini elliptical to allow hours of healthy and trouble free daily use
....and that’s what those four openings in the connection plate are for...
Of course at any given time, you’ll use only one opening - which one will somewhat depend on the length of your legs and is largely a matter of personal preference. Finally, the top opening also makes a great handle to roll activeLife Trainer in and out from under your desk or around the office … for example in case your office mates want to give it a try.
