Which should you choose?
The Barbell Thruster lets you load the heaviest weights and progress in small, steady jumps. The Dumbbell Arnold Press 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 delts adapting.
