This is a primary exercise for the Pectorals (chest muscles). Many people prefer this exercise to the standard Bench Press because if offers more stability for people new to exercise.
Steps
Adjust the machine so that you are sitting with the bars at chest height.
Place your hands on the bars and place your feet on the foot rest.
Press out, extending your arms as far as possible in a steady motion.
Pause for a moment and then return slowly to starting position.
