Use revolving kettlebell handles on your dumbell for this exercise to give free wrist movement. Load the bells to 20 or 25 lbs. each. From the hang position as show, bend the hand on the wrist inward, slowly but forcibly, bending the elbow to get more action. Without a pause bend the hand on the wrist outward as dotted line shows, straightening the arm strongly. This is a progression of No. 17 and employs all the muscles on the outer arm with greater concentration on the frontal muscle.
