Which should you choose?
The Barbell Good Morning lets you load the heaviest weights and progress in small, steady jumps. The Lying Leg Curl Machine fixes the movement path so you can push close to failure with less skill 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 hamstrings adapting.
