The Power Twister bar is excellent for working both the upper and lower portions of the pectoral muscles, as well as the biceps. There are several movements you can do to isolate these muscles. It's important to maintain disciplined control with all movements, never compromising the exercise with excessive speed or lazy form. The Power Twister bar is not adjustable; therefore do only the number of repetitions you feel safe performing. Exercise routines are only suggestions based on average performance. It's up to you to add or subtract sets or repetitions according to your body's capabilities.
