The design solves the problem of the overloadresistance torque which can lead to the apparatus using inertia and producing noise when training and it can lead to the muscles fatigue too.
Stand-oriented Overload Protection to automatically balanced serrated resistance, effectively extending the service life with a saw.
导向支架过载保护，能自动均衡锯齿阻力，有效延长锯带使用寿命。
