At some time I would like to try Olympic movements but for now I'm just doing basic weight lifting movements: flat & incline bench pressing, military press, upright rows, deadlifts, barbell curls, bent over rows, squats.

Right now I have an old TDS bench however soon I will be buying the Bodysolid Power rack with lat attachment.

Even though I'm just going up to 425lbs., would a bar rated for 1200 or 1500lbs. 'hold up' better than a bar rated to 1000lbs?
