UFC

We've all seen athletes do regular push ups. And clapping push ups. And diamond push-ups ... but have you ever seen anyone do BACKFLIP PUSH-UPS?!

Meet UFC fighter Chad Mendes ... who showed off his acrobatic workout skills at a media event for his upcoming fight against Nik Lentz at "UFC on Fox 9" in December.

For good measure, Chad also knocks out a "clapping behind the back" push-up.

Last time we saw anyone pull off push-ups like these ... was right before we turned off "Don't Mess with the Zohan."

Jon Jones is no match for Wladimir Klitschko or his brother Vitali -- so claims Joe Rogan ... who tells us the UFC champ's goal to beat one of the Ukrainians is laughable.

Joe couldn't have been clearer before blowing out of  LAX ... Jones wouldn't stand a chance in the boxing ring with either Klitschko -- both world heavyweight boxing champs.

Rogan says Bones WOULD have a better chance in an MMA fight ... but one Klitschko would still have a serious edge.

UFC Hall of Famer Chuck Liddell fought an intense battle in L.A. this week -- no octagon ... just octonauts.

The Iceman waded through hoards of children at the Topanga Mall -- daughter in tow -- to check out "Octonauts! Live" ... a stage production based on the popular Disney show.

The kiddie crush was all smiles as they gazed at Captain Barnacle and Kwazii -- but by the look on Chuck's face, he just took one for the team.

Watch the show open and listen to the theme song ... you'll understand.

Jon Jones may have had his face bashed in at UFC 165 last night -- but that didn't stop the light-heavyweight champ from flashing his extremely swollen face for a photo after the fight.

Jones' opponent Alexander Gustafsson posted the gnarly pic this morning online -- showing a beat up moment of respect between the two fighters inside a Toronto hospital after the pay per view.

UFC badass Miesha Tate says she won't rest until she BREAKS Ronda Rousey's face ... telling TMZ she doesn't just wanna win when they fight -- she wants to knock Ronda's ass out cold.

Tate -- who's currently a coach on Fox Sports 1's "The Ultimate Fighter 18" -- was out in NYC yesterday when she told us how she plans to defeat Rousey when they face off at UFC 168 in December.

"I'm just going to smash her," Tate told us ... "I want her to wake up and see the ceiling and the headlights and me standing over here with the belt on already."

It ain't gonna be easy ... Rousey's undefeated in the world of MMA ... and she's pretty handy with the arm bar.

Still, Tate's confident -- telling us, "I would love nothing more than to break her jaw."

Here's some video of Tate in action -- she's a BEAST!!!

Soooo ... Joe Rogan works out.

The UFC announcer went shirt-off at the beach in Hawaii this weekend ... proving Carrot Top ain't the only comic who knows his way around the weight room.

Fun Fact -- Rogan also happens to be a black belt in Brazilian jiu-jitsu ... which is why we're immediately issuing the following apology for comparing him to Carrot Top.

Sorry Joe.

MMA legend Tito Ortiz is no stranger to bad breakups ... and tells TMZ he's moved on from the UFC because he knows Dana White ain't lookin' to bury the hatchet anytime soon.

Dana and Tito famously trashed each other following Tito's last UFC fight back in 2012 ... and Ortiz has since struck a deal with Bellator, a rival MMA organization.

In fact, Ortiz is set to fight fellow UFC-defector Rampage Jackson under the Bellator banner in November.

But, when we asked Tito if there was any chance at patching things up with his former boss and returning to the UFC ... Tito simply explained, "Nah, Dana holds grudges."

It ain't the first time Tito and Dana have gone after each other -- they also tore each other apart back in 2008 ... and Tito left the UFC ... only to return one year later.

Tito Ortiz is scrambling to protect his reputation in the face of a public smear campaign ... helmed by his baby mama Jenna Jameson -- telling TMZ, whatever she's about to say on TV is bound to be filled with lies ... because she's a dirty liar.

FYI, Jenna recently sat for an interview with "Entertainment Tonight." It's unclear what the interview is about, but Tito's guessing he's a main talking point ... and given their sordid history, he probably isn't portrayed in the best light.

So he's coming out to clear his name preemptively -- telling us, "I want to make it very clear that any and all allegations she has made about our personal life and my character are completely false. Jenna continues to paint a picture of distorted reality, which has been hurtful to both myself and my family. I hold sole custody over our boys, which speaks for itself."

He adds, "I am moving on with our life and with our boys, and I pray this is all over soon. I wish Jenna would get help to not only save herself, but for the children she brought into this world."

He was a joke in "Street Fighter" ... he sucked in "Double Team" ... but Jean-Claude Van Damme could BEAT YOUR ASS in real life, so says UFC champ Georges St-Pierre.

A well-dressed GSP was out being a badass in NYC yesterday when we asked if he thought martial arts legend Bruce Lee would be able to dominate in today's UFC (c'mon, of course he would).

