thats a good idea. but, it wouldn't be far. not all gyms goes up to the same wights. some guys goes up to 150s others up to 250s. if your after powerlifting, and throwing up pressing overhead with super heavy weights. in that cases DB's would be harder and very uncontrollable. when you use a barbell you can control it easier. the main is, you can't get DB's heavy enough for these guys that can do bench 500lbs with no sweat
