James Corden joined Mark Wahlberg's morning workout on 'Late Late Show'

From "The Late Late Show" to early early workout!

On Wednesday's "Late Late Show," host James Corden joined Mark Wahlberg for one of the actor's infamous pre-dawn workouts.

Perhaps the only thing that got your bone funny.

Wahlberg went viral in September when he shared his daily schedule, which includes waking up at 2:30 in the morning and then working out from 3: 40-5: 15 am, an activity that has been dubbed "The 4 am Club" for those who take part.

Corden, 40, woke up at 2:25 a.m. and, as you might imagine, was not exactly looking forward to breaking a sweat with Wahlberg. Wahlberg's time to pray, Corden quipped, "I'm praying that he cancels."

A bright-eyed and bushy-tailed Wahlberg, 47, greeted Corden at his home gym. Corden marveled at how early it was. "Is not it nice and peaceful, though, when do you get up (early)?" Wahlberg replied.

"I was more peaceful when I was flat-out asleep," Corden said. "I was completely peaceful."

The duo then did some light stretching to get ready, during which time Corden mused, "I do not even know if I'm still awake or if this is some sort of weird dream."

Wahlberg Ella, 15, and Grace, 8.

"When the girls get older the boys coming over, ringing the bell. You gotta be ready! "The" Instant Family "star said. "There's a whole other fight in front of you."

Corden did not flinch, firing back with, "I'll just say I know Mark Wahlberg. Do not mess with me because I'll call him, he'll come over, provided it's before 5 p.m. Otherwise, he'll be asleep. "

Wahlberg then put on a rope with an intense workout that was exhausting just to watch.

While doing some lunges, Corden hit his stride, declaring, "Now I feel like we're in a boy band and I'm enjoying it" before he broke out into "Everybody Backstreet's Back" by Backstreet Boys.

Corden also presented Wahlberg with T-shirts with their pictures on their heels made commemorating their time at the "Club." Corden pretended to be mystified after Wahlberg noted, "You look a little more like me."

When Wahlberg said that they had just finished the warmup, Corden said, "I'm out" and joked he'll return the next day at midnight to "get a couple of hours in before you wake up."

After Corden left, Wahlberg said, "Just make sure he does not throw up in my bathroom."

While the daily schedule is becoming legendary, Wahlberg does dispute some of it. During a recent interview with Willie Geist on Sunday TODAY, he shot down the notion that he spends 90 minutes cleaning himself. "There's no hour-and-a-half shower," he said. "I probably took a five- to seven-minute shower."
