These are the best years to begin to train boxing.Can be amateur and pro world champion several times.I know some who have started with 22 and now is a good pro boxer.How old are you is not important,The important thing is do you have desire to Succeed.

good luck and never give up ;-)

You are correct there are many very good professionals who started boxing at a much older age than 14.

sergio martinez started at 22

If he's got the natural talent then of course

I've told him plenty of times that he can be very good because there has been many fighters start even older then him. But he insists that I ask more people and I want other people's opinion.
