well i boxed for about 6 years, even boxed in front of about 1000 people in a fight called "tuesday night fights" at the Fat Cat, in modesto california....i did also train with weights but i never heard about it stunting your growth lol... then again im only 5'10" lol. we actually used to put 4lb weights that were made for ankles, on our wrists and hit the speed bag with them on. i boxed middle heavy so my weight was right around 203lbs usually but since then i stopped and pretty much do nothing, no working out, not even running any more.... im getting lazy in my old age lol
