Stand upright holding a kettlebell overhead with one arm, keeping your elbow locked and core braced. Step forward or backward into a lunge while keeping your torso upright and the kettlebell stable above your shoulder. Lower your body until both knees are bent around 90 degrees, with the back knee close to the floor. Push through your front heel to return to the starting position. Maintain balance and avoid leaning or letting the weight drift out of alignment.
