Fitness & Exercise

Canelo Alvarez isn't wasting any time getting his body ready for Gennady Golovkin.

The boxing superstar showed off his physique at the end of a workout this week -- and shocker, dude looks good.

Of course, Canelo and GGG are set to throw down in September in what boxing experts are saying could be the best fight of the year.

Joe Jonas and Sophie Turner are working out as a couple ... literally.

Paps spotted the pair holding hands as they left a gym sesh together Saturday in the East Village in NYC. As you can see by their workout gear ... things are getting physical between them.

We already know Joe's super athletic -- he boxes and whatnot in his spare time. Looks like he's getting Sophie into that ultra fit life too.

Plus, she's already made it clear Joe's giving her that good good. So again ... get it, Sophie!

Zlatan Ibrahimovic vows to return to professional soccer after his recent knee injury -- and he posted a photo of his insanely vascular legs to make his point.

The Manchester United star destroyed his knee Thursday -- and the team is describing it as "significant ligament damage." There are reports it's so bad, the 35-year-old might never play again.

But Zlatan says that's a bunch of crap ... he'll be back.

In a social media post, Zlatan acknowledged he'll be "out of football for a while" ... but added, "I will go through this like everythings else and come back even stronger."

Prince William might be royalty, but he's not above a good squirt in the face ... especially when he's on the front lines of a marathon handing out H2O.

William and Kate were at the London Marathon Sunday, being good citizens and handing out water to runners -- and this is the thanks they got.

At least the unknown practical joker had the decency to avoid the Duchess's mug.

We're guessing Will was a good sport about it. He's been known to be a happy-go-lucky future king from time to time.

Fluffy to Buffy? Gabriel Iglesias says that's the plan, and even though he's boxing to get it done ... do NOT call him the Mexican Butterbean!

We caught up with the comedian Friday at LAX, where he gave us a weight loss update. Remember, Fluffy canceled a few tour dates and rearranged some others to focus on his health. He took up boxing and says he's already had double digit success.

Gabriel flexed his new muscle for us, dropped a few jokes about his fitness regimen ... but also had a message for anyone else struggling with demons.

Oh, and since he brought him up -- take us out, Butterbean!

Serena Williams' baby will be one the most physically gifted super-athletes of ALL TIME ... so says Glen "Big Baby" Davis.

Here's the deal -- Serena is arguably the greatest female athlete who ever lived. Her fiance, Alexis Ohanian, is 6'5" and smart (he's one of the co-founders of Reddit).

And with their super-DNA combined, Davis says he's convinced the result will be an ultra-smart, ultra-talented, insanely gifted Bo Jackson-style baby.

Boston marathon bombing survivor Adrianne Haslet was deeply offended over a makeshift memorial that was placed at the WRONG SPOT this weekend ... calling those responsible, "F**king a**holes."

Haslet lost her left leg in the 2013 blast and returned to Boylston Street over the weekend -- only to see a wreath incorrectly placed in front of a Starbucks instead of the old Forum restaurant, one shop over.

"Nice work, Boston," Haslet said sarcastically ... "Real good job of laying the wreath in front of the wrong place. That's real offensive to everyone. Appreciate it."

Haslet ended up taking the matter into her own hands and moved the wreath to the correct spot.

She added this comment -- "I bet if we had a permanent memorial people would remember where the actual attack happened."

Haslet famously returned to the course last year -- as a runner -- and completed the race with a prosthetic leg.

Richard Simmons is "perfect," and "happy," but he's still dealing with a knee problem that has kept him in virtual hiding for the last 3 years ... that's the takeaway we got from one of his closest friends.

A woman named Denise -- who says she's known Richard for 35 years -- was at Richard's gate delivering flowers where she said the former fitness guru is doing great.

But then she says Richard's been dealing with a medical issue for years -- his knee. TMZ broke the story back in November, 2014 -- 8 months after Simmons just disappeared -- that he had 2 bad knees and an operation on the first was so painful he was delaying the second.

It seems that based on what Denise is saying ... Richard was bedridden for a time because he never got the second knee operation. Unclear if he's gotten it done yet.

Floyd Mayweather took his rain-makin' abilities from the strip club to the basketball court Thursday night ... and the champ had no problem cashing in.

Floyd posted the video showing off his solid jumper ... knocking down 6 straight shots with ease.

Great news for Sacramento Kings star Rudy Gay -- his recovery from a torn Achilles injury is going GREAT ... with Gay telling us he's 1 MONTH ahead of schedule!

As we previously reported, Rudy ruptured his tendon in a game against the Pacers on January 18 and underwent surgery a few days later.

Obviously, the Kings' season is over and Gay won't be in the NBA playoffs -- HOWEVER, he could choose to become a free agent on July 1st and sign a fat new longterm contract with another team.

So, when Gay says he's feeling great and should start running soon -- he's really probably talking to other teams ... letting everyone know he'll be healthy and worth every penny!!!

Paris Hilton headlining in Ibiza ... but she will also volunteer for a rager during a yoga sesh at Equinox, when it benefits a kid's charity.

Paris put her turntable skills to good use Wednesday at an Equinox gym in West L.A., where she was performing at a benefit for The Felix Organization, which helps children in the foster care system.

Bella Hadid will beat your ass in the ring, but you'd probably enjoy it.

The model slipped on the mitts in NYC for a boxing workout with a trainer. This was no photo shoot ... Bella looked serious about the session, and definitely dressed for the occasion.

Her bosses at Nike will be thrilled.

Our only question: Where's the headgear?? Protect the moneymaker at all times, Bella.

UFC star Dominick Cruz had to go radio silent recently during a secret trip to various U.S. military bases across the globe -- where he got to train soldiers how to punch and kick like an MMA fighter.

Conor McGregor's coach says the UFC star has already begun training for Floyd Mayweather -- because Conor truly believes the superfight will go down sometime THIS YEAR.

John Kavanagh joined "Bill and Boz" on Fox Sports News 500 and revealed while "the people in the suits" work on the contracts, Conor's in the gym training for a boxing match.

"In my mind, it's on. That's the mentality we're in," Kavanagh says. "As far as I'm concerned, I really believe it's gonna happen this year."

Kavanagh says training for boxing is MUCH different than training for MMA -- "It's simpler, less skills involved" -- but Conor's up for the challenge.

Jen Selter's Mexican vacation hot streak continues!

The hot-bodied model took her famous ass for a swim in the Caribbean Sea ... and it was muy bueno!!!

No sign of James Maslow this time around. We're told they're not dating ... they just met at a Maxim event and hung out with friends.

Mark Zuckerberg hit the gym hard Friday morning with his personal trainer ... his 16-month-old daughter, Maxima ... and she kicked his ass pretty good!

The Facebook honcho strapped Max (who we're guessing weighs about 25 pounds?) to his back for a set of pull-ups (he got 5) and some push-ups (he got 14).

Zuck commented, "As soon as I finish she yells 'More! More!' Easily the most demanding trainer I've ever had."
