The Pedal Exerciser is an easy to use item for home exercise and enables you to enjoy upper and lower body exercise from a seated position; pedals can be moved forwards or backwards and the resistance can be adjusted with the top adjusting knob. Use your feet in the pedals to exercise your legs, hips and buttocks, or rest the Pedal Exerciser on a table and turn the pedals with your arms for an upper body workout. Requires no external power supply.
