20 years old is definitely not too late, I made this video for older guys but it applies to you as well -
No dude, it's cool, you'll lose fear of fight, and you'll build yourself, I don't mean it's cool to lose fear of fight, just for defence. 20 it's not old at all. 50 would be.
One is never too old. And, if you don't give it your best try, you'll never forgive yourself.
No good luck
I don't want to become a professional, I know I'll never be able to but is 20 to old to even start boxing classes? I love boxing and I've wanted to atleast do boxing lessons for a while now but I have a really weak nose and so I've not tried but I'm going to atleast give it a go is 20 too old?
