Dynamo: I had half my stomach removed and had to learn to walk again
But, until now, Dynamo - real name Steven Frayne - has never spoken about the life-or-death health struggle that led him to pursue his magic dream.
The 29-year-old - nicknamed Magician Impossible - was diagnosed with Crohn's disease as a teenager, leaving him facing an impossible choice: months of debilitating dialysis or a life-threatening operation.
His brave decision changed the course of his life and would end up making magic cool again.
'All the kids at school had gone through puberty and were 10 times bigger than me,' Dynamo tells Now's Dan Wootton.
'I had loads of tests over the course of a year and eventually I was diagnosed with Crohn's disease.
'My body has to fight it every day. It's physically painful to digest food.
'It's a bit like having an open wound inside your tummy.
'Every time you eat it's like rubbing dirt into that wound. It never heals.
'It was so uncomfortable when I was going out on dates and I had to spend 30 minutes in the toilet.
'I was on 25 tablets a day and partly because of that I developed an abscess in my stomach when I was 19.
'That put me in hospital for four months for more tests.
'The doctors came to me with two options.
'I could stay in hospital on dialysis for another six months and be too weak to do anything.
'Or I could have an op to remove half of my stomach, which was a new procedure and had never been done on anyone as young as me before.
'It was life-threatening and I was told that if it didn't work I would die.
'They took out part of my small bowel that was inflamed, then stitched it back up.'
When Dynamo woke up he couldn't feel his legs because they'd cut through nerves in my tummy.
'I'd basically ended up disabled,' he recalls.
'I had to learn to walk again.
'I had no strength or control - I couldn't even pick my legs up.
'I was another six months in hospital.
'I wanted to be going out to clubs and meeting people.
'Then afterwards I was embarrassed by my scar.
'It took me a long time to realise that girls like scars - the S-shape of mine even makes the definition of my abs better!'
Dynamo's autobiography Nothing is Impossible (£16.99, Ebury Press) is out now.
