Due to the high stability of the barbell, the weight of the training can be a little larger. On the contrary, the weight of the common dumbbell in the gym is only 50kg.
Although the barbell is more stable than the dumbbell, this will also become a limitation. Taking lying push as an example, barbell lying is more difficult to fully
contract the pectoralis major muscle; On the contrary, the use of dumbbell lying push can increase the moving distance to a greater extent, allowing the muscles to contract completely.
It is better to train between the two so that the muscle stimulation is more comprehensive.
