That is, the user inserts a selection shaft into the selection holes of different counterweight plates to achieve load adjustment. During exercise, the user uses a steel cable to lift the counterweight plate along a guide rod, thereby achieving the purpose of strength exercise.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0021] Referring to Figures 1-3 , a counterweight structure for a fitness device with bidirectional acting force, including a main spindle body 10 and a main rotating disk 1. Threaded connection holes are provided at both ends of the main spindle body 10 for convenient connection with fitness equipment. The main spindle body 10 is rotationally inserted into the interior of the main rotating disk 1. Rope fixing disks 4 are provided on both sides of the main rotating disk 1 for winding ropes. The rope fixing disk (4) is connected to the main rotating disk 1, a right bearing mounting mechanism 6, and a left bearing mounting mechanism 5 through a locking mechanism 3.
