I think that 8 years are enough to become a good boxerI guess I'll reply in english as well as of now so we won't get no more problems. Anyway you say you teach boxing do you have kids in there that might have a future in the sport? I myself always was a Muay Thai fan but now that I got older I guess my need for fly kicks has gone and I have become a fistfighter. What would you say, as a trainer, is the right age for starting to box, 16,17,18,? How long does it take to become a good boxer?
