Barbells and dumbbells look very similar, and many people think that the difference between the two may only be a bar in the middle. In fact, this is not the case. There are indeed some differences between barbells and dumbbells. General coaches say that barbells are more suitable for helping the body exercise and increasing muscle latitude and strength, while dumbbells are mainly used to help exercise small muscle groups in the body and help reshape muscles. In short, if you want to exercise well, you can combine the two.
The use of barbells limits the distance the arm can be extended, allowing for a significant amount of weight, which generally means greater stimulation to the muscles. So generally speaking, barbell bench press uses a large amount of weight to increase chest muscle strength or thickness.
Dumbbells belong to biaxial instruments and are relatively flexible. Pushing up a dumbbell requires more auxiliary muscles for stability, so it is generally difficult to push a dumbbell horizontally with a greater weight. And dumbbells, due to their flexibility, can lower the elbows deeper, pull the chest muscles longer, and do more work. They can shape and stretch the chest muscles, enhancing auxiliary muscle strength. Moreover, biaxial instruments can provide a more balanced strength, which can be used to balance the development of muscle strength and enhance the weak side.
If you are more specific, the weight is more intuitive. Generally, many people use a push down method when exercising, while using a barbell push down can achieve a weight of 100kg. However, using a dumbbell for the same push down can only produce 50kg. This is a clear difference, so you need to choose a barbell or dumbbell according to your own needs.
