[Dumbbell bent over one-arm row] exercises the back muscles and biceps. Support the palms and knees of one side on the flat plate, keep your back straight, and tighten your abdomen. The other hand holds a dumbbell hanging by your side, and straighten your legs to support the ground to keep your body stable. Inhale first, then move the right elbow joint back and up against the body, but not beyond the torso, and exhale at the same time; when lowering, try to stretch the back as much as possible, inhale at the same time, and repeat~
