The Tunturi Platinum PRO Air Bike is a unique bike. While using it, you are able to vastly improve your physical conditioning and work your upper body muscles such as your biceps. The handles make the Air Bike suitable for training your biceps by pushing and pulling the handles up and down. To make it tougher on your arms, you can put your feet on the foot supports in the front of the bike and only use the handles. The fan will start moving once you start cycling, which will create air resistance. The Air Bike has a diverse set of programs available to make your training more challenging. These are easily activated on the monitor with LCD screen.
