Back muscle trainer
Back muscle trainer
[Model]: GYX-L20A-1
[Specification]: 951 x 740 x 992 (mm)
[Instructions for Use]: Stand facing the machine, grasp the handles on either side with both hands, press your abdomen firmly against the upper abdominal pad, and place your feet between the dual‑layer footrests beneath the machine. Then, cross your hands behind your neck or interlace them behind your back, and perform downward bends and lifts, alternating the exercise repeatedly.
[Main Features]: It enhances the tensile strength of the back and abdominal muscles and ligaments, strengthens the coordination among the small muscle groups of the back, and increases the mobility and flexibility of the back muscles, thereby effectively improving the endurance of the back musculature.

Product Description
[Main Technical Parameters]:
◆ Direct-buried type; the upright posts are made of national-standard galvanized steel pipes with a diameter of 114 mm and a wall thickness of 3 mm.
◆ The handrail employs a tube‑reduction technique, tapering a 42 mm‑diameter tube to 32 mm in diameter to facilitate the installation of the handle sleeve. This approach ensures excellent structural integrity, an aesthetically pleasing appearance, ease of fabrication, and long‑term durability.
◆ The backrest panel is stamped from 4-mm-thick cold-rolled steel, ensuring an 8-year service life; the perimeter features R2 rounded corners to prevent personal injury. The foot‑plate crossbeam has a diameter of 48 mm and a wall thickness of 3 mm, with anti‑slip treatment at the double‑foot‑contact area, and soft end caps installed at both ends, in compliance with applicable standards.
◆ The equipment nameplate is made of stainless steel, secured with pop rivets, and its edges are tightly fitted against the upright post to prevent snagging, scratching, or other damage.
◆ The equipment has undergone relevant static load and stability tests in accordance with the GB 19272-2024 standard and complies with its requirements.
◆ The entire machine has no snagging, crushing points, shearing points, or pinching hazards; all apertures and gaps comply with the GB 19272-2024 standard.
◆ The equipment features a one‑station exercise position and is intended for single‑user operation only.
◆ The embedding depth of the equipment upright shall be no less than 500 mm, and the underground dimensions shall be no less than 500 × 500 × 600 mm.
◆ The components are cut using a laser cutting machine, ensuring high efficiency and precise positioning. For the bending process, a CNC pipe bender is employed, delivering accurate angles and an aesthetically pleasing finish. Prior to welding, all parts undergo degreasing to ensure that no oil or contaminants remain on the surface. Welding is performed with a CO₂‑shielded arc welder using a mixed gas, resulting in clean, smooth welds that require no post‑weld grinding. A dust collection and treatment system is installed to purify workshop air and safeguard worker health. Surface treatment utilizes shot blasting, providing thorough rust removal and enhancing the adhesion of the powder coating. Electrostatic powder coating follows a two‑coat application process: first, an epoxy‑rich zinc‑based primer is applied, followed by a green‑friendly, environmentally safe exterior powder coat. Imported electrostatic spraying equipment ensures uniform powder distribution and strong adhesion, yielding a coating that is resistant to acids and alkalis, moisture and heat, aging, and corrosion, while maintaining an attractive appearance—ideal for humid conditions and areas prone to acid rain. The coating formulation contains no toxic elements. Powder recovery is achieved through a cyclone‑type centrifugal separator, with a recovery rate of up to 98.6%, reducing material waste and minimizing dust pollution. The system is easy to operate and promotes energy efficiency and environmental protection.
◆ The equipment is packaged in a double-layer system, effectively preventing impacts and scratches during transit, ensuring the equipment remains undamaged.
