1 - Set up a landmine attachment on the floor and load one end of a barbell into it. Stand facing the loaded end of the barbell with your feet in a wide stance, significantly wider than shoulder-width apart.
2 - Pick up the end of the barbell with both hands, holding it at chest height with your arms slightly bent. Keep your chest tall and core braced throughout the movement.
3 - Shift your weight to one side by bending the knee of that leg while keeping the opposite leg straight and extended to the side. Your toes on the straight leg should point upward as your heel stays on the ground.
4 - Descend into a deep lateral squat on the bent leg, lowering your hips toward the heel of that foot while keeping your torso upright and the barbell held close to your chest. Keep your knee tracking in line with your toes.
5 - Pause briefly at the bottom of the movement, feeling a deep stretch in the inner thigh of the straight leg and the glutes and quads of the bent leg.
6 - Push through the heel of the bent leg to drive yourself back up to the starting wide stance position, maintaining control throughout the ascent.
7 - Repeat for the desired number of repetitions on one side before switching to the opposite side.
