The MTS Iso-Lateral Triceps Extension features separate weight stacks that provide independent diverging and converging motions. Pad and seat adjustments provide neutral wrist positions and optimal body placement.

  • Angled pads and handles positioned to allow for neutral wrist poistion
  • Seat height adjusts for user height and upper arm length
  • Iso-Lateral motion allows for equal strength development and provides great variety for muscle stimulation




Dual selectorized weight stacks preserve the integrity of independent arm or leg action, allow users to obtain more proportionate results, and add more strength-training variety to workouts.


Iso-Lateral® technology delivers the smoothest converging and diverging arcs of motion in the industry. This allows users to move both limbs at the same time, one at a time, alternating, or with different weights for each.


Short, direct transmission of resistance through a belt-drive system ensures smooth performance and premium durability.
