The highly anticipated push-up contest between Dr. Oz and Mark Wahlberg -- all over their breakfast beef -- just went down, and we have a winner ... but it was closer than you think!

After all their trash-talking over whether people should skip breakfast -- the doc thinks you should, Mark says chow down -- they finally met up at an F45 Training gym in L.A. for the showdown.

The gladiators decided on a race to 59 push-ups -- for Dr. Oz's age -- but Wahlberg made it an even 60 ... and won by a few seconds. Pretty close, but take a look -- seems like the buff movie star was toying with the doctor a bit. Looks like Mark edged him out in form too, but keep in mind he IS 11 years younger. If ya need a reminder, check out the abs!

Afterward, Dr. Oz was feeling pretty good about his performance, and even thinks he might have gotten the better of Mark. Debatable, but he also tells us Wahlberg is trying out intermittent fasting and has come to the #cancelbreakfast table.

So, long story short ... the fitness challenge itself went to Mark, but Oz may win in the long run if Mark changes his daily diet. One thing's clear -- both of these guys really care about staying fit and healthy ... after the challenge they ran through an F45 workout.

Britney Spears is giving pop music a whole new meaning ... it's the very loud sound her foot makes after breaking it following this electric dance routine.

You'll recall Britney's boyfriend, Sam Asghari, revealed last week Britney broke her metatarsal bone on her left foot that required a trip to the hospital. Well, fast-forward to Wednesday and Britney posted a video of the dance routine that broke her foot.

You won't see anything crazy but it's the loud pop you hear that'll make ya wanna schedule a foot rub. Britney captioned her video saying, "I haven't danced in six months so I was full throttle at this spot. And yes .... I know I'm barefoot .... don't laugh but I grip the floor better that way!!!! PS you can hear where I broke my foot here. Sorry it's kind of loud!!!!"

Some of the biggest stars are spending their downtime getting pumped up and are happy to show off what they've been working out -- and when it comes to social media ... these jacked stars are bringing out the big guns!

Antonio Brown's got lightning-fast reflexes ... but even that wasn't enough to keep him from getting hit in the head by an errant piece of gym equipment.

The out-of-work NFL star appeared to be working out at his 84/7 training facility in Florida -- pushing big weight on the bench press -- when another piece of gym equipment got loose and crashed down on his head.

It's unclear why the workout machine got loose -- but don't worry, AB didn't appear to be injured.

Just a reminder ... be careful in the gym!!

As for his career, Brown has been training like a maniac and recently told TMZ Sports he plans on meeting with team reps at the NFL Combine in Indianapolis when that event kicks off this weekend.

Of course, Brown has a LOT going on off the field that could prevent teams from pulling the trigger -- including an ongoing battery case, allegations of sexual assault, baby mama issues and a very nasty beef with the Hollywood Police Dept.

We know he can play ... but will a team look past everything else to get him on the field?

Jonah Hill has mad skills in the water, which is incredible ... considering it was a great fear of his until just last year.

Jonah hit the sand with his surfboard just before 10 AM Friday in Malibu.

Pretty impressive ... considering the waves off PCH can be pretty intense.

He joined around 20 people who were catching waves as they enjoyed the sunny SoCal weather. Sorry Chicago, sorry New York, sorry New Hampshire, sorry Vermont, sorry South Dakota ... and especially sorry North Dakota.

After surfing for an hour, Jonah mugged with some of his fellow surfers before braving Pacific Coast Highway for the ride home.

Back in August, when Jonah started surfing, he said, "Been terrified to surf my whole life. Totally random fear and at the same time always been a secret dream of mine."

Timbaland's body is damn near unrecognizable from where he was a couple years ago -- and he's crediting his will power ... for keeping him in the gym, and off prescription pills.

Justin Timberlake's fave mega-producer was on "TMZ Live" Friday, rocking a muscle tee, no less, and showing off his brand new physique. Seriously ... the guy's looking ripped after losing more than 130 pounds.

Tim told us he knew he had to "hit the reset button" when he kept having dreams about how his body should look. He'd also gotten a pre-diabetes diagnosis from doctors ... not to mention his addiction to Oxycontin and Percocet.

He got hooked when the pills were prescribed following a root canal. After his experience, Tim says doctors gotta find a better way to help patients cope with pain.

