This Woodway EcoMill treadmill is eco friendly where you not only exercise but also you generate enough electricity to power the treadmill. You don’t even have to plug it into the socket(wall) and use even more energy. 

While you’re exercising it charges the battery and then in turn keeps the display up and running.It does this by utilizing Woodway’s near frictionless drive system. This may not be a good option but you can add it to your ‘gym collection’. It allows you to work out indoors and keeps things eco-friendly. This is good news.

But the bad news is, it is a bit costly which some people may not be able to afford it.  It costs around $8500 available in colors black and green.
