WWE businessman and chairman Vince McMahon has helped to build the wrestling company to what it is today - and apparently, the business wasn't the only thing he was building.

McMahon, now 78, served as the CEO and controlling shareholder of the WWE for 40 years and added a shredded physique while doing so.

The estimated billionaire, who secured a $21million merger with UFC boss Dana White's Endeavour group earlier this year, even works out at 3am.

Besides the ludicrous workouts bizarrely early in the morning, McMahon apparently works out every day - seven times a week.

SmackDown star Big E told the Hollywood Raw podcast: "He has a personal trainer and this poor guy.

"We have these long drives, pre-pandemic, and we'll get in around two or three in the morning and his personal trainer has been standing outside the whole time waiting for him because he'll come in and work out after shows and after long drives.

"This man is in his 70s and he's working out hard.

"He's a meathead in a way."

Sometimes, if he knows he won't be able to work out the next day, the wrestling guru gets in two sessions the day before.

McMahon rotates his gym schedule, switching between chest, arm, leg, shoulder, and back exercises.

Back exercises - by far - are his favorite and strongest part of his body.

Mike Monteforte, McMahon’s trainer and workout partner, said: "On the bent-over row, he can do 315 for 10 reps.

"He has unbelievable strength in his back."

After completing a body part in an exercise, McMahon follows it with a full CrossFit-inspired workout.

The entire workout takes about 90 minutes.

The executive does most of his exercises in giant sets, usually in groups of three.

McMahon even released a sample of one of his back-day workouts.

In the first giant set, McMahon does three sets of lat-pulldowns, followed by the bent-over barbell row and dumbbell shrugs.

After, he completes three sets of seated cable rows, close-grip lat pulldowns, and standing cable pullovers.

Finally, in his third giant set, the WWE legend does three sets of bent-over barbell rows, one-arm lat pulldowns, and one-arm barbell rows.

With his reduced role in the WWE since merging with Endeavour, McMahon will have plenty of time to continue perfecting his body.