As for his weight loss goals? Tim says he's still pushing for another 30 to 40 pounds. As he put it, "I wanna be a better me."

Just watch ... it's a great dose of weekend motivation!

Dwight Gooden's got a real-deal boxing match coming up, and he clearly ain't taking his opponent lightly ... 'cause the MLB legend hit up the UFC Performance Institute in Vegas for a hardcore training sesh.

The 55-year-old NY Mets legend is facing 29-year-old "Nitro Comedy Tour" star Catfish Cooley -- who's gone viral on YouTube for his redneck comedy -- on March 7 at the Showboat Casino in Atlantic City.

Gooden -- a 4x All-Star and 3x World Series Champ -- recently hit up the PI ... and worked on his striking with his coaches.

This will be Doc's first fight ... but not the first time he's been inside the squared circle.

Back in 2019, Doc reffed a celeb fight that featured Dustin Diamond ... aka Screech from "Saved By The Bell."

As for the tale of the tape, Catfish squats over 600 pounds and is 36 years younger than Doc ... but he's also 10 inches shorter, and not an all-time legendary athlete.

These guys try to kill each other in just over 3 weeks.

Liam Hemsworth's going with a sleeveless look these days ... but it might be because he can't find shirts big enough for his massive guns.

Seriously, the youngest Hemsworth bro is giving Thor a run for his money in terms of bulging shoulders, biceps and forearms ... and The Hulk for that matter.

Liam could barely straighten his arms as he was seen leaving the gym in Beverly Hills, but he looks pretty pleased with his jacked status. Of course, we're told he was heading to meet up with his new reported girlfriend, Australian model Gabriella Brooks, for lunch ... so that probably put some extra pep in his step.

It's nothing new for Liam to be in peak physical shape, but his muscular transformation in just a few short weeks since he was spotted on the beach in Byron Bay is pretty incredible.

Check this out, James Harrison ... there's a defensive lineman who's throwing around a ridiculous amount of weight in the gym ... and it's super impressive.

Myles Garrett did his best impression of the former Steelers superstar Thursday ... posting a video of himself deadlifting what appears to be about 465 pounds with a trap bar -- multiple times!!!

Oh ... and for some of the reps, he's wearing a big-ass weighted vest loaded with 100 pounds.

Now, Garrett lifting heavy weights ain't exactly breaking news ... the dude threw up 225 pounds 33 times at the NFL Combine in 2017.

FYI -- only 2 other guys in the entire draft completed more reps.

Back in January, the Browns star also posted video of himself benching 425 pounds.

MG's still indefinitely suspended for swinging a helmet at Mason Rudolph's head ... so seeing him get after it hard in the gym is a sight for sore eyed Cleveland Browns fans who want Myles back on the field.

Garrett looks shredded -- and is obviously crazy strong -- but he's still got work to do if he wants to match feats of strength with the dude who once benched 500 pounds and pushed around an 1,800-pound sled.

Jon Jones says he's radically changed his diet for his upcoming fight with Dominick Reyes -- telling TMZ Sports, "About 80% of my meals have gone plant based now."

The UFC superstar has been a big fan of meat in the past -- he even promoted the ButcherBox meat company on his Instagram in 2019.

But Jones tells us he's switching things up for his UFC 247 fight against Reyes -- and decided to cut a bunch of animal protein out of his diet this time around.

"I switched up my diet a little bit, I started eating plant based," Jones says.

"Cardio feels great, I’m lighter than I normally am. Normally I weigh at least 222 around this time. Right now I’m already 215. So I’m ahead of schedule majorly in my weight cut, which just allows me to focus on happiness and relaxation, and I just feel perfect."

Jones says he's laser-focused and ready to fight on Feb. 8 -- and is gunning for a highlight reel-style knockout -- but as long as he gets the "W," that's all that matters.

"It’d be nice to make WorldStarHipHop for some awesome KO, or make TMZ for some awesome KO. But that’s not really my style."

"I feel like when you go out there and you tell people, ‘I’m gonna knock this guy out right away’ and then you find yourself going into the 4th round and you still haven’t gotten that KO. You start panicking in your head a little bit when your plan is going wrong."

Bob Harper says what makes the 'Biggest Loser' reboot a big winner is what happens AFTER the contestants go home ... when the real work begins.

