It's a good thing Michael Bisping can multitask ... 'cause the UFC middleweight champ says he'll be training for his next fight against Dan Henderson while shooting his new movie in London.

Bisping locked up a role in the bare-knuckle boxing flick, "My Name Is Lenny" -- which starts filming this week. Bisping says his part will take roughly 2 weeks to complete.

But he also has a huge fight coming up against Hendo at UFC 204 in October -- just 7 weeks away.

So, how will he be able to prep for the fight and shoot the flick?

"My trainer's gonna come with me. I'm still gonna train every day. Film the movie. Come back. Focus on the fight. Kick some ass."

FYI, other fighters like Paige VanZant and Conor McGregor have turned down roles to focus on training camp -- but clearly, Bisping thinks he can handle both.

Swimmer Jimmy Feigen's nearly $11k deal to avoid a Rio jail could backfire against future Team USA Olympians.

TMZ has learned Feigen's $10,800 donation has been tagged to spruce up training facilities for the Reaction Institute in the Rio favela known as City of God. Specifically, we're told the money is going to help fix walls and prevent weather damage to judo equipment.

That equipment is used to give children from the favelas judo training, and put them on the road to becoming Olympians -- who might one day whoop-up on American judo fighters. Brazil's judo gold medalist this year, Rafaela Silva, once trained at the Institute ... so it has a good track record.

As we reported, Feigen struck a deal with prosecutors in Rio ... who agreed to let him off the hook, if he made the donation.

NHL legend Jeremy Roenick says he wants to personally mentor Justin Bieber on the ice -- telling TMZ Sports he GUARANTEES he can take JB's skills to the next level.

Roenick says he saw the new hockey footage Bieber posted online this week -- and was genuinely impressed ... but says the guy has serious room to grow.

"He's pretty tough up top, I don't know about the calves and the thighs though ... it's a little weak."

So, what's the plan?

Jeremy says he'll put together a REAL comprehensive hockey-based workout plan for Bieber -- noting, "I will make you a WAY better hockey player."

David Beckham's 17-year-old son made a fashion statement on the way into a spin class in L.A. Wednesday -- rocking a pink gay pride tank top ... with the socks to match!

Brooklyn Beckham and his world-famous father hit up SoulCycle for a little father/son workout sesh ... followed by a smoothie at the famous Earthbar cafe.

As for the shirt, it's from Palm Springs Gay Pride in 2011 ... so, we're guessing Brooklyn was just going for more of a retro look.

One more thing ... Brooklyn's currently dating Chloe Moretz.

Serena Williams has absolutely NO DAMN SHOT to beat a top men's tennis pro ... that's according to tennis legend Billie Jean King ... who says Williams would go down hard to any of the elite guys.

Billie Jean King is a TITAN in women's sports -- most notably for pummeling Bobby Riggs (who was 55) in a co-ed tennis match dubbed the "Battle Of The Sexes" back in 1973.

We got King out in L.A. recently and wanted to know if the seemingly unbeatable Serena would fair as well against an active men's pro, as King did against Riggs.

Billie's short answer? HELL NO.

King leaves the door open for Serena to do work against guys at the bottom of the male tennis tour, but makes it clear the Federers, Nadals and Djokovics of the world would all smoke her.

Here's supermodel Gigi Hadid ... proving she's one hell of an athlete -- by hitting a heavy bag -- IN HEELS!!!

Hadid hit up Gleason's Gym in Brooklyn -- and despite the fact she was wearing (what appeared to be) leather leggings and chunky heels ... she went all Rocky Balboa anyway -- and looked damn good.

Gigi's been boxing for a while -- and she's picked up a pretty solid overhand right.

#Respect.

Calvin Harris works out like a real-life pro athlete ... so says Minnesota Vikings safety Antone Exum, who says the DJ blew him away during a Thursday gym sesh.

Here's video of Jason Pierre-Paul doing something with 3 fingers that you couldn't possibly do with all five ... pumping a 120 dumbell with the hand he blew up in that fireworks disaster.

It's super impressive ... JPP -- ever in training mode -- breezes through his set like it's nothing, almost making you forget he lost a couple fingers in the accident ... fingers you'd think he needs to lift heavy.

