The arm extension machine works the arm muscles, specifically the TRICEPS.
The seat is specifically designed anatomically to support the spine and improve form. Smart pins to gradually increase the weight load integrated into the top of the weight stack which allows you to select an additional plate that is half the weight of those in thein the rest of the stack.
INDEPENDENT ARM EXERCISES
Exercise the arms either unilaterally or bi laterally (one arm at a time or both arms together). The handle design has been designed for any forearm length and makes the machine less sensitive to elbow/axis alignment.
This feature allows variable resistance to be delivered to accommodate the specific strength curve of the muscle group being trained. As a result, you’ll perceive consistent resistance throughout the entire exercise.
