Selecting the right cardio machine for you will depend on many factors.
If you do not know what type of machine to get, we suggest an upright spin bike with good build quality but minimal electronic features. You should make sure to buy a device holder for your phone or tablet, of course!
If you know you want an elliptical or treadmill, we suggest finding one with high marks for build quality. The cheaper versions of these machines can wear out and cause you to face very expensive repairs down the line. We advise you to not worry about electronic features and instead focus on quality of construction. You can use your smart device + BitGym for the entertainment and motivation!
If you know you want a rowing machine, we suggest a water rower with the tablet arm extension.
