What will make my body better at taking punches in boxing?
As you get more experience you will learn to move with punches, and how to hold your body so you can absorb the shots. It really is pretty much a matter of experience, but you’ll get the hang of it as you spar in the gym. You can build tolerance some by doing extra core work to harden the muscles, but it’s mostly just experience. As for the weight thing, in the United States bouts are only sanctioned between people who are close to the same weight. For people under 16 there are age groups as well as weight classes to consider. You may be able to get some fights with bigger guys, but as you move into competition you will find that the 147 and 156 weight classes are very common all the way to the adult ranks. You shouldn’t have a problem finding competition.
