Difficulty: Moderately Challenging
Step1
Choose a weight that is going to work for you. The lower the weight on the assisted chin up machine, the tougher the exercise is going to be. Choose a weight that is lower than your body weight in order to benefit from the exercise.
Step2
Grasp the parallel bars overhead and stand or kneel onto the weighted platform. Your palms should be facing each other as you hold onto the bars.
Step3
Lower yourself slowly until your arms are fully extended. Keep your arms and back flexed throughout the movement.
Step4
Lift yourself back up to a starting position as soon as you have lowered into a fully extended position. Pull yourself up until your chin comes up to or above the bars.
Step5
Repeat the motion for the desired number of repetitions. The more of your body weight you are lifting, the lower number of reps you need to do for a thorough work out.
