Decision

Which should you choose?

The Barbell Straight Leg Deadlift lets you load the heaviest weights and progress in small, steady jumps. The Machine Lying Two-One Leg Curl 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.
