Seated Leg Curl/Extension

Dual-Function Integrated Design, Balanced Development of Thigh Muscles

The Seated Leg Curl/Extension features an integrated dual-function structure, enabling quick switching between leg extension and leg curl modes without equipment replacement, greatly boosting training efficiency and saving floor space. The leg extension mode targets the quadriceps, using a fixed-path motion to isolate and intensify the front thighs, shaping full lines and enhancing knee stability. The leg curl mode focuses on the hamstrings and glutes, with a controlled curling range to tighten rear thighs, improve flaccidity, balance muscle strength, and reduce injury risk. One machine covers anterior and posterior thigh training, catering to shaping, strength gain, and rehabilitation—ideal for beginners, pros, and rehab users.

OTC Welding Technology, Heavy-Duty Steel Frame, Commercial Stability & Durability

The main frame adheres to strict commercial standards, with key stress parts adopting OTC Welding technology for uniform, firm welds free of virtual joints or burrs, delivering excellent impact and fatigue resistance for long-term stability. The frame uses 150×50×T3mm oval steel tube, and the moving arm uses 80×40×T3mm steel tube—sturdy enough for heavy loads. The surface features automotive-grade electrostatic powder coating for rust, sweat, and corrosion resistance, maintaining a fresh look in humid gym environments.

Precise Weight Adjustment System, Full-Level Adaptability, Smooth & Quiet Operation

Equipped with an enclosed precision steel weight stack supporting 2.5kg micro-adjustments, with smooth gear shifting to match all training levels—from light shaping and rehab to heavy strength gains. The transmission uses 7×19 high-tensile steel cables and PA pulleys with precision bearings for smooth, jitter-free motion with consistent resistance, perfectly matching muscle contraction rhythms and maintaining constant tension.

Ergonomic Premium Configuration, Dual Comfort & Safety Assurance

Features high-density ergonomic cushions with high-resilience PU foam and wear-resistant synthetic leather, conforming to thigh and hip curves to reduce fatigue. The linked seat/backrest adjusts for different heights, keeping the spine neutral and lowering lumbar strain. Multi-position adjustable tibia and thigh pads stabilize the body, preventing compensatory movements and enhancing safety. Premium materials balance comfort, texture, and durability.
