JACOB Soboroff has shared a glimpse of his intense routine away from his hosting duties.
The Today star has been busy filling in for permanent host Carson Daly, 50, amid his unexplained absence.

In an Instagram Story last week, Jacob, 40, showed off his fit physique as he prepped for a half marathon.
The shot showed the Los Angeles-born journalist on a damp road, with his hair looking pristine despite the wet conditions.
Jacob went without his usual glasses, and showed off his toned body as he snapped a selfie mid-run.
In his caption, he added green ticks on a list next to the items: "14 weeks of training; five runs a week; two continents; four (or more?) US states; one last shakeout run just now."

He ended his list with a nervous emoji, next to the item: "One half marathon tomorrow."
In a new social media update, however, Jacob revealed that he had no need to be nervous about the race.
In the post, the star was filmed as he crossed the finish line alongside his friend Barnett A. Zitron.
The duo was captured by their families as they ran to the end together, stopping to wave as their supporters screamed in encouragement.

Jacob captioned the post: "@barntron and I ran solo half marathons across the country the same day during COVID.
Today we did one together in Brooklyn and he waited for me to cross the finish as you can see here.
He added: "Thanks @nicolecari for the video and to you and @lindsaytodres and @alizitron for being at the finish line with the kids and screaming like maniacs," along with a crying emoji.
'EVERYTHING'S FINE'
Although Carson has been frequently absent from Today over the summer, he seemed to be balancing his duties with his hosting role on The Voice.
Late last month, he took to Instagram to share a photo of himself fake crying behind the scenes of the competition show.
"My first day ever shooting @nbcthevoice without @blakeshelton," Carson captioned his photo.
"We had a ritual of getting hair & makeup together for 23 seasons. I think I’m handling it well. Everything’s fine."
Blake Shelton departed the show after its last season, with the duo separated as Carson continues on with his hosting work.
BETTER THAN EVER
Earlier this summer, Carson opened up about his life, career, and mental health struggles.
In an interview celebrating his 50th birthday, Carson said he feels better today than he did in his 20s - mostly thanks to improvements in his mental health.
Carson revealed that he struggled with undiagnosed generalized anxiety disorder when he began his broadcasting career at 23.
"I suffered for so long without knowing what it was," he said.
"I was scared a lot. I always felt panicky. You know that feeling of losing your phone or your wallet? That's how I felt all the time."
The constant stress was taking a toll on Carson's day to day activities.
"I couldn't relax," he said. "I couldn’t enjoy life."
The Today host explained that once he was diagnosed he was able to better manage his stress with cognitive behavioral therapy.

"I now have the tools to work through my anxiety," he explained.
"I’ve never felt this strong mentally, and that’s one of the reasons I feel so good about going into my 50s."
