Now rotate the wrists. Perform these same two maneuvers with an underhand grip. With the barbell version of this you will hold a barbell, first overhand then underhand, arms tight against your sides. Curl the wrists up and down. Guitarists to strengthen the fingers for playing have used the wearing of finger weights in routine activities.
Weighted gloves accomplish a similar fete.
The wrist roller uses a dowel, rope and weight plate. You hold the dowel out in front of you, arms straight. You roll the dowel, lifting the weight with the rope as it twists around the dowel. Roll the weight all the way up and down again. In a reverse barbell curl you curl the barbell up backward toward your chin and back down again.
