Fitness & Exercise

Ex-NBA player Al Harrington says Zion Williamson should do one thing if he wants to have a long career dominating on the NBA level ... and that's lose about 20 pounds.

Zion has the Internet going nuts right now ... with his crazy dunk videos (including a free throw line joint) from Duke practices going viral because of the sheer amazingness of his athleticism.

But, Williamson is physically MASSIVE ... with reports saying all that jumping ability is coming from a guy who weighs upwards of 280 pounds.

Harrington says that's fine for now, but if Zion wants his body to withstand the night-in, night-out grind that is the NBA, he might wanna shed a little.

"I think in order for him to have longevity in the league, he'd have to lose like 20 pounds maybe."

Harrington goes on to say that Zion should learn from guys like LeBron, who've had to slim down in order to add years to their careers.

Al knows what he's talking about, he was a beast for 16 years in the NBA ... but if you look at the video below, the kid looks alright. Like, DAMN.

BEAST!!!

Here's Matt Stafford's very pregnant wife, Kelly Stafford, gymin' for 2 in Detroit this week -- rippin' off set after set while 38 weeks preggo!!!

Kelly (who's pregnant with baby #3) hit up Elite Training USA and crushed everything from the battle ropes to the weight sled and even some modified deadlifts!!!

Kelly is calling the routine, "Operation GET BABY OUT."

Meanwhile, Matt's working pretty hard too -- gearing up for the NFL season with the Detroit Lions.

Kelly is technically due in 2 weeks -- but she's at full term now and clearly she's ready to celebrate a birthday.

Jada Pinkett Smith's new friend is a shredded 72-year-old bodybuilder who is fit to DESTROY Will Smith ... in a push-up contest!!

We talked to Dr. Josefina Monasterio whose determination for body wellness is giving Jada all the feels. We're not sure big Willy will feel the same way as his wife though, now that Josefina's calling him out and challenging him in the gym.

Check it out ... the good doctor has more than push-ups in mind for Will -- and says now that she has Jada's digits, it won't be easy for Will to dodge her challenge.

If you're wondering how she and Jada connected -- Jada recently reposted one of Josefina's videos to her Instagram feed. Some of Jada's fans mistook Josefina for Jada's mom, Adrienne Banfield-Jones (she's not) ... they're both super fit. Anyway, they both set the record straight with a FaceTime hookup.

8:55 AM PT -- Jax just replied to our story, saying, "Come on it’s kind of funny, wasn’t trying to be a dick. It happens to be best of us. Drake should make a song though 'started at the top now we here'. Maybe next album?"

"Vanderpump Rules" star Jax Taylor took glee in watching Younes Bendjima slum it like all the normies after Kourtney Kardashian dumped his ass.

Jax posted this photo Monday night at an L.A. gym, as Younes contemplated his water bottle and his next exercise.

TMZ broke the story ... Kourtney pulled the plug on her relationship with the 25-year-old model last month ...shortly after their trip to Italy.

Jennifer Lopez and Alex Rodriguez got steamy on a luxury yacht ... with some pull-ups, kettlebell swings and a full-on workout WHILE ON VACATION!!

J Lo and A-Rod were sailing off the Amalfi Coast and squeezed in an intense workout ... proving yet again there's no excuse ya can't bang out a workout sesh while on vacation. A-Rod got so sweaty ... he took off his shirt and showed off his Hall of Fame-worthy bod.

One great way to cool off ... a dip in the ocean, of course. J Lo snapped a selfie before taking a leap and A-Rod followed suit, albeit with a little less flair. The couple wasn't alone -- J Lo's manager, Benny Medina, also joined them on the trip.

Seems Jennifer and Alex love their boats, and we can't blame them. They were on Miami heat owner Micky Arison's legendary Sirona III just the other day. Again ... it pays to be rich.

Did you know Andrew Luck was jacked? We didn't ... until now.

The Indianapolis Colts QB was flexin' a legit 6-pack Thursday night in the locker room after his pre-season game against the Seattle Seahawks ... a game where he went 6-9 for 64 yards.

It was Luck's first NFL action since 2016 -- but just because he missed playing time doesn't mean he missed the gym ... at least judging by the video.

Luck was standing behind coach Frank Reich -- who was talking about the importance of getting better every day -- and proved he's been doing that when it comes to his physique.

If anyone thought LeBron James was going on the California Diet to get all skinny now that he's a Laker, YOU'RE WRONG, 'cause here's a pic that proves his muscles are still of the Ohio corn-fed variety.

Here's LeBron shooting around with his teammates in purple & gold practice gear, and the dude looks MASSIVE.

Along with Bron, Brandon Ingram and some team trainers were also in the building watching King James work. It's the first time we've seen Bron in his Lakers practice gear since he signed his contract.

With all the big Hollywood deals he's been making lately -- along with launching a school in Ohio -- it's good to see him making time for some hoop.

Everyone knows LeBron's a workout warrior, and with the way people have been coming at him lately, it might be a good idea to break out the guns and show he's ummm ... different.

If you wonder how he does it ... check out the INSANE video below.

It looks like KFC's found its next Colonel Sanders -- The Mountain from "Game of Thrones" ... and he's in the Colonel's duds doing something very Mountain-esque.

