The cardio trainer consists of two pedals and a simple hydraulic mechanism with two cylinders that allows you to exercise on the spot by transferring the weight of the body from one leg to the other simulating walking up stairs.

To get the most out of the OBS306A, we recommend maximising core engagement by alternating your steps just short of a full depression on each pedal this means pulling your leg back up just before you reach the bottom of each step forcing you to engage your abdominals to balance and help you work up a pulsing rhythm.

The LCD monitor counts your time, steps, calories and reps/minute, it runs on a replaceable AAA battery (included).