But Georges said the superfight he'd REALLY like to see is Van Damme vs. Chuck Norris -- "I think that would have been the best showdown."

GSP says he's trained with JC in the past and says the Muscles from Brussels is no joke when it comes to fighting (see: final scene from "Bloodsport").

Of course, Chuck Norris is kind of a badass too -- he once FOUGHT A BEAR!

Two years after UFC badass Brock Lesnar was forced to retire due to serious stomach issues, the Beast Incarnate proved his guts are still TOUGH AS HELL ... by woofing down enough food to feed a small Italian village.

As you may recall, Brock was diagnosed with a severe case of diverticulitis back in 2009 -- a digestive tract disease that usually forms in the large intestine -- and after multiple surgeries, he was forced to retire in 2011.

But things are lookin' up ... 'cause TMZ has learned Lesnar and his wife Sable hit up Fresco restaurant in Montclair, NJ on Monday ... and Brock put his belly to the test.

Check out what he ate:

-- Ahi tuna with asparagus (shared)
-- Margherita pizza (shared)
-- Chicken Parm ... with TRIPLE-EXTRA chicken
-- Full bowl of parpadelle bolognese

... and, to top things off, dude crushed a slice of cheesecake by himself.

We're told the entire meal cost just north of $500 ... PLUS, we're told the WWE star left a "very generous" tip to everyone who stayed past closing time to take care of him.

Awesome.

Newly-crowned UFC champ Chris Weidman says he's unstoppable -- telling TMZ, he destroyed UFC's reigning middleweight king Anderson Silva when no one else could ... and he's ready to do it again in a few months.

There's a lot of speculation that Silva succumbed to Weidman over the weekend because he's getting old and has lost his edge -- but Weidman's not buying it, telling us Silva was as strong as ever in the Octagon ... he just wasn't strong enough.

Sounds like fighting words to us ... which is good because Weidman and Silva are already set to rematch very soon.

Screw Disneyland ... after Chris Weidman delivered his KO punch to Anderson Silva, the new UFC champ took his fists straight to a Vegas club to reap the spoils of his victory.

The celebration went down at Surrender Nightclub inside the Wynn hotel. We're told Chris rolled in at 1:30 AM with a crew of about 40 people ... including NBA champs Mike Miller and Udonis Haslem.

He also brought his giant championship belt.

Some people said it couldnt be done ... but last night reigning UFC champ Anderson Silva LOST his first title fight in seven years ... when Chris Weidman knocked his ass out.

It all went down in Las Vegas as the MGM Grand Garden Arena. Chris and Silva faced off ... with Silva -- considered the best MMA fighter in the history of the sport -- defending his seven-year stronghold on the middleweight title.

But Silva was fighting cocky -- with his hands down -- and by the 2nd round it caught up to him ... when Weidman caught the Brazilian with a nasty left hook. Silva instantly went down and Weidman was crowned the new champ.

Ex-UFC champ Ricco Rodriguez has just dodged the strong arm of the law in his drunk driving arrest ... TMZ has learned.

The "Celebrity Rehab" Season 1 alum was arrested in March on suspicion of DUI.

Rico copped a deal, and pled no contest to "wet reckless" -- reckless driving involving alcohol. It's not as serious as DUI, but gets the point across. The DUI charges were dropped.

The former champ won't spend any time in the pokey, but he will be on probation for 3 years. And he was socked with the obligatory $300 fine and a 12-hour alcohol ed program.

Marcellus Wiley thinks 51-year-old Herschel Walker is CRAZY for thinking he can make an MMA comeback ... because as the old saying goes, "Father Time is undefeated."

Our photog spotted the former NFL star (and current ESPN Radio host) outside of Pink Taco this weekend. After first giving his blessing to Miley Cyrus and her burgeoning twerking career ... Wiley put the kibosh on Walker's fighting one.

As Wiley put it, "Let it go. I would hate to see Herschel Walker make it through all he's been through and now get crushed in UFC."

But Wiley did say HE could dominate the UFC and even threw down a challenge to a certain UFC star no one should ever mess with.

Tread carefully, Marcellus ...

​If Anderson Silva WANTS Roy Jones Jr., he's gonna GET Roy Jones Jr. -- 'cause RJJ tells TMZ he'll accept Spider's challenge to a boxing match ... but the clock's tickin'.

We spoke to the 44-year-old former boxing champ in L.A. this week ... who says he heard Silva loud and clear when Anderson told the New York Post about his dream to fight a "great champion" like Jones.

38-year-old Silva is currently under contract with the UFC ... but suggested that UFC honcho Dana White should strike a deal to make the fight happen.

As for Roy -- once considered the best pound-for-pound fighter on the planet -- he tells TMZ, "I would love it ... Call me and we'll make that happen."
