Fitness & Exercise

There will be no puff and pump for James Woods ... 'cause the Hollywood legend says Ricky Williams' new weed gym is a terrible and dangerous idea.

Wanna REALLY kick someone's ass? Pay attention ... Master Van Damme will teach you.

Gucci Mane may have lost his freedom by doing time, but he also lost a ton of weight ... and he'll continue with his prison diet to keep his abs tight and the lbs off.

Gucci dumped 50 pounds behind bars by staying clear of carbs. It helped that he couldn't booze it up. He believes a no-carb diet is the key and he will carry that forward during his house arrest. Interesting ... we can't get a clear answer on whether Gucci will hit the bottle again.

The rapper knows exercise is critical, so he'll continue his prison regimen of sit-ups and weights ... just at a 24 Hour Fitness instead of the yard.

Gucci's so serious about his new physique he turned his nose up to cake and booze for his coming home party ... so says his lawyer, Drew Findling. He stuck to chicken and agua.

Here's Hafpor Julius Bjornsson -- better known as "The Mountain" from "Game of Thrones" -- pulling a 17-TON BIG RIG in Iceland like it was a Tonka Truck.

Eddie Lacy went all Rocky Balboa (from "Rocky IV") in his off-season workout -- training in the snow TWICE A DAY with his P90X trainer Tony Horton.

Horton -- who created P90X -- spent months helping the Green Bay Packers running back trim down for the season ... and judging by the last video we shot of Lacy, it worked. Dude's pretty ripped now.

So, we asked Horton how he got Lacy back to form -- and the training regimen he revealed is pretty hardcore ... including some snow shoveling sessions in Jackson Hole.

Horton says Lacy was a natural when it came to working out -- but there was ONE exercise the guy couldn't stand.

The beast is (almost) back!

John Cena says he's making insane progress in the gym since undergoing shoulder surgery back in January ... telling TMZ Sports he's at 70% ... but vows to be back at full strength VERY soon.

The WWE superstar was out in NYC with his girlfriend, Nikki Bella, when he told us he's been putting in serious physical therapy work in hopes of a full recovery.

"I'm probably 30% off of what I was operating at November 2015 ... but being at 70% is still pretty damn good."

He also gave a shout-out to his strength trainer -- Rob MacIntyre at Hard Nocks South ... the same guy who pushed him to bust out a 481 POUND BENCH PRESS back in the day.

Mike Vick says he's training his ass off to return to the NFL ... with his rep telling TMZ Sports the QB would love to stay in Pittsburgh, but he's open to playing for any team in the league.

Earlier this month, Vick told reporters he's got "one more dedicated season in my blood" -- but also said he'd be okay if he didn't get picked up by a team in 2016.

Well, we're told Vick is still preparing as if he will play in '16 -- "He's training every single day. [He's] staying ready mentally and physically."

When asked if he had any preference, Vick's rep told us he loved playing in Pittsburgh "but he'll be ready wherever he goes."

Vick is currently a free agent -- but his rep reminded us that he didn't get picked up last year until the end of August ... so he's not sweating it yet.

Johnny Manziel says he's like Rocky in "Rocky IV" when it comes to training -- climbing some insane mountains EVERY SINGLE DAY so he can get back in the league.

We got the QB leaving lunch at King's Fish House in Calabasas (no, it's not a nightclub) ... and asked with all of his partying, when does he make time to train?

"Every single day," Manziel told us ... before pointing to the mountain range and telling us he's been getting in work by climbing the hills.

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.
