Who needs the gym ... when you've got a beach?

Here's Sports Illustrated cover model Nina Agdal gettin' in some up-downs ... in her bikini ... while out in the Dominican Republic.

Nina's known for being an animal in the gym -- here she is pushing around more than 500 pounds on a sled earlier this month.

Prince William and Kate Middleton strapped on their hiking boots and climbed the Himalayas during their India '16 tour.

The Royal couple is halfway up Paro Taktsang, famously known as the Tiger's Nest Monastery.

Rob Kardashian has lost at least 50 pounds ... and he says he's now halfway there.

Ovince St. Preux says he "humbly accepted" Daniel Cormier's offer to train him for the Jon Jones fight at UFC 197 ... but only in a small guest trainer capacity.

OSP appeared on the "TMZ Sports" TV show (airs tonight on FS1) -- and told the guys he knows D.C. and they're "pretty cool" ... but wants his current trainer Joey Zonar to continue leading his training program.

So, how exactly would Cormier contribute? Check out the clip.

By the way, there's A LOT more in the full interview -- including OSP's thoughts about Jon Jones' legal issues.

Here's video of Serena Williams teaching a bunch of random people how to twerk while wearing skin tight athletic wear.

Here's proof 47-year-old Will Smith still has it in the squared circle -- video of the Fresh Prince getting some in-between takes work with a woman ... who could probably really kick his ass.

Will is in NYC filming "Collateral Beauty" and took a break from set to duck into the Overthrow boxing gym ... for some light sparring with WBC women's champ Alicia Napoleon.

Check out the clip ... Smith looks like he hasn't forgotten the moves he learned on "Ali" ... pulling off a perfect rope-a-dope. We're told he also hit the heavy bag a little while he was there.

Rumble middle aged man rumble.

Rob Kardashian unwrapped the best gift of his 29th birthday -- with a little help from Blac Chyna -- late Thursday night ... some In-N-Out!

The couple hit the drive-thru of one of the famed L.A. burger joints around 11 PM for what we hope was a burger and fries. As we've reported, Rob and Chyna have said "no cheat days" on their fitness kick.

But c'mon ... ya gotta indulge on your birthday, right? We're rooting for a double-double ... animal style.

Let the man live!!

A waist training corset made enormously popular by the Kardashian girls is now on the receiving end of a lawsuit by a bunch of women who say they got burned but their fat didn't.

The women are griping over Waist Gang Society, the company that manufacturers the Reshaping waistshaper.

The company touts that the product "burns fatty tissue by making you sweat, targets the back, torso, waist and abdomen areas."

The Waist Gang Society's website features countless photos of Kim, Kourtney, Kylie, and Khloe wearing the corset. The girls, who were not sued, sing the praises of the product on social media.

The lawsuit claims the advertising for the product is misleading, quoting a doctor who says, "Corsets do not cause you to permanently lose fat in the midsection: they cause a re-distribution of the fat and organs in the trunk." It promises to give consumers an hourglass figure, but it seems for the women suing it's mission not accomplished.

What a waist.

Forget the NBA, Lakers rookie sensation D'Angelo Russell might not be the best athlete in his OWN RELATIONSHIP ... 'cause his GF is showing the world she has some serious lift.

Russell is dating USC volleyball player Niki Withers who must've wanted to prove to him she knows her way around the basketball court ... 'cause check out this clip of NW grabbing the rim with authority.

It's pretty impressive video -- Withers is 5'10" (and the sister of Jaguars TE Marcedes Lewis) and glides up to the cup with ease.

We would say she should try out with the Sparks ... but let's face it ... the Lakers need more help.

He's definitely slimmed up ... but Eddie Lacy says he refuses to put an exact number on his weight loss because "I don't do scales."

The Green Bay Packers RB touched down at LAX this weekend -- so, we had to ask about his off-season workout regimen with P90X creator Tony Horton.

Lacy says he's feels great ... and he doesn't need a stupid scale to prove it.

But at some point, the Packers are gonna make him get on a scale right??

