Instructions

1. 1

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

2. 2

   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.

3. 3

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