Dumbbell Extension with Pronated Grip

Lie on a flat bench, holding a dumbbell in your hand. The arm is straightened up and perpendicular to the body. To perform this exercise, use a pronated grip: the palm is facing forward, towards the legs. Place the other hand on the biceps of the working arm for support, as shown in the figure. As you inhale, slowly lower the dumbbell down. As you exhale, straining your triceps, return the dumbbell to its original position, straightening your arm. Perform the required number of repetitions and change hands.
