The Olympics can be the perfect place to kick start your career, especially if you are entering in a popular sport like boxing for example.
Many boxers made their names in an Olympic ring, and none more so than English IBF Heavyweight Champion Anthony Joshua.
Back during his amateur days, Joshua was entered into the boxing event at London 2012, and albeit controversially, he came away with gold thanks to a victory over reigning Olympic champion Roberto Cammarelle.

The decision was met with controversy as some boxing experts claimed he only won the gold because of a 'home decision', however, it was only the start for Joshua.
Since then, the 26-year-old has gone from strength to strength in the professional world, winning 17 out of his 17 bouts, with four being in the way of knockouts and the remainders being in the way of total knockouts.
Joshua made his professional debut three years ago in 2013 when he faced Emanuele Leo at the O2 arena. It took him just under three minutes to get the job done in the first round.
However, instead of focusing on Joshua's complete record, we are going to take a look back into his best KO's during his professional career.
Anthony Joshua vs Hector Avila
Joshua's first KO came in his fifth fight back in 2014.
He was fighting Argentinian Hector Avila in Scotland, and he delivered a knockout blow in the first round after just two minutes.
His first KO win, but his fifth during his professional career.
Anthony Joshua vs Matt Legg
Just shy of three months later, Joshua was back in the ring fighting fellow countryman Matt Legg.
This fight didn't even last two minutes, however, as Joshua knocked Legg out in just one minute and 23 seconds in front of a Wembley crowd.
Six fights, six wins.
Anthony Joshua vs Jason Gavern
Joshua had to then wait almost a year for his next knockout victory, despite winning a further four fights in the meantime.
Ahead of facing Jason Gavern, Joshua was 10-0, and that soon became 11-0 when he knocked the American out in the third round, sending the people in attendance at the Metro Radio Arena in Newcastle home happy.
Anthony Joshua vs Charles Martin
Fast forward to earlier this year and you will come across Joshua's most recent victory in way of knockout.
In early April, Joshua fought American Charles Martin, and the Brit ended the bout in the second round in front of a packed O2 arena.
That was his 16th fight, and his 16th win.
It was also a memorable win for Joshua as he won the IBF Heavyweight Title.
So, when watching Rio de Janeiro this summer, keep an eye out on who could become the next Anthony Joshua of their sport. You've got to start somewhere, and the Olympics can be the perfect stepping stone.