Richard Simmons broke his silence to shoot down a report that his long-time housekeeper is holding him hostage in his home.

Richard appeared on "Today" Monday via telephone, acknowledging he's dropped out of sight for years but he's ok.

The New York Daily News did the latest story over the weekend -- that Richard's friends have been alarmed that he has shut down contact with them.

TMZ has reported over the last year-and-a-half, Richard has shut close, long-term friends out of his life. He doesn't acknowledge birthdays, deaths and various forms of outreach by people who love him.

As we reported, in January of last year the LAPD went to Simmon's home for a welfare check after a friend reported he was the subject of elder abuse. The LAPD cops say Simmons looked fine and was in good spirits.

You can hear in the "Today" interview ... he's dealing with issues.

Vince McMahon is such a BEAST in the gym, even his own musclebound son-in-law refuses to hit the weights with the guy ... telling TMZ Sports, "He's too crazy."

We got Triple H and his wife Steph McMahon out in NYC -- and we asked 'em about their famous midnight workouts ... and how the hell they muster up the energy to train that late at night!!

That's when we brought up 70-year-old Vince -- who's legendary for crushing it in the gym -- and Triple H told us the rumors are true ... the guy is an absolute "machine."

We also got Vince's wife Linda McMahon who told us Vince pumps iron at least 5 days a week ... and when stacked up against HHH and his son Shane ... "He would put 'em all to shame!"

#BEAST

Rob Kardashian's confidence is back ... and we know this because his shirt was gone during a backyard hang with Blac Chyna.

Rob stepped outside half naked ... giving us a first glimpse at his bod since he started his diet and fitness regimen. Chyna shot video of him Wednesday afternoon as he peered down at her grilling a ton of grub.

As we first reported ... Rob's already down at least 40 pounds, but it's been hard to notice, since he's still sporting a lot of baggy clothing.

She's about to be suspended from the court ... but Maria Sharapova still has the beach -- and today, she grabbed her racket to hit some balls on the sand.

Despite the fact Nike suspended her deal in the wake of her failed drug test, Maria was sporting Swoosh pants and shoes on an L.A. beach Wednesday afternoon ... with a smile on her face.

Maria admitted she tested positive for a banned substance at the Australian Open back in January -- and the International Tennis Federation has announced she'll be provisionally suspended starting March 12th.

In the meantime, might as well get a tan right?

L.A. Rams WR Stedman Bailey is back in NFL training mode -- busting his ass in a Miami gym in the hopes of returning to the league despite being shot in the head ... and TMZ Sports has the video.

Bailey was struck by two bullets on November 24th ... leaving him in critical condition at a Miami hospital ... where he remained for a month.

S.B. vowed to make a gridiron comeback ... despite the odds being so incredibly stacked against him.

Now, we've learned the former 3rd round pick has been hitting the weights hard at the Xtreme Fitness gym in Miami ... and according to the owner Gary Sanchez, he's making tremendous progress.

"He's been training with me for 2 and a half months," Sanchez says ... who's been working with Bailey on weight training, balancing, hand-eye coordination and explosion movement drills.

"My biggest fear was, 'Is he mentally going to be ready and has he lost any type of functions?' But he didn’t. He was ready to go the minute he walked in the gym."

As far as his NFL future goes ... Bailey's trainer says, "He is physically and mentally ready, definitely ready to go right now."

Jared Fogle is a lot of things ... but one thing he's not is fat.

Fogle has reportedly been on a downward dietary spiral at Englewood prison in Colorado ... supposedly heavier by 30 lbs and counting, courtesy of the prison commissary.

Fogle's attorney, Ronald Elberger, tells us it's all a lie ... his client hasn't gained a pound in prison ... to the contrary he exercises regularly on the prison track.

He's eating standard prison fare, including soups, burgers, beef stew, BBQ chicken and enchilada casserole. There are reports he's scarfing down Honey Buns ... Elberger says not true.

The lawyer says Fogle is actually doing quite well in the first few months of his 15 year sentence.
