|Utility:||Basic or Auxiliary|
Sit on seat. Grasp handles and place back of upper arms parallel on padding with elbows approximately in line with lever's fulcrum.
Push lever down until arms are fully extended. Return until forearms contact upper arms. Repeat.
With heavy resistance, back pad will need to be adjusted to keep torso close to arm pad. Adjust seat height, so back of upper arms rest on padding. If seat is too high, shoulder will need to rise near end of extension to complete final range of motion since forearms will make contact with pad before lockout. If seat is too low, range of motion will be compromised because elbows will not be completely flexed at beginning of movement.
If machine has secondary lever (as shown), elbows do not have to be exactly aligned with primary fulcrum. Also see Lever Triceps Extension on alternative apparatus.
