There are many options for biking at home. The easiest is called a “pedal exerciser”. This device is simply the pedal component of a bike which is place in front of a chair to allow the feet to comfortably reach and pedal. There is a resistance control knob which lets you adjust the tension of the pedal machine.

This is a great place to begin your fitness routine. It is fairly easy and can be done from the comfort of your favorite chair!
