A:Answer The treadmill can work without iFit. There is a manual mode available. HOWEVER, stay away from this machine if you will not use iFit. It DOES NOT have programmed workouts in manual mode, the speakers don't work in manual mode, you barely get any features with the manual mode. The specs mention an Aux Port to use the speakers with your own devices, but my treadmill does not have it. According to Proform/iFit support, the new version of this treadmill no longer has that port. Last, you cannot use the speakers via Bluetooth. Short answer is, if you are not using iFit, you might as well find a used treadmill for half the price and more features than this. I wish I would have known that before wasting my money.
