Which should you choose?
The 3/4 Sit-Up needs no equipment and scales through leverage, tempo and reps. The Band Seated Twist gives accommodating resistance that peaks at the top of the 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.
