4 days and I won by knock out I would not recommend this to anyone. It was a different time back then . I had , had a million street fights so I was ready to fight.I have seen guys with no training just get up and get in the ring and win.

2 years

I trained two months before my first match, but depends if you're ready and you want to you can very quickly in the ring.

But it is best to train 2 months and you have a lot of sparring and then go into the ring.

It depends on you

I haven't had one yet but I've seen guys go anywhere from 2 days to 2 years.
