Tarek El Moussa's flaunting his best fixer upper yet, and it ain't a house -- it's his ripped bod.

We're told the "Flip or Flop" star was super motivated to get fit after battling 2 cancers, recovering from debilitating back problems and, of course, his troubles with Christina.

Tarek wanted to show off his progress and posed for these seriously shredded pics. Dating site profile pic material?

One of the smoking hot models on "Amazing Race" knew she needed to toughen up for the show -- so she got in the ring with boxing champ Victor Ortiz!

Jenn Lee (see bikini pics below) says she hooked up with Ortiz back in June to work on her strength and conditioning for the race around the world ... and it paid off in a big way.

In fact, she's STILL training with the guy even though the show's in the can ... because, as it turns out, boxing training is great training for bikini season.

Not that she really needed the help ...

LA Fitness spas are so nasty and overrun with dangerous bacteria, sitting in one can put you in the hospital for a week ... according to a new lawsuit.

A New York man is suing the health club for $2.5 MILLION for allegedly giving him Legionnaires' disease -- which led to severe pneumonia -- after he used its spa on November 30, 2016. According to the docs ... the man became violently ill shortly afterward and ended up in the hospital for 5 days.

The man claims the spa was contaminated with Legionella bacteria because the club failed to keep it sanitary ... and the Nassau County Health Dept. found several violations in the spa and pool and shut it down.

The man's suing for making him sick and all his pain and suffering.

Gabriel Iglesias -- aka Fluffy -- put his tour on hold to save his life, and now it's clear what's he's been doing to get healthy ... boxing.

Iglesias canceled some stops on his hugely successful comedy tour earlier this month citing health and emotional issues. Well, now we've learned, Fluffy's been hitting the gym with celeb boxing trainer Ricky Funez and he's already dropped over 20 pounds.

At the time he stopped his tour, he weighed more than 360 lbs.

We're told Fluffy puts on the gloves 5x a week for 2 hours at a time ... putting in work in the ring and on the speed bag ... his goal is to shed 50 more pounds before hitting the road again.

Funez is no stranger to training celebs ... Justin Bieber, Floyd Mayweather and Mike Epps have all rolled through his Ten Goose Boxing in the valley.

Cue the 'Rocky' theme song!

Kesha went makeup-free at the gym in L.A. ... and sweat it out with some Pilates.

The singer sported a simple white tee Tuesday with "Bring it on Home" plastered on the front.

Orlando Bloom's leaving us in suspense with a new cliff-hanger ... by jumping off a cliff.

Orlando's in St. Barts with Kristy Hinze and her billionaire husband James Clark -- been there since Friday, actually -- and he's getting over Katy Perry in exhilarating fashion.

Dave Chappelle flexed his biceps in front of some huge stars at his Monday night concert.

Kanye, Kendall Jenner, Don Cheadle and Stevie Wonder were all front and center to watch Dave perform at The Peppermint Club.

On his way out Dave used his muscles to help a pap who ate it hard on the sidewalk.

BTW ... Dave's 2 new stand-up specials dropped on Netflix Tuesday. Soooo ... go peep that.

Ben Affleck was just like every other Los Angeleno Sunday trying to get around the L.A. Marathon, so of course ... he asked the paparazzi for directions.

The actor was out with his kids in the Pacific Palisades, when he realized he'd have to cross San Vicente Blvd. to head south ... but couldn't, 'cause it's part of the race course.

Who needs GPS when you've got eager paps standing by, and the exchange between them and Ben couldn't be more of a Southern Californian moment.

Ben, what are YEWW doing here?

Models Melissa Molinaro and Candice Craig took their squat workout to L.A.'s scenic Runyon Canyon, but we doubt anyone was taking in Mother Nature while these 2 made their way down the hill.

Tony Gonzalez is still giving back to the Chiefs -- training one of the team's young tight ends who's currently wearing TG's 88 jersey!!!

The future Hall of Famer rolled into Jay Glazer's Unbreakable gym in L.A. this week to train up Ross Travis -- a former Penn State basketball player who signed with K.C. in 2015 in the hopes his skills can translate to the football field.

Tony and Ross went over blocking techniques -- while Sylvester Stallone was right next to the guys doing his own training regimen.

By the way, Ross didn't do much on the field last season (playing behind stud Travis Kelce) but he killed it in locker room basketball trick shots.

Here's Alex Smith finally proving he has something Petyon Manning, Tom Brady, and Ben Roethlisberger don't ... muscles ... showing off his All-Pro physique on vacation.

While rumors swirl over Tony Romo taking his job, Alex is down in Hawaii canoeing, and from the look of these pictures, probably not eating much bread.

Joe Mixon just dominated at Oklahoma's pro day -- posting VERY impressive numbers in various drills -- but the question remains ... will an NFL team actually pull the trigger in April?

Obviously, Mixon's past is a huge red flag -- he wasn't invited to the NFL combine because of the video showing him brutalizing a female student in 2014.

Instead, Mixon put his skills on a display at a special workout on the Oklahoma campus -- putting up numbers that would put him in the Top 10 against other RB prospects in almost every category.

Mixon reportedly posted a 4.43 second 40-yard dash time (which would've been the 4th fastest time among running backs at the combine) and completed 21 reps of 225 pounds in the bench press.

Some experts say Mixon will still be drafted as high as the 2nd round ... others say he could fall out of the draft entirely.

Think John Ross' record-breaking 4.22 second 40-yard dash at the NFL combine was impressive??

Well, his speed coach says he coulda gone EVEN FASTER -- claiming he's certain the future NFL wide receiver coulda posted a 4.18 ... had he not cramped at the end of his run.

HE'S NOT KIDDING!!!

TMZ Sports spoke with Gary Cablayan of Evo Sports Training -- who Ross tapped for his pre-NFL speed training -- and he's warning NFL corners ... better ice up.

10 reps on the bench press is bad ... REALLY BAD ... so says Cleveland Browns stud lineman Joe Thomas who says Christian McCaffrey needs to hit the weight room HARD.

We just spoke with Joe about the NFL combine -- and asked the 10-time Pro Bowler if Christian's poor strength showing will affect his draft stock.

"As we all know, there's no bench press on the football field," Thomas said ... "For the most part, your film from every Saturday in the Fall is what should matter."

Thomas also reveals the one question rookies MUST NOT GET WRONG at the combine -- and it's actually pretty hilarious.

Plus, Joe also tells us about BBQ joint, Mission BBQ, and how it's taking over! Who's hungry?

Adrian Peterson is showing NFL teams he's still a FREAK IN THE GYM ... posting footage from a recent workout to prove he's still got the power and explosiveness to dominate in the league.

In the footage, AP knocks out 23 reps on the bench press -- it looks like he's pushing 225 lbs.

Then he grabs the squat bar -- loads it up with another 50 pounds -- and starts doing box jumps!

Peterson added a message -- "Not on a decline, rather an incline! 32 in a few weeks and still schooling!"

"The Biggest Loser" host Bob Harper's looking good following his major heart attack, and says he's taking steps toward recovery ... small ones with his dog.

The fitness guru's been posting pics letting fans know he's getting better, but says the only exercise he's allowed to do right now is walk Karl around the city and in the park.

We broke the story ... Bob suffered the heart attack 2 weeks ago and was unconscious for 2 days and hospitalized for 8.

Normally, he'd be competing in the CrossFit Open this time of year. Strolling with Karl's gonna have to suffice for now.
