Which should you choose?
The Barbell Thruster lets you load the heaviest weights and progress in small, steady jumps. The Smith Rear Delt Row fixes the bar path so you can push close to failure with less balance demand. 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.
