When rowing with one-arm dumbbell, there is no restraint of barbell bar, and the range of activities becomes larger, so the stimulation intensity to latissimus dorsi is also obviously increased. Especially for students with waist injuries, rowing with one-arm dumbbells is definitely much better than rowing with barbells, because rowing with one-arm dumbbells has multiple support points and less pressure on the waist. At the beginning of exercise, I always insisted on paddling with one-arm dumbbell, but like many beginners, the method was incorrect, greedy and vain, and I gained weight, but I didn't feel anything in my back after exercise. Because many people do this action in an incorrect way, they don't feel anything in their backs after practicing, and finally choose to give up like me.
The correct way is to keep the core tight first and breathe with abdomen (belt is recommended). Then, try to keep your body stable. Don't lean down sharply when putting down the dumbbell, and don't lean up sharply when lifting the dumbbell. At the same time, the elbow should not be too far back, and the arm and back are almost parallel. If the elbow joint is too far back, it will cause the shoulder to be too far away from the body, leading to the humerus moving forward, which will do great harm to our shoulder joint.