The host of the new 'BL' was on "TMZ Live" Tuesday, and while they're still going to have weight loss competitions ... he says the contestants will also be getting a huge helping hand whenever their time on the show ends.

The fitness guru also emphasizes the reboot's done away with "temptation challenges" and vote-offs. Bob explained there's a concerted effort to give contestants the necessary tools to continue a healthy lifestyle at home and on their own.

Arguably, that's the toughest part for most of the 'BL' cast ... according to Bob. The show's now airing Tuesday nights on USA and, overall, he says you can expect a "kinder, gentler" approach to slimming down.

Aldon Smith has cleaned himself up and is laser-focused on getting back in the NFL, so says Jay Glazer who tells TMZ Sports ... the former All-Pro deserves a 2nd chance.

The 30-year-old defensive end was a MONSTER in the league before substance abuse issues and domestic violence allegations derailed his career.

But, Glazer says Smith had an epiphany -- and made a life choice to turn his life around, starting with joining Jay's Unbreakable gym in West Hollywood.

"Aldon's great because Aldon's been working out with our [military veterans] in our MVP program every single Wednesday night," Jay said.

"Aldon has been sober for a while and he's been helping a lot of our vets with their sobriety."

Smith - who hasn't played a down in the NFL since 2015 -- is now trying to show NFL teams he deserves another shot in the league ... and Glazer believes he's earning it.

"We've given a lot of guys second chances. He deserves it as much as anybody I've been around," Jay told us at his GlazerPalooza event at Prestige Imports Miami, where a bunch of SICK exotic cars were on display!

The event benefits Jay's MVP charity which helps military vets and athletes who are dealing with mental health issues.

Jay says Aldon -- who set the 49ers franchise single-season sack record in 2012 (19.5 sacks) -- is currently at a solid 285 lbs and SHREDDED.

"He is a freak if nature."

Actor Kumail Nanjiani didn't have to make a New Year's resolution, because he's stayed jacked!!!

Kumail was hangin' with a friend Friday at a restaurant in the Los Feliz area of L.A., and it's pretty clear from the pose -- he hasn't lost an inch of mass or muscle.

The 41-year-old stunned everyone with his chiseled pic ... displaying his washboard abs and super vascular arms. He got ripped for his new flick, "Eternals" ... which is set for release in November.

As you know ... Kumail is best known as a nerdy computer geek on "Silicon Valley," which ended last year. During the last season, the nerd's arms were bulging out of his shirt. His career hit a new level in 2017 with his movie, "The Big Sick" -- a true story about his wife.

Hollywood relationships can get weak ... but these hot couples -- with some extra encouragement from their partners -- are making sure they always put the work in to stay strong!

From famous faces such as Chris Hemsworth and Elsa Pataky, Jennifer Lopez and Alex Rodriguez, Adam Levine and Behati Prinsloo, to Kelly Ripa and Mark Consuelos it seems like the hard work has been paying off!

These hot couples are on top of their game ... Dive into our gallery of celebrity workout couples to see all the hot pairs making sure they are at their lookin' good together!

Troubled NFL star Aldon Smith isn't giving up his dream of getting back on the football field ... 'cause he's training like crazy in hopes of making a return to the league.

30-year-old Smith hasn't played a down in the NFL since 2015 due to a variety of issues including substance abuse, a hit-and-run and domestic violence allegations.

Before the off-the-field issues, Smith was one of the most dominant players in the league -- he was a 1st Team All-Pro in 2012 when he recorded 19.5 sacks ... setting the San Francisco 49ers single-season franchise record.

Young Thug knows how to motivate the guys in his crew -- offer up a fat stack of cash ... and watch 'em go!

The "Hot" rapper was clowning around with his boys Thursday evening outside the Sunset Marquis in West Hollywood when things turned into a fitness challenge ... as they often do.

Thug bet one of his pals he couldn't run up and down the street -- which is on a fairly steep hill -- and pulled out his money to show him what was at stake.

The guy accepted the challenge, and despite getting roasted for his running form -- or lack thereof -- Young Thug ponied up the dough. However, he made sure to rub it in by running the hill himself ... without all the huffing and puffing.

What makes Thug's running even funnier is the fact he's rocking super-skinny jeans

BTW, he's got a show Friday night at Avenue LA. No word if he's jogging to it.
