Tony Gonzalez is still giving back to the Chiefs -- training one of the team's young tight ends who's currently wearing TG's 88 jersey!!!

The future Hall of Famer rolled into Jay Glazer's Unbreakable gym in L.A. this week to train up Ross Travis -- a former Penn State basketball player who signed with K.C. in 2015 in the hopes his skills can translate to the football field.

Tony and Ross went over blocking techniques -- while Sylvester Stallone was right next to the guys doing his own training regimen.

By the way, Ross didn't do much on the field last season (playing behind stud Travis Kelce) but he killed it in locker room basketball trick shots.

Here's Alex Smith finally proving he has something Petyon Manning, Tom Brady, and Ben Roethlisberger don't ... muscles ... showing off his All-Pro physique on vacation.

While rumors swirl over Tony Romo taking his job, Alex is down in Hawaii canoeing, and from the look of these pictures, probably not eating much bread.

Joe Mixon just dominated at Oklahoma's pro day -- posting VERY impressive numbers in various drills -- but the question remains ... will an NFL team actually pull the trigger in April?

Obviously, Mixon's past is a huge red flag -- he wasn't invited to the NFL combine because of the video showing him brutalizing a female student in 2014.

Instead, Mixon put his skills on a display at a special workout on the Oklahoma campus -- putting up numbers that would put him in the Top 10 against other RB prospects in almost every category.

Mixon reportedly posted a 4.43 second 40-yard dash time (which would've been the 4th fastest time among running backs at the combine) and completed 21 reps of 225 pounds in the bench press.

Some experts say Mixon will still be drafted as high as the 2nd round ... others say he could fall out of the draft entirely.

Think John Ross' record-breaking 4.22 second 40-yard dash at the NFL combine was impressive??

Well, his speed coach says he coulda gone EVEN FASTER -- claiming he's certain the future NFL wide receiver coulda posted a 4.18 ... had he not cramped at the end of his run.

HE'S NOT KIDDING!!!

TMZ Sports spoke with Gary Cablayan of Evo Sports Training -- who Ross tapped for his pre-NFL speed training -- and he's warning NFL corners ... better ice up.

10 reps on the bench press is bad ... REALLY BAD ... so says Cleveland Browns stud lineman Joe Thomas who says Christian McCaffrey needs to hit the weight room HARD.

We just spoke with Joe about the NFL combine -- and asked the 10-time Pro Bowler if Christian's poor strength showing will affect his draft stock.

"As we all know, there's no bench press on the football field," Thomas said ... "For the most part, your film from every Saturday in the Fall is what should matter."

Thomas also reveals the one question rookies MUST NOT GET WRONG at the combine -- and it's actually pretty hilarious.

Plus, Joe also tells us about BBQ joint, Mission BBQ, and how it's taking over! Who's hungry?

Adrian Peterson is showing NFL teams he's still a FREAK IN THE GYM ... posting footage from a recent workout to prove he's still got the power and explosiveness to dominate in the league.

In the footage, AP knocks out 23 reps on the bench press -- it looks like he's pushing 225 lbs.

Then he grabs the squat bar -- loads it up with another 50 pounds -- and starts doing box jumps!

Peterson added a message -- "Not on a decline, rather an incline! 32 in a few weeks and still schooling!"

"The Biggest Loser" host Bob Harper's looking good following his major heart attack, and says he's taking steps toward recovery ... small ones with his dog.

The fitness guru's been posting pics letting fans know he's getting better, but says the only exercise he's allowed to do right now is walk Karl around the city and in the park.

We broke the story ... Bob suffered the heart attack 2 weeks ago and was unconscious for 2 days and hospitalized for 8.

Normally, he'd be competing in the CrossFit Open this time of year. Strolling with Karl's gonna have to suffice for now.

Justin Bieber is in a race to the bottom ... but at least now he's got some attractive company.

Bieber took a 1-on-1 hike with his model friend, Ashley Moore, who seemed down to get physical with him in a friendly competition running on a canyon trail.

If there's one thing we know about Bieber ... he tends to open up in the wilderness. Bodes well for Ashley. Plus they've hung out before -- couple years ago at a Clippers game -- so, seems like they've got a connection.

Jackie Warner's face was flush right after she was arrested for backing her vehicle into a cop car.

