12. Barbell Back Squat
Using a barbell when squatting helps to engage the core and yield better results. The barbell back squat is one of the most common exercises seen at the gym as you can challenge your legs and go heavy. If your form is incorrect, this exercise is dangerous. If it’s done right, it improves overall strength and core stability. Your knees go beyond your toes, and you round your back. When your back is rounded, the barbell rests on your neck rather than your muscles. You go so low that your knees give in. Your heels lift, and you fall forward.

Set up a bar on a squat rack so that you can step under the bar and rest it on your back behind your shoulders. Pull your elbows back, and squeeze your shoulder blades together. When you contract your shoulder muscles like this, the barbell will rest on them instead of on your neck. Once the barbell is resting properly, step away from the rack. The barbell should be in line with the middle of your feet. Set your feet between hip and shoulder-width apart and sit your butt back into a squat without lifting your feet, letting your knees buckle, or arching your back.
