S-014 Seated Leg Extension

Targeted Power. Precision Movement. Built for Longevity. The S-014 Seated Leg Extension is engineered for controlled, effective quadriceps training in commercial gyms and high-performance training facilities. Combining a reinforced steel structure with smooth biomechanics, it delivers consistent resistance, precise alignment, and long-term durability under heavy daily use.

Heavy-Duty Frame Construction

Built around a flat elliptical 50 × 150 mm steel tube weight-stack tower and a 60 × 120 mm oval elliptical frame, both with 2.5 mm wall thickness, the S-014 offers exceptional rigidity and stability during high-load training. This robust construction minimizes flex and vibration, ensuring smooth motion even at maximum resistance. Finished in durable powder-coated black or silver, the frame is designed to resist wear, corrosion, and constant commercial use.

Precision Training & Smooth Resistance

The S-014 isolates the quadriceps muscles with a carefully engineered movement path that promotes proper knee alignment and muscle engagement. A 5.6 mm high-tensile steel cable ensures smooth, consistent resistance throughout the full range of motion. The adjustable 80–120 kg weight stack allows progression for beginners through advanced users, making the machine suitable for a wide range of training programs.

Comfort & Adjustability

A slide-rail seat adjustment system allows fast, precise positioning for users of different heights, improving comfort and ensuring optimal biomechanics. The premium seat padding, available in black or brown leather, provides support during heavy sets while maintaining a clean, professional aesthetic.

Why the S-014 Stands Out

• Reinforced elliptical steel frame for superior stability
• Smooth cable-driven resistance with high-tensile steel cable
• Adjustable seat for precise user alignment
• Progressive weight stack for all training levels
• Designed specifically for safe, effective quadriceps isolation
• Commercial-grade finish and materials

With a 214 kg net weight and a compact yet solid footprint, the S-014 Seated Leg Extension is built to perform day after day—delivering controlled strength, comfort, and durability where it matters most.
