Aerofit AF 5118 Alternate Leg Extension
Aero Forge Series · Plate Loaded Strength
The Aerofit AF 5118 Alternate Leg Extension is a plate loaded leg extension machine from the Aero Forge Series, Aerofit’s heavy-duty plate loaded line, built on over-sized frames with multi-link motion and knurled grips. It trains the quadriceps. Users extend each leg independently against the shin pad, so every rep follows the same safe, repeatable path.

How much floor space does the AF 5118 need?
The machine measures 57 × 75 × 51 inches (L × W × H), about 145 × 191 × 130 cm. Allow extra clearance around it for loading plates and moving safely.
