I am of the opinion that anyone who can squat 400 lb below parallel without a suit or press200 overhead has a strong core. I am of the opinion that when a person increases their squat, theyhave increased their core strength. I am also of the opinion that if a person wants to strengthentheir core, they must make something quantifiably stronger.
