Forearm wrist roller tube

Train forearms and grip with a rolled weight

Tie a cord through the middle hole, hang a weight plate on the other end and roll it up and down with straight arms: the square 34 mm tube with rounded corners and textured sides works the forearms and grip far harder than any squeeze ball.
