I'm just going to say say go put on some blue jeans a shirt and jacket and work boots. Go run or walk up stairs and do some exercises. Then quickly change into basketball shorts a tee shirt and sneakers and to everything again. You can tell the difference in weight and how more flexibility your are. This is why the rules on the armor is what it is. Yes any1 can put on plate but if your not uses to it you won't be able to move around as easily as if someone trained in wearing it is.
