Very similar to barbell curls, dumbbell curls will exercise the biceps, forearms, and shoulders. The difference is that when using dumbbells, you will exercise your forearm muscles and oblique muscles more to keep your body balanced and upright.



  • Dumbbells have a larger range of motion, which can fully contract the biceps so that the full stimulation effect can be achieved!
  • More flexible: you can train with one hand, change the grip, and change the angle more!



  • It is isolateral or unilateral, which means you can only exercise on one side at a time
  • Carrying heavier dumbbells can cause muscle damage and increase the risk of injury

The most important muscle in the barbell curl exercise is the biceps on the arm. When performing the barbell curl exercise, most people have a certain understanding, because the barbell curl exercise itself is It is a single-joint action. When exercising, only the biceps of the arm can be exercised. Then we naturally use the biceps to exert strength and focus on this during the exercise. This is the most obvious move to exercise the biceps.



  • As far as weight is concerned, barbells can easily obtain large weights, which is also one of the biggest advantages of barbells.
  • The barbell is more stable. Everyone knows that the most taboo thing in the process of exercise is incorrect posture, avoid swaying and shaking. The body will inevitably shake with heavy dumbbells, but if you use a barbell, the whole body will be relatively stable.
  • From the perspective of force, using a barbell can exercise the arm with less strength (usually the left arm is weaker). If you use a barbell, this problem can be solved and promoted. The strength of the left-hand increases.



  • The position of the wrist is a bit unnatural when the barbell is curled, which may cause wrist pain
  • Due to the pole, the range of motion is limited.
