Place an Olympic barbell into a landmine attachment or secure it against a wall so it can’t slide backwards. Stand tall with your feet hip width apart and toes slightly turned out. Grip the end of the barbell firmly in both hands and hold it directly in front of you, resting just above your chest. This is your start position. Keeping your core braced, bend at the knees and drive your hips back and down. Lower until your thighs are parallel to the floor or deeper depending on your range, making sure your knees are pointing in the same direction as your feet. Then in one smooth motion, extend the knees and hips to drive yourself back up to standing. As you reach standing, push your arms and the end of the barbell away from you, driving through your shoulders until your arms are fully extended. Perform the sequence again for the required number of reps (or time).
