One bell racked, one side loaded, your core fights to stay square.
Resist leaning toward or away from the bell. Stay stacked and even.
With one kettlebell racked at the shoulder, every knee drive becomes a fight to keep your torso square against an offset load, which is exactly the anti-lean work your core is here for. The shoulder holding the rack works isometrically the whole time, while the quads and glutes power each march. It earns its place as loaded carry training you can do on the spot, building the trunk stiffness that transfers to squats, presses and everyday lugging.
Lighter than your press, heavier than feels comfortable to hold. Pick a bell you can rack cleanly for the full time without your torso bending toward or away from it.
The load sits at your shoulder instead of in your hand, so the lever is higher and the tilt is harder to resist, and the marching knee drive adds a balance challenge a walk does not.
Hip height, with a brief moment of control at the top of each drive. Rushing short choppy steps turns it into a jog and lets the core off the hook.
