The Discovery™ Series Selectorized Line Seated Calf Extension allows easy access and enhanced ergonomics for a precisely targeted resistance workout for the calf muscles. The curved foot platform provides a stable and comfortable foundation throughout the complete range of motion.
The linear bearing horizontal seat platform is easy to adjust and provides an effective position for all users. The seated position ensures that users direct force properly through their hips.
The center loaded footplate provides more even resistance on both feet, resulting in smooth movement and decreasing stress on the machine components.
A curved platform accommodates all users and stabilizes the ankles to properly activate calf muscles during the exercise.
Units have fully shrouded weight stacks in full compliance with ASTM and EN standards.
Each selector plate is entirely precision-machined on all surfaces. Top plate has replaceable precision self-lubricating bushings.
The plates feature a black painted protective finish. Guide rods are precision centerless ground, polished, with corrosion-resistant plating for smooth operation and rust retardation.
The weight stack is elevated to facilitate user pin selection from seated position.

Bolts are grade 5 or above in all applications.
The drink-and-accessory holder features large open, even surfaced area, easily accessable and easy to keep clean.
Glass-fiber-reinforced nylon pulleys for durability, with precision motor-grade ball bearing pulleys. Cable consists of 3/16 inch (7″x19″) aircraft cable coated with black pressure-extruded nylon to 1/4 inch or 1/8 inch and coated to 3/16 inch. The cables conform to specification MIL-W-83420D-BARE cable only. When used, redirection pulleys route cables close to frame to minimize chance of external interference.
The frame is 11 gauge (.120 in) 2×4″ electroweld steel racetrack tubing. Movement arms are made of electroweld steel round tubing. The five-stage material prep/wash process if followed by an electrostatically applied, heat-cured powder coat.
