Which should you choose?
The 3/4 Sit-Up needs no equipment and scales through leverage, tempo and reps. The Weighted Hanging Leg-Hip Raise adds external load to a bodyweight pattern for direct overload. 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 abs adapting.
