Hated YouTuber-turned boxer Logan Paul looks insane

Pictures show YouTube star Logan Paul’s body transformation is complete ahead of his megafight with boxing legend Floyd Mayweather.

YouTube star Logan Paul looks insane just days out from his megafight with boxing legend Floyd Mayweather.

Pictures from Paul in the gym this week show the 26-year-old looking fierce as he prepares to do what nobody ever has — and stop the undefeated American superstar.

Paul will earn a reported $A26m (£14million) for the fight on Monday (AEST) — and he is doing the work to justify reports it will be one of the highest selling pay-per-view events on the planet this year.

He is stepping up for just his third bout in a boxing ring, the other two coming as a mix of amateur and professional contests with one win and one loss against fellow internet personality KSI.

Now he is stepping up to the big leagues and his new physique matches the magnitude of the rumble.

Logan Paul goes for the jab.

Logan Paul works out at the 5th St. Gym.

Paul has been working out at the 5th St. Gym in Miami and has reportedly been doing the work required to finish a fight of eight 3-minute rounds.

The rules for the exhibition fight were released this week, showing there will be no judges in attendance.

No official winner will be declared, however, knockouts and TKO stoppages are allowed.

The rules also include 12 ounce gloves, no headgear and no judges’ scorecards to decide the contest if it goes the distance.

A knockout either way will go a long way to making people happy.

Floyd Mayweather can catch these hands.

Logan Paul was great as the bad guy in Karate Kid.

Mayweather remains a polarising figure despite his unprecedented 50-0 professional record.

The American’s clash with Paul will not go down on his professional record as it is an exhibition.

In the first press conference for the fight last month, Mayweather and Logan’s brother Jake – who is a 3-0 pro boxer – got involved in a brawl.

Jake grabbed Mayweather’s hat off his head, an act which prompted Mayweather to try and retaliate, but the melee of people managed to break it up.

Mayweather has also refused to rule out the possibility of fighting Jake Paul after the Logan Paul fight — as another monster, easy payday.

The rivalry will be decided in the ring.
