Joshua burst onto the boxing scene in 2012 when he claimed a gold medal at the London Olympics.
He had been fighting as an amateur for five years and turned pro one year later with a record of 40-3-0.
After 30 months as a professional, knocking out each of his 15 opponents, ‘AJ’ claimed his first world title in a two-round demolition of Charles Martin.
Joshua’s stoppage streak ran until this March, when he boxed smartly against undefeated WBO champion Joshua Parker to claim a points victory.
The WBA, WBO and IBF heavyweight champion defends his belts against Alexander Povetkin at Wembley this Saturday.
Ahead of that fight, the 28-year-old conceded that he does have regrets about his early career choices.
“I should have gone to the 2016 Olympics and then I should’ve just turned pro now, or be two years into my pro career,” Joshua told Sky Sports Boxing.
“I would’ve been a lot more seasoned – fast forward and imagine six years from then as a pro, I would’ve been a lot more seasoned.
“But I’m starting to get my season now in the gym. I’m learning how to slip shots, spin off.”
The Watford fighter turned down £50,000 to turn pro in 2010, but instead penned his signature with Eddie Hearn’s Matchroom Sport.
Hearn plotted a steady rise in Joshua’s embryonic pro career, which helped Joshua in his gradual development of the sweet science.
“I didn’t have a long amateur career, but I did have heart and determination which got me through,” Joshua added.
“I was always looking at it fight by fight, not knowing where I would end up, but knowing that I always had determination and that discipline.
“But early on, all these KOs and wins have just come on auto-pilot mode. They were just strength and determination.”
