EXERCISE BIKE

if you are looking for a good way to burn calories, lose weight, or just something to keep in shape, upright bikes are the way to go. 

 indoor cycling bikes have a weighted flywheel which is connected to the pedals through a transmission system that closely resembles that of a real bike. You can adjust the resistance via a knob, like you would change gears. These bikes also allow you to pedal while standing up, which gives you a much more intensive workout and engages different muscle groups. 

make sure that your weight isn't above the maximum user weight
