He's been out of the NFL for 2 years ... but Braylon Edwards is CRUSHING IT in the gym -- turning himself into a monster ... and he insists he's 100% roid-free.

Edwards has basically been living in the gym and working out with a hardcore crew. He looks bigger than he ever was during his time in the league.

Unclear if the 32-year-old is training for a comeback (unlikely after 5 knee surgeries) or just enjoys getting his pump on ... but he insists he's au naturel.

"I don't take roids I work out everyday no exceptions no excuses."

Exhibit A for dudes to get into a yoga class -- Colin Farrell dripping sweat after getting his tree pose on ... probably some downward dog too.

Colin air-dried on his way out of class Monday in West Hollywood. Yoga seems to be his workout of choice lately -- he's been spotted leaving classes all year.

Khloe Kardashian's made a full recovery from a staph infection because she was back to her regular workout regimen.

Khloe hit SoulCycle Sunday in Bev Hills to burn some calories. She seemed to enjoy the workout, but remained quiet when our photog asked about Lamar.

It's the first time we've seen her back to her usual routine since she was diagnosed. Makes sense ... a sweaty gym environment is NO place to fight off staph.

Besides her regular workout, Khloe's also back to sporting the Adidas logo -- a clear sign, it's back on with James Harden.

Alessandra Ambrosio reached deep into her closet over the weekend and dusted off her rollerblades to exercise at the beach in Santa Monica.

If anyone can make rollerblading a thing again, it would be her. Or more accurately ... her ass.

If you're wondering how Bradley Cooper gets his rock hard bod and lands hot chick after hot chick, this video of him with his boxing gloves on pretty much explains it.

Brad got some pointers in the ring from a trainer Monday morning while working out at Gotham Gym in NYC. It looks like he's really learning the tricks of the trade, especially the ole stick and move.

We looked, and he doesn't appear to have any boxing roles in the works ... so this could just be him getting a jump on his holiday calorie burn -- or a way to impress a new chick.

D-Wade's been workin' out.

The Heat superstar got his swoll on during a training session at DBC Fitness in Miami last week -- rippin' out a set of reverse grip cable flys ... and dude looked ripped.

Front's not too shabby either.

Answer: Hemsworth ... after he dropped major lbs for his starring role in Ron Howard's upcoming "In the Heart of the Sea."

Hemsworth plays a sailor stranded at sea in the Moby Dick-inspired flick, so he obviously got way into character. He posted the throwback pic from the set saying he wouldn't recommend the diet to anyone.

Hard to believe that's the same guy who plays Thor, but the good news is Chris is back to his standard beefy bod since filming.

Mama June has hard evidence she's trimming down her waistline ... she's back to wearing blue jeans!

We got June arriving at LAX with a friend, and while it was clear she'd continued her pattern of dropping lbs -- we didn't know just how much ... until her friend pointed out June's new wardrobe.

The "Here Comes Honey Boo Boo" matriarch was rocking some distressed denim, and says it's been years since she zipped up a pair.

Busta Rhymes did much more than just throw a protein shake during that fight in a gym -- surveillance video now shows him totally losing it on an employee!

The incident went down in August at Steel Gym in NYC ... and the video, first posted by Page Six, shows Busta in some kind of verbal dispute with the employee who's sitting behind the front desk.

At some point the rapper gets tired of talking and throws a liquid at the man, then clears the counter top ... taking out everything in front of the guy ... including his computer monitor.

Now we know how 50 Cent keeps his body so swoll -- he drops a fortune to keep a trainer by his side nearly 24/7.

In fact, according to docs filed in his bankruptcy case obtained by TMZ ... the rapper pays more than $3k a month in workout expenses. A big chunk of that -- $2,800 to be exact, goes to his trainer, Jay Cardiello.

Jay has talked about working with 50 before, saying he pretty much eats, sleeps and breathes with 50 ... since they train together 3 times everyday.

And get this, despite the fact 50 hasn't had a #1 hit on Billboard's Hot 100 since 2003 ... he still makes $36k per month in royalties.

Britney Spears gave a bunch of dancing queens a huge surprise when she commandeered their class, and choreographed a new routine for them.

Fern Adair, the owner of a Vegas dance studio, says Britney's people contacted her a couple weeks ago, and said Brit wanted to reconnect with her dance roots. Just a few days later, Spears showed up to a class filled with kids aged 8 to 18.

We're told she spent an hour teaching them some steps to Pharrell's "Happy."

So, mission accomplished. Roots connected.

Some people spend hours at the gym ... Eva Longoria dances like a Pussycat Doll.

Eva flew to Mexico recently for a dance fitness retreat run by founder and choreographer Robin Antin. It's more of a sexy aerobics boot camp where they tried out the new PCDFIT weighted fitness gloves ... Antin tells us they were inspired by UFC fighter Ronda Rousey for an added kick-ass element.

Eva nails the intense routine, which clearly yields great results.

Kate Upton banged out a set of squats during a workout in West Hollywood with her personal trainer, who kept a watchful eye on ... her form.

Yes, he's actually getting paid to do this.

Rob Gronkowski wants to be the Tom Brady of gym equipment -- THE KING -- and now he's launched his own line of fitness products to take you to Jacked City.

The entire Gronk family is involved in Gronk Fitness ... selling everything from push sleds to battle ropes, squat racks and more.

Turns out, Gronk's dad used to own fitness retails stores and spent 25 years in the business -- and since his kids are bona fide muscle heads, they decided to put together their own gym equipment company.

We spoke with Rob's brother, Dan Gronkowski, who says the idea came about last year -- "We said if Rob wins the Super Bowl, we'll do it. And he did. So we did."

Dan says all the stuff is commercial grade quality -- "This isn't us slapping our names on some crappy product, this is quality stuff."

And the family is dead serious about growing the business -- "We want to be the place to go to for athletes and gyms."

Bob Harper thinks it's a stroke of genius on Weight Watchers' part to team up with Oprah, because she's a 10 on the relatability scale.

We got "The Biggest Loser" trainer leaving Brick CrossFit in West Hollywood Monday, after Weight Watchers' stock doubled on the heels of the announcement Oprah now owns 10% of the company's stock and will sit on its board.

Josh Gordon has been hittin' the weights ... hard ... killing himself to get ready for his NFL comeback in 2016 -- and judging by the footage of his workouts, dude looks ready to go.

The Cleveland Browns wide receiver was suspended for the 2015 season for violating the substance abuse rules -- but he's vowed to make a comeback and it looks like he's taking things seriously.

Gordon's agent Drew Rosenhaus previously told us the 24-year-old is keeping his nose clean and "doing all the things he has to do to get ready. We fully anticipate him being back for the 2016 season."
