Boxing Weight Classes

Boxing weight classes are a way of ensuring that boxers of similar size and weight are matched up. While one can argue that a true champion would fight anyone, fighting within one's weight class makes for better fights. Bigger boxers have more natural weight behind their punches. Heavyweights tend to inflict more knockouts but the fighters tend to be slower. Featherweights, on the other hand, are blindingly fast. Dividing up boxing into weight classes helped to reduce the number of lop sided victories and the ability of boxers to pick on smaller opponents.

It is not uncommon for boxers to move into and out of weight classes. As they grow older, they could move from middleweight to light heavyweight in order to challenge themselves more or to take a title in two different weight classes. Nothing says one has to stay in one class for one's entire career. If one can add or lose the weight, one can fight in whatever class one wants.

I just wanted to ask how do you know which weight class you are best in and how do you gain weight without adding fat.

If you want to gain weight without fat you need to hit the gym alot with protien shakes after (no creatine or weight gainer). But in Boxing you would want to lose weight unless youre up in the heavyweight division.

how do you lose the weight if your a bigger person

Im 150lbs, will i still be in the welterweight class when i do amateur?

Yeah welterweight is 152 max in the amateurs.

I am of 5 feet and 2 inches and wanna make my career in pro boxing. i am of 50 Kg in weight. that weight should be all right for me or i have to loose me weight??

Read this article on how to determine your ideal weight - should answer your question.

is the a weight limit on heavy weight? if so what is it because im 6' 6" and about 285lbs

Hey DHReid - it actually depends if you're talking professional or amateur boxing. Your weight isn't an issue - there's a class for you. Professionally you're a heavyweight, amateur - super heavyweight.

Anyways, I've updated the tables to make the distinction, so they should give you a better idea now. Cheers.
