im 6ft 1(and growing) and about 150 pounds.. im thinking of taking up boxing. Would it be a lot more beneficial if i gained some serious strength and mass b4 i did because im basically a twig now..the men in my family though have all been "late bloomers" and pretty big.. after they finished growing. In last two years i've gone from 5'4 to 6'1 and im 17. My grandfathers brother was a professional boxer to..
