Which should you choose?
The 3/4 Sit-Up needs no equipment and scales through leverage, tempo and reps. The Standing Wheel Rollerout loads the core through a long, controlled range. 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.
