Side-step the dome, squat, stay glued.
Brace your core hard so the dome doesn't tip as you shift your weight sideways.
Standing on the dome and stepping one foot wide to squat splits the work unevenly, so your quads take the load through a stance that keeps shifting between stable and unstable ground. Your glutes control the sideways weight shift and drive you back up onto the dome each rep. It earns a place for building frontal-plane strength, the side-to-side control most squat variations never touch.
Almost everyone has a stronger side, and the dome exposes it. The anchored foot on the dome has to keep the platform still while the stepping leg squats, so the weaker combination shows up fast. Train both sides evenly.
It works constantly. Keeping the dome from tipping while your bodyweight shifts sideways is a stability job in itself, which is why this beats a plain lateral squat on flat ground for balance training.
Alternate. The steps have you return the foot to the dome and switch sides each rep, which keeps the rhythm going and trains the weight shift in both directions.
