Hammer Strength Iso-Lateral Leg Extension (MTSLE)

The MTS Iso-Lateral Leg Extension features separate weight stacks for independent diverging motion for optimal biomechanics. Start range adjusterments allow users to determine their own range of motion, and independent motions provide single-leg training variety.

  • Unilateral motion in a lower body machine is exclusive to Hammer Strength
  • Iso-Lateral motion provides a diverging motion, which allows better knee joint alignment for optimal biomechanics
  • Independent motion provides the added variety of training one leg at a time and is ideal for balancing
  • Standard start-range adjusters allow users to determine their own range-of-motion




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.
