  Hexagon barbell bar is mainly used for fitness exercise, the general weight is about 20 kg. Like a normal lever, it can add different weights of barbell pieces at each end.

  The hexagonal barbell bar has a hexagon in the middle with grips on both sides. In use, the user stands in the middle of the hexagon and holds both sides of the grip with both hands, which is suitable for hard pull training. Helps to exercise the body shape, increases the strength.

  Compared with traditional barbells, hexagonal barbells are very suitable for beginners or people with insufficient physical activity. When the hexagonal barbell is squatting, the barbell and the users center of gravity are overlapped, so the flexibility of the body is not required, and the difficulty of the movement is relatively low. In addition, the use of hexagonal barbells on all parts of the body pressure is relatively uniform, more safe.
