Barbell Back Squat- Position the barbell on the back of your shoulders, and grasp the bar on the sides. Shift hips back, and lower yourself down so you are parallel to the floor, or your hips are fully bent. Your chest should be up, and your back kept straight. From the bottom position, extend your knees and hips to bring yourself back up to the starting position. Repeat for desired repetitions.
TRAINING TIP: Make sure to squeeze your glutes throughout the entire movement.
