The 4'4' dwarf, who resides in Florida, has lifted as much as 36 stone.
With women, he is no less ambitious.
Kraft , 52, only dates women who are more than a foot taller than he is. For the past six months he has been dating 6'3' China Bell.
Bell,
43, who was born male and has since transitioned, admits she was unsure
when he first asked her out but was quickly bowled over by his
weightlifting skills.
'I think
Anton's weightlifting is so sexy because I think he's sexy - when you
hold a world heavyweight title, that means a lot,' Bell said.
'I've never dated a 4'4" guy and I was just so curious. I'm glad I gave him a chance because he's an amazing person.
'I'm different and he's different, and where we're from, different is good.'
In 10 years of power lifting, Kraft claims to have the highest bench press record of all time for his weight class.
But it seems he may have pushed his body too far.
He says he has 'technically died' five times before being resuscitated - ranging from drowning to falling out of a window.
Doctors also fear he may have a heart attack if he keeps up his all-action lifestyle.
Kraft is undeterred.
'Some
people say that what I do is weakness, or micro-man syndrome - that I
want to do something that I am not built for, to prove something,' he
said.
'But I believe there's only one winner - second is first loser. Second doesn't count.
'Overall, I am one of the five strongest guys in the world, regardless of height and weight.
'And I am the only guy in the world who has ever benched four-times his body weight.'
His driving force, he says, is his girlfriend.
'We used to walk against the current, but the current has changed,' he says.
'Florida is one the states that have same-sex marriage - and both of us are basically the same sex.
'I enjoy dating a transgender woman because she was born a male and is doing the utmost to become as feminine as possible.
'I find that most women born as women do not spend as much time on their appearance.
'Right
now I feel like I'm the luckiest man on the planet - we are all happy
and good and I have never felt better than I do now - and that would be
thanks to China.'
