Place an Olympic barbell into a landmine attachment or secure it against a wall so it can’t slide backwards. Come into a half-kneeling position directly in front of the end of the bar. Grip the end of the barbell firmly in boths hands and hold it out directly in front of you with your arms extended. This is your start position. Maintaining a firm grip on the bar and keeping your arms extended, slowly move your hands to the left and down towards the floor. Inhale as you do so and keep your core braced throughout for stability. Aim to move your hips as little as possible. When your hands are level with your core, proceed to return to the start position slowly. Exhale as you do so. Repeat for the required number of reps (or time) on one side before changing to the other. Be sure to change your kneeling position when you alternate sides.
