Abstract

This utility model discloses a core training device, including a frame with a suspension assembly and a support assembly on it. The support assembly is located below the suspension assembly. One end of each of the two booms is fixed to the support assembly, and the other end is rotatably mounted on the frame. The counterweight mechanism includes an electromagnetically controlled damper. The frame has a rotating seat, and one boom is connected to the rotating seat via a rotating shaft. The electromagnetically controlled damper is drively connected to the rotating shaft. This training device adopts a vertical design, occupies a small area, and has a variety of movement trajectories, effectively training the human core muscle groups. Its resistance adjustment abandons traditional counterweights, using an electromagnetically controlled damper to achieve flexible resistance adjustment, improving the user experience. The reciprocating design of the counterweight mechanism provides a damping effect during crunches and relaxation, reducing the feeling of stagnation caused by sudden changes in force, making the equipment run more smoothly, balancing comfort and training efficiency.
