Arm Exercise
When using the device for upper body exercise- it should be placed directly in
front of the user on a table top, and the user should be seated in a comfortable
chair such that they can easily reach the pedals without hyper extending (over
straightening) the elbow joint. This can be accomplished by either placing a
seat cushion on top of the seat or by moving the device closer to the user.
NOTE: Please use the Left/Right Handles (23L/23R) to do the arm
exercise.
