Step back and sink, kettlebell racked tight on your shoulder.
Stay tall and braced, don't let the racked weight pull your torso forward.
Stepping backward keeps your front shin vertical and your weight planted through the front heel, which drives the work into the quads with the glutes stabilising and finishing the stand. The racked bell sits on one side, so your trunk has to fight a constant pull to stay tall while the legs do their job. It earns its place as a knee-friendly lunge variation that sneaks in anti-lean core work with every rep.
Stepping back keeps the front shin more vertical and loads the front leg without the braking forces of stepping forward, which most people find kinder on the knees. It is also easier to stay balanced with a bell racked on one side.
Both setups are useful. Racking opposite the front leg fights your trunk hardest, racking on the same side loads the leg more directly, so pick one, do all your reps, then swap and keep it even.
Lower until the back knee hovers just above the floor, or lightly kisses it. Cutting the depth short robs the front quad of its hardest range, going down under control matters more than speed.
