Decision

Which should you choose?

The Bodyweight Incline Side Plank needs no equipment and scales through leverage, tempo and reps. The Ghd Sit-Up 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 abs adapting.
