Place one end of a barbell into a landmine attachment or securely into a corner. Hold the barbell in the Zercher position — arms bent, bar resting in the crook of your elbows, close to your chest or held in place with hands just above chest level. Face the landmine and stand with feet hip-width apart, core braced, and chest up. Step one leg diagonally behind and across your body, lowering into a curtsy lunge. Keep your front knee in line with your toes. Lower until your back knee hovers just above the ground. Keep the bar stable and elbows tucked under the bar. Drive through your front heel to return to the starting position. Complete all reps on one leg before switching, keeping the movement smooth and controlled.
