Dumbbell biceps wall curl

Instructions

Stand with your back against a wall, knees slightly bent, arms extended along the body with a dumbbell in each hand with an underhand grip (palms under the handle). Your upper arms should be against the wall.
Raise the dumbbells to the level of your shoulders. Only the forearms move: the elbows, the upper arms and the back stay against the wall.
Slowly move back to the starting position, but do not stretch your arms completely.
