Which should you choose?
The Barbell Lateral Lunge lets you load the heaviest weights and progress in small, steady jumps. The Flutter Kicks need no equipment and scale 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 glutes adapting.
