Decision

Which should you choose?

The Barbell Lateral Lunge lets you load the heaviest weights and progress in small, steady jumps. The One Leg Squat 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 glutes adapting.

Common questions

Is the Barbell Lateral Lunge better than the One Leg Squat?

Neither is universally better — both train the glutes as the primary mover. The Barbell Lateral Lunge lets you load the heaviest weights and progress in small, steady jumps, while the One Leg Squat needs no equipment and scales through leverage, tempo and reps. Choose based on your equipment and which movement you can progress consistently.

Can I do both the Barbell Lateral Lunge and the One Leg Squat in the same program?

Do the Barbell Lateral Lunge and the One Leg Squat work the same muscles?

Yes — the primary muscle is the same (glutes) and both rely on the same supporting muscles: quadriceps, hamstrings and calves.
