1. Constructed from high-quality British-standard steel tubing (114 x 55 x 3mm) and high-precision welded pipes, the frame exudes a sense of strength and substantiality. 2. The product features a one-piece, integrally molded polyurethane foam cushion; its balanced firmness ensures a stable training trajectory while remaining comfortable and durable. The seat, backrest, and round pads are composed of high-density PU foam and upholstered in premium 1.2mm-thick leather, available in a variety of colors. 3. The seat adjustment mechanism utilizes a rubber-mounted locking system, offering a convenient, rapid, and highly secure method for positioning. 4. Manufacturing employs high-end international production processes—including laser cutting, automated robotic welding, and precision CNC machining—to ensure fabrication meets the most advanced industry standards. 5. The rust removal (sandblasting) and electrostatic coating processes work in tandem. The paint finish involves a multi-stage treatment: immersion-based pre-treatment, full-surface phosphating, and electrostatic powder coating. A specialized dual-layer coating process—including a protective glaze finish—is applied to ensure both the aesthetic appeal and corrosion resistance of the equipment. 6. Guide Rods: Ø20mm solid steel rods, treated with an anti-corrosion coating and polished to ensure smooth operation and prevent rust. Cables: Self-lubricating Ø5.8mm steel cables are utilized. 7. Targeted Muscle Groups: Primarily targets the leg musculature. After selecting an appropriate resistance weight, the user engages their leg muscles to perform calf raises, thereby effectively exercising the lower leg muscles. 8. Weight Plates: Constructed entirely from steel. 9. During the workout, the load force is transmitted through the hips to the body, effectively eliminating direct pressure on the spine. The adjustable backrest accommodates users of various body types.
