Which should you choose?
The Assisted Sit-Up reduces the load so you can own the movement before going unassisted. The Side Hip (On Parallel Bars) needs no equipment and scales through leverage, tempo and reps. 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.
