The invention provides a multi-purpose barbell bar with the adjustable handle angle. The multi-purpose barbell bar comprises a connecting rod, handle bases are fixedly arranged at two ends of the connecting rod, the two handle bases are arranged in parallel, bearing rods are arranged on one sides, far away from the connecting rod, of the two handle bases, the end parts of the two bearing rods arefixedly sleeved with hanging plate sleeves, hanging plate limiting holes are arranged in the side walls of the hanging plate sleeves, handle bearing bases are rotatably arranged in the handle bases, handles are fixedly arranged on the handle bearing bases, a shaft sleeve is rotatably connected to the middle of the connecting rod, and a lifting ring is fixedly arranged on the side wall of the shaftsleeve. For the multi-purpose barbell bar, through the structures of the handle bases and the handle bearing bases arranged between the bearing rods and the connecting rod, the rotation of the handles is realized, during training, the wrists of a trainee can be subjected to angle adjustment according to the different training movements, thus the wrists can not bear the force deviating from the movement direction, with the manner, the training comfort, training efficiency and training intensity are improved, and meanwhile, the risk that the wrist is injured is effectively reduced.
