Remove the locking pins and assume a push-up position.
The body lowers into the push-up position and the rails are pushed out as far as the tension allows. The rails return to the deep push-up position and the body is pushed up to the starting position.
When the torso touches the rocker, the feet can be positioned on a stepper behind the machine.
Place the legs on an unstable surface, e.g. an exercise ball, to intensify the exercise.
