The motion stair 500 med simulates the daily activity of "climbing stairs". The intense and isolated workout concentrates mainly on the gluteus muscles and can be very effective. The motion stair 500 med has an independent step system and offers a handlebar design that allows free climbing as well as an arm supported workout. The step height and speed can be varied by each individual. The Auto-Weigh System constantly measures the weight of the user to calculate wattage and calorie display more accurately. The large comfortable footplates, the flywheel and the V shape drive belt ensure a unique motion step and a very smooth workout.
