The novice exercise method does not recommend the use of heavy objects. Many people blindly pursue a large weight to practice muscles, but they don't know that they can't control that weight, which leads to the use of the strength of other muscle groups to complete the action, thus making the action irregular and the effect greatly reduced.
First, bend with a small dumbbell to isolate the biceps brachii, so that the biceps brachii can be deeply stimulated without the help of other muscle groups.
