Which should you choose?
The 45° Side Bend needs no equipment and scales through leverage, tempo and reps. The Landmine 180 lets you load the heaviest weights and progress in small, steady jumps. 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.
