Comments and tips
Pull with your elbow, not with your biceps.
Keep your torso near horizontal and your elbow tucked in.
Do not rotate your torso as you pull the dumbbell upward.
Many people think that the biceps acts as a synergist in rowing exercises such as the bent-over dumbbell row, when, in fact, it acts as a dynamic stabilizer, along with the long head of the triceps brachii.
The bent-over dumbbell row is great for developing unilateral upper-body strength.
As with all unilateral exercises (exercises that allow you to train one side of your body at a time), start with your weak side, and do not perform more reps with your strong side. This will allow your weak side to catch up.
