The benefit of practicing dumbbells http://www.ericdumbbell.com

The benefit of practicing dumbbells 1, improve muscle control ability The dumbbell is only controlled by the hand. If there is no good control ability, like a compass, it turns East and West. So to maintain the direction and weight of the dumbbell, you have to learn to seek the assistance of other muscle groups, and muscle control can be improved. 2, solve the state of imbalance Because the weight of the dumbbell is optional. You can strengthen against the weak side; Or train with the weight that the weak side can afford until the hands are almost adjusted. However, the correction of non-hand is limited. After all, people's hand is still an advantage and it is not necessarily perfect.
