Who's got the balls to talk trash to LeBron James???? (besides Charles Barkley) ... how about the GREATEST competitor in the history of "The Challenge!!!"

TMZ Sports spoke with 'Challenge' legend Johnny Bananas ... who's DOMINATED on the MTV show for years ... and he strongly believes LeBron wouldn't stand a chance in his world.

FYI, "The Challenge" is a bunch of hot dudes and chicks who party their faces off and sometimes bang each other at night ... and then go to war in grueling physical competitions during the day. New season premieres tonight.

It's crazy ... these people are legit athletes.

So, we asked Johnny how a world-class physical specimen like LeBron would hold up. He ain't too confident in the King.

Beware, NBA forwards ... you might have a 6'9", 300 lb problem ... 'cause TMZ Sports has video of Glen "Big Baby" Davis putting in some serious work in hopes of making an NBA comeback.

Davis hasn't been in the league since the 2014-15 season ... but he wants back in -- and we've got footage of the guy busting his ass at the Sports Academy in Thousand Oaks, CA.

We're told Davis has been training at the S.A. 5-6 days a week -- working with a full team of specialists focusing on strength and endurance. He's also got a nutritionist and a "mindset development guru."

How do you like your Jason Momoa ... blonde or brunette??

Now you have choices, thanks to NFL stud defensive end Bryan Braman -- who says he gets mistaken for the jacked up actor EVERY DAY!

Braman -- who's about to be a free agent -- says he loves the comparison and says he's even down to be Momoa's official stuntman ... 'cause he's down to do all the dangerous stuff.

But who's got the better abs? Braman states his case.

He also gives us a man bun tutorial on the street -- and one thing's clear ... dude's got BEAUTIFUL HAIR!!!

The new Mr. Clean can't rest now that he's scored the iconic role -- instead he's got serious work to do in the gym.

We got Mike Jackson in Houston where his new employer's hooking him up with 2 Super Bowl tix. As they say, nothing's free though because Mike strongly hints he's been told to pump things up. He looks pretty big in this video, but insists he can't match the OG Mr. Clean just yet.

As for the best music to clean to -- Mike's fave is a classic, but he's saving his dance moves for Super Bowl Sunday.

For the record ... we think he's off on the size thing.

Senator John Thune revealed to our photog ... the only place on Capitol Hill where Democrats and Republicans can put aside their differences is in the Senate weight room.

We got the South Dakota Republican at Reagan National Airport Monday and he vouched for NY Senator Chuck Schumer, saying his tears were real because he's an emotional guy, even at the gym.

That opened the door to talking about the super exclusive Senate gym, and who knew this is where political enemies lay down their differences.

And if you believe him, the weights are mislabeled ... because in D.C. it's all about power!!!

The U.S. Air Force wants to join the indoor cycling craze ... and they're looking for a super good spinner to lead the cardio charge.

According to docs obtained by TMZ ... the Air Force is revamping its Fitness and Sports Program. The brass wants to hire instructors for spin classes at Patrick Air Force Base in Florida.

The Base will hire a contractor to provide the backdrop for a good spin session, and they'll then install the necessary equipment, including a sound system.

Classes will be held on Tuesday and Thursday -- 2 a day throughout 2017. They will range in length from 45-60 minutes.

According to the specs, instructors must supply their own batteries for their headsets.

Lily Collins will take a Friday 6-pack to go from the gym -- but we all get to enjoy.

Phil's daughter left the gym in Bev Hills and looked like she got in a major workout.

Joe Jonas is flaunting his body of work ... 16 weeks of intense work to be exact.

The DNCE frontman bulked up and then shredded by weight training and boxing at Unbreakable Gym in West Hollywood. The gym's co-founder (and 'NFL On FOX' star) Jay Glazer says Joe committed to a pro-athlete training regimen that included specific caloric intake and two-a-day workouts.

Can't argue with Joe's results, but here's the thing -- his little bro, Nick, pumps up at the same gym, and recently showed off a bulkier physique.

So, we gotta ask ...

Conor McGregor hooked up with badass gold medal winning wrestler Helen Maroulis in Ireland ... and spent hours training with the Olympian.

Maroulis -- the first American female wrestler to take gold in the Olympics -- posted a picture with Conor on Instagram ... leading people to wonder why the wrestler and fighter were together.

