How old does one have to be to begin training for boxing?

My son really wants to begin training for boxing, but is only 8 years-old. Is this too young? Also, does anyone know how much this costs?|||any age really , i started at 18 iknow that the most you should be willing to pay is between 40-60 bucks per month, 8 yrs old is not too yound all thats says is by the time he reaches 14 he`d probably be ready to compete in the jr olympics with continual hard work, 17 or 18 the world championships and the olympics if thats were he wants to go|||wel i do kickboxing and ur son is 8 and i no people hoo started at 4 and it would probaly cost like 80 bucks a month and make sure ur kid is tough :)|||there is no set age for how old one must be to learn how to box. when learning anything starting at a young age is an advantage. 8 years old is a great time to start to learn. this certainly doesn%26#039;t mean h will fight at this age but starting to learn young is the best way to learn b/c when he gets older he will have an advantage over others who did not start young. as for how much it costs that depends on the gym you send him to. the one I belong to is $150 for 3 months. other gyms will have their own rates. for a good boxing gym go to amateurboxing.com and tell Melanie Ley about your son and how old he is, she will be able to find you a good gym with a price you can afford.|||any age. and see how much it costs some are free some cost so just check with the manager. i am 11 boxing. and even is you had a 4 year old child he could box so yea