TMZ got video of Hafthor Julius Bjornsson -- aka Thor, the 2018 World's Strongest Man -- decked out in the famous white suit for a one-of-a-kind video shoot ... for the record books.

We're told it was a success, and along with also being a 4-time Europe's Strongest Man winner and a 7-time Strongest Man in his native Iceland ... he now holds the record for pulling the most fried chicken!

That's finger lickin' impressive.

It's unclear if The Mountain's officially joining the club of actors turned KFC spokesmen like Darrell Hammond, Norm Macdonald, Jim Gaffigan, George Hamilton and Rob Riggle, but if he does ... he'll easily be the strongest of the group.

Todd Gurley celebrated signing a four-year, $60 million contract extension Tuesday by going ALL OUT ... in the weight room.

The Los Angeles Rams tailback -- and now the richest-ever RB in NFL history -- didn't take a day off to enjoy his fat new paychecks ... and instead decided to get some shoulder work in.

Todd pressed some heavy-ass kettle bells and got in some footwork drills ... not exactly ballin' out on fillets and champagne.

Of course, training camp starts Thursday ... so the celebration might be on hold for a while.

Khloe Kardashian's secret to dropping tons of lbs since giving birth includes resistance bands, BOSU balls, a healthy diet and ... TRUE THOMPSON!!!

We spoke to Khloe's trainer, Don Brooks -- aka Don-A-Matrix -- who tells TMZ ... Khloe's success to sweating away 33 pounds has everything to do with True's mere presence near the end of her workouts when she needs an extra boost. Seriously.

Can't knock the scheme when it's obviously working wonders on Khloe. Sure, Don's innovative workouts coupled with two-a-days have done their magic ... but it's crystal clear Khloe draws tons of inspiration from her cute, 3-month-old daughter.

Here's Cristiano Ronaldo looking like Ivan Drago in "Rocky IV" -- hooked up to all sorts of machines as he takes his official medical exam for that massive Juventus deal.

CR7 arrived to the Juventus medical facility near Turin, Italy on Monday ... ready to work.

Sporting a mesh shirt and massive diamond earrings, the soccer superstar hit the treadmill as part of the exam ... which will ensure that Ronaldo is in the world-class shape Juve expects him to be.

Cristiano didn't seem worried -- cracking a smirk as he began to exercise.

It's a big day for Juventus -- which paid a $117 million transfer fee to get Ronaldo from Real Madrid. Plus, the team is reportedly paying him around $35 MIL per year.

Sage Northcutt tipped the scale at 170 lbs. on Friday ... but he'll be a helluva lot heavier in the future -- as in, the size of a 206+ lb. heavyweight -- 'cause that's where Super Sage says he'll eventually fight.

TMZ Sports talked to the UFC star before his co-main event fight against Zak Ottow at Saturday's UFC Fight Night 133 -- a fight in the 170 lb. welterweight division.

That's a step up for the 22-year-old -- who's been fightin' at 155 lbs. -- but it ain't the final destination.

"Personally I think I might end up fighting heavyweight in the future," Sage tell us.

"I can just see myself keep growing. I'll be 24, 25, growing 2, 3, 4 more inches, and putting on a lot of muscle. I can absolutely see it."

Is Tekashi69 the best soccer goalie to ever live??

Well, Tekashi69 sure as hell thinks he is ... telling TMZ Sports NOBODY -- including Cristiano Ronaldo -- can score a goal on him.

And, he's being 100% serious.

We spoke with the "Gotti" rapper about his goalkeeping skills after he put on a display in a workout video earlier this week ... and Tekashi says Brazil's lucky he won't be between the posts in their World Cup match with Mexico on Monday.

In case you need a refresher, Tekashi showed he's actually a pretty solid keeper, given the fact it's a small goal and he's going up against a bunch of kids (but the footwork probably needs some help). He did, however, do decently against Italian soccer star Mario Balotelli.

Mama June has taken her fitness regimen to the next level ... lounging on a sofa and even showing some underboob for her TV show.

June posed in some pretty skimpy lingerie -- at least that's what the show is calling it -- for her show, "From Not to Hot."

Richie Incognito tells TMZ Sports he's feeling good and doing well after a turbulent offseason ... and now he's seriously considering an NFL comeback.

Over the past few months, the NFL lineman was involved in a bizarre gym altercation and also dealt with threats from his former Miami Dolphins teammate, Jonathan Martin.

Richie says he's been trying to relax and meditate, and feels he's in a much better place in his life. He also tells TMZ Sports he's praying for Martin, who he still considers to be a friend.

"I wish nothing but well for him."

Richie says he's also working to put a spotlight on mental health to help people who need it.

As for his football career, Incognito "unretired" back in April and tells us he's "excited about the opportunity to come back."

Todd Gurley was maybe the only human on the planet unimpressed by Aaron Donald's 495-pound bench press this week ... 'cause the running back says that's LIGHT WEIGHT for him.

Is he joking? Maybe (probably) ... but the clip's funny anyway.

The Rams star was leaving Craig's in West Hollywood this week when he told us 495 is easy work ... because he's been pushing up OVER 500 pounds!!

Again ... he's gotta be kidding, right?

FYI ... Todd weighs 227, Aaron checks in at 285.

By the way, the strongest NFL running back we've ever heard about is Napoleon Kaufman -- a gym freak who reportedly put up 500 pounds on the bench back in the day.
