Begin by standing with your feet hip-width apart and holding a barbell at one side of your body, with your palms facing your thighs.
Keeping your core engaged and your back straight, bend at the hips and knees to lower the barbell down towards the ground.
As the barbell reaches the ground, use your legs and glutes to push through your heels and extend your hips and knees to raise your body back to the starting position.
Repeat the movement for the desired number of reps, then switch sides and repeat the exercise with the barbell on the opposite side of your body.
Kneel down facing the landmine with your knees hip-width apart and your back straight. Grasp the landmine barbell with both hands, interlacing your fingers and holding it above and slightly in front of your body.
Keeping your core engaged and your back straight, twist your torso to one side, rotating your arms and the landmine along with it. Pause briefly at the end of the twist, feeling the contraction in your oblique muscles.
Slowly rotate back to the starting position, then twist to the opposite side, repeating the same motion.
Repeat both sides of the rotation for the desired number of reps.
