Which should you choose?
The Barbell Standing Back Wrist Curl lets you load the heaviest weights and progress in small, steady jumps. The Dumbbell Lying Pronation works each side independently and demands more stabilizer control. If your gym has both options, neither is a wrong choice: pick the one that feels strongest through a full range, and swap after 6 to 8 weeks to keep the forearms adapting.
