The MG Series Rotary Torso is a powerful and comfortable device that provides users with an effective way to strengthen the core and back muscles. The kneeling position design is adopted, which can stretch the hip flexors while reducing the pressure on the lower back as much as possible. The uniquely designed knee pads ensure the stability and comfort of use and provide protection for multi-posture training.The main advantage of this machine is that you can handle heavier weights due to the guided execution. You don't need to hold the weights in your hands, which eliminates the need for stability training and allows you to focus more on your side abdominal muscles. However, this means that your core muscles receive less intensity or even no training at all.
