This product is designed for sitting exercises to strengthen the biceps. It allows the user to extend and flex the arms up from the elbows while using handgrips on two separate levers. A weight stack will create resistance and is easy to adjust. It can handle arm curls and can work for all body sizes. It allows the user to perform alternate and standard arm curl exercises in the proper way. The independent arms also make it easy for the elbow and shoulder joints to be exercised correctly. The cam design also results in an appropriate load curve for uniform support. This includes two user interface options to make it easier for weight parameters to be adjusted as required.
