WHAT'RE UPDATED: First, we upgraded the steel tube to 2mm thickness to upgrade the strength of two lever arms. Second, we upgraded the length of the base frame to 60” to ensure the stability of the machine. Third, we upgraded the design of pulley holes and added a protective cover for the pulley to provide a smooth movement. BENEFITS OF LEVERAGE GYM: The use of lever arms creates the smoothest motion in any weight training machine and is the closest thing to free weights. Lever gym equipment offers a safe, versatile way to engage in strength training at home, providing the benefits of free-weight exercises with reduced risk of injury and without the need for a spotter.
