Which should you choose?
The Cable Assisted Inverse Leg Curl keeps constant tension on the muscle through the whole range of motion. The Machine Kneeling 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.
