Wrist Rotations with Straight Bar

Hold a barbell with both hands and your palms facing down; hands spaced about shoulder width. This will be your starting position.

Alternating between each of your hands, perform the movement by extending the wrist as though you were rolling up a newspaper. Continue alternating back and forth until failure.

Reverse the motion by flexing the wrist, rolling the opposite direction. Continue the alternating motion until failure.
