Exercise machine with arm handles and slider steps bought by my daughter and now taking up space in our basement. It works manually for sliding of the feet, and it is a good workout for your arms and for general aerobic movement. It has some electronic connections, which control the monitor for time, distance and calories burned, and I do not have the connecting wires. It works without the electronics. It is easy to use for a general exercise and to increase range of motion for arms and legs.