Helen gave us the answer ... it was all about working up a lather!

"It was awesome. We rolled around for a good while. Play wrestling, sparring," Maroulis told TMZ Sports. "He kinda showed me the differences when you're wrestling against the cage which is obviously very different than regular wrestling."

Helen says the lessons from Conor didn't end on the mats ... he also schooled her on handling the media.

As for when we'll see her fight, Helen insists she still hasn't made up her mind on the move to MMA ... but all signs seems to be pointing to a foray into the combat sport.

Prince Harry doesn't want kids in the UK to go without a roof over their heads ... so he's popping a squat and breaking a sweat to make sure that happens.

Harry went into full workout mode Thursday with members of The Running Charity in London -- an org that raises money and helps homeless youths find housing and stability.

He's clearly serious about the cause ... as seen in his impeccable form. Well done.

Trick shots. Thunderous dunks. Crazy feats of athleticism.

The insanely athletic spawn of Metta World Peace and Shaquille O'Neal BALLED OUT HARD during a high school showdown in L.A. ... complete with some VERY impressive highlights.

Shareef O'Neal's Crossroads High School traveled to Ron Artest III's Bev Hills High Tuesday night -- where the prep stars battled it out in a game that literally came down to the buzzer.

In the end, Artest's team came out on top 50-47 ... but you gotta watch these highlights -- we're guessing they'll see each other again in college.

4:05 PM PT -- Q did die from a heart attack, according to the San Diego County Coroner. Autopsy results also list "obesity" as a contributing condition. He failed to respond to CPR, and was pronounced dead on the scene.

WorldStarHipHop founder Lee O'Denat -- better known as "Q" -- had been on a fierce path to slim down in the weeks leading up to his death.

We're told Q, the face of WorldStar, had been going HAM in the gym and on the treadmill -- sometimes at 5 AM. People close to him say he was over 300 lbs. at his heaviest, but had been trying to shed weight to look his best for his new MTV reality show ... slated to premiere in the Spring.

The show revolved around 43-year-old Q, his website's crazy videos and celebrity guest appearances. We're told Q had been telling friends how insanely busy he'd been juggling the show and his new gym life.

TMZ broke the story, Q died in his sleep Monday night. An autopsy is set for Tuesday.

President Trump just imposed a hiring freeze on the federal government, which makes what we found all the more surprising ... the Department of Homeland Security is shopping for gyms.

DHS filed legal docs, obtained by TMZ, in which they solicit bids for a "full-range health & fitness center" for employees who work in Immigration and Customs Enforcement (ICE).

ICE is on the hunt for a gym with "state-of-the-art fitness equipment" within walking distance from one of its D.C. offices -- a quarter mile on the outside. The agency is currently taking bids from local vendors.

The document -- dated January 13, 2017 -- states ICE will foot the bill for its employees for 12 months, starting in March, with an option to extend the contract an additional 3 years.

The document sets a limit of $200,000 for the annual memberships.

Kim Zolciak is coming to daughter Brielle Biermann's defense denying the 19-year-old has ever had butt implants, despite what the Internet thinks.

Brielle posted a racy pic of her rump on Snapchat and many jumped to the conclusion that it was fake since she has posted video of her lip injections in the past.

However, Kim tells TMZ the proof Brielle's got natural cakes is in the rest of her body ... there isn't an ounce of fat to use for butt implants. Kim says Brielle's big ass comes from the gym -- she works out a ton.

Not to mention ... she's 19.

This kid is absolutely ridiculous.

LeBron James Jr. -- 12 years old -- has a brand new highlight reel ... and we guarantee it'll make you say, "DAMN" at least 3 times.

In the new footage, Bronny puts on a clinic -- passing, handles, defense and ridiculous step-back jumpers.

He even pulled off the water bottle challenge at the end.

Bronny's dad has already said the kid's being recruited by major colleges ... he's still got 6 years to decide!

Enjoy the clip.

Mike Pence has great resolve on one thing once he becomes Veep ... exercise.

We got Pence on Capitol Hill Tuesday and it seems he's not putting the bike he regularly rides into storage.

It creates an interesting problem for the Secret Service if Pence ventures out into the open. President Clinton famously jogged around the Lincoln Memorial and the Potomac ... a big security challenge.

We're guessing the subject of stationary bikes will come up soon.