TMZ obtained the fitness queen's mug shot -- taken after the L.A. County Sheriff's Dept. took her into custody Friday night in West Hollywood.

We broke the story ... Warner crashed her car into a pole. A deputy on scene had to jump out of the way when she allegedly threw her car into reverse without warning.

Conor McGregor has been hitting the boxing gym with an Irish boxing sensation -- who tells TMZ Sports the UFC star is 100% confident the fight with Floyd Mayweather will actually take place.

We spoke with 25-year-old Michael Conlan -- who won an Olympic bronze medal for Ireland in 2012. Conlan says he became friends with McGregor a while back and the two have been tight ever since.

In fact, Conlan says McGregor has agreed to carry the Irish flag when Conlan walks to the ring during his upcoming pro fighting debut on St. Patrick's Day at Madison Square Garden.

In the meantime, both Conlan and Conor have been training together at an L.A. boxing gym -- as recently captured by TheMacLife.com.

We asked Conlan how McGregor's boxing training is going -- one thing's clear ... he's definitely impressed.

Michelle Obama put her legs -- and possibly those of her Secret Service agent -- through the paces Sunday in Washington, DC.

We got Michelle on her way out of SoulCycle. Looked like she had a decent workout, but check out the agent covering her. No dark suit and shades on this guy ... and based on his gear, we'd say he got in some cycle time too.

Our DC sources say Michelle and her Secret Service agents used to get private classes, but now she spins with the public.

Greg Hardy's training MMA at an elite gym in Florida ... but how does he look, and is he any good?

Now we know ... 'cause TMZ Sports has exclusive video of a Friday afternoon training sesh at American Top Team ... AND an interview with his training partner, Antonio "Bigfoot" Silva.

We asked "Bigfoot" Silva -- once one of the best UFC heavyweights -- about the prospects of his sparring partner making it at MMA's highest level ... the UFC.

Silva says don't be surprised if Hardy's fighting inside the Octagon within a year or two.

As for Hardy's kickboxing coach, Steve Bruno, the guy holding the mitt and pad while Greg works on combos -- jabs, crosses, knees, kicks -- he broke down the former Pro-Bowler's upcoming training schedule.

This is amazing ...

UCLA superstar Lonzo Ball accepted a dunk-off challenge from a fellow Bruin student ... and it ended with a KILL SHOT!!

It's great video -- non-collegiate athlete Kevin Wei (who's studying for his degree in Applied Mathematics/Computer Science) went to Pauley Pavilion for the 1-on-1 dunk-off.

Wei actually managed to DUNK ON BALL (yeah, it's a lowered rim but still!) -- and that's when Ball decided to exact some hardcore revenge with a windmill powerdunk.

R.I.P. Kevin Wei.

(But really ... props on the insanely cool video).

Looks like Kevin Love is off to a great post-surgery recovery on his left knee ... because the Cleveland Cavs star was already walking around the streets of NYC last night and TMZ Sports has the video.

Love underwent arthroscopic surgery on Tuesday in NYC where a doctor removed loose bodies from the knee. He's expected to be out around 6 weeks.

But Wednesday night, he was already moving pretty well on his way out of a Ralph Lauren fashion show with his girlfriend, Kate Bock.

It's great news for Cavs fans and Polo fans ... 'cause the collection looked dope!

WWE superstar Big Show has a message for Shaq -- a big, giant sweaty message -- GET READY TO GET YOUR ASS KICKED AT WRESTLEMANIA!!

Big Show has been training for their big showdown at WrestleMania 33 in April -- after months of smack talk.

Now, Big Show is showing off his progress with a gym pic and a message mocking Shaq who's been spotted at an Oreo cookie event recently and lip-synching on Instagram.

"@Shaq! Karaoke? Doughnuts? You better get serious. All roads lead to @WrestleMania. The only giant!"

You know what this means? SHAQ'S GOTTA SELFIE BACK!

If ever a video was gonna make you get up and get your lazy ass to the gym, it's this one ... 81-year-old golf legend Gary Player burning up a treadmill with all the AARP swag in the universe.

Player is notorious for his fountain of youth fitness habits, and even posed nude in ESPN The Magazine's Body issue at 77 ... but we gotta say, this might be even more impressive.

Look, is he Usain Bolt? No. Is he going harder than we do? HELL YEAH!!!
