Start facing away from the landmine attachment with the end of the barbell resting on one shoulder against the base of your neck while leaning slightly back into the weight of the barbell.
Squat down with control while keeping the weight of the barbell as close to centered over your midpoint as possible, then drive through your heels to stand all the way back up and return to starting position.
Repeat for desired number of reps, then switch the side of your body the barbell is on every subsequent set.