He obviously doesn't ... leading us to our next question.

Arnold Schwarzenegger kept his very physical summer going with a beachside bike ride with one of his sons.

Joseph Baena and dad two-wheeled in Venice, CA after a sesh at Gold's Gym. We also saw 'em pumping iron together a few months ago.

Joseph's all business now in the hair department. He'd chopped his Conan-like flowing locks.

Here's more proof Nick Young only cares about his balls ... he's already re-ignited his hoops training for next year's NBA season, and TMZ Sports has pics of the Lakers star puttin' in work.

Swaggy's fresh off being dumped by Iggy Azalea, and aired out by his baby mama Keonna Green, but it didn't stop him from hitting up the Sports Academy in Thousand Oaks, CA to work on his J.

Check out the pics -- SA is a MASSIVE training center and Nick seems to use every inch of it ... hitting the weights in addition to getting his shots up.

Here's Dez Bryant doing his best Bo Jackson impression ... trying to convince the world he can dominate in 2 sports by taking on some basketball competition in a L.A. pickup game.

Dez hit up L.A. Fitness in Hollywood Thursday ... and hopped on the hoop court with a couple of his homeboys and straight GAVE WORK to the local actors (waiters) in the building.

Sources at the gym tell TMZ Sports Dez's team went on a three game run ... and the All-Pro did his part -- stroking a game-winning 3 from Steph range, which you can see at the end of the clip.

Don't panic, Cowboy fans ... we're told Dez was taking it WAY easy ... just shooting jumpers and not driving into the paint AT ALL.

Kevin Hart's strong.

Check out this footage of the funnyman busting his ass in a Miami gym Sunday morning with Dolphins superstar Ndamukong Suh ... pulling the 320-pounder in a sled LIKE A BOSS!!!

Hart -- who's a hardcore gym rat -- wrote, "Listen up people ... Its not about the size of a man its about the size of the "Hart" within the man!!!! I refuse to be outworked."

He added some pretty hilarious hashtags -- #KickingMyBodiesAss #iPulledTheS***OutOfHisBigAss #ImAbeastDamnIt #BossNeedsToWipeThatDumbassLookOffHisFace #SuhWasGrowlingAtMeWhileIwasPulling."

Sylvester Stallone's training and weight loss show, "Strong" was jacked from the mind of a personal trainer ... according to the suit the guy just filed.

Robert Fletcher says he created a show called "America's Next Great Trainer" and shopped it around Hollywood in 2014. He says he sent his pitch materials to Stallone's publicist, and also to agents at William Morris Endeavor ... which reps Stallone.

Fletcher thinks it's no coincidence that in early 2016 he started hearing about "Strong" -- the NBC show that lists Sly as one of its executive producers.

"Strong" features male and female trainers competing in various physical challenges -- and in his suit, Fletcher says that's almost a carbon copy of his show idea.

He says it's also fishy that one of the "Strong" trainers is a guy named Todd Durkin. Fletcher says Durkin was attached to 'ANGT' ... but went radio silent in 2015.

He's suing Stallone, NBC, Durkin and other "Strong" producers for at least $7 mil.

Well, now we know what the J in J.K. Simmons stands for -- JACKED.

Check out the 61-year-old beasting out in an L.A. gym -- gearing up for his role in the upcoming 'Justice League' movie.

No, he's not playing Bane ... or Batman ... he's an insanely muscle-bound Commissioner Gordon!

Simmons has been training with retired Marine Aaron Williamson -- who reportedly got Zac Efron into shape ... and who's been known to push weights with The Rock.

SoulCycle's crappy instructors and faulty bikes are to blame for a catastrophic ankle injury ... so claims a very disgruntled customer.

Carmen Farias claims in a new lawsuit she showed up to spin class in 2014 and, since she was a newbie, she expected someone would show her how to use the bikes. Farias says she started riding but quickly tired and the instructor barked, "We don't take breaks."

Farias says she was so embarrassed she soldiered on, as her feet were locked to the pedals. She says she became so fatigued she fell off the bike with her feet still strapped in ... but the momentum of the fly wheel kept the pedals turning, and each rotation caused ankle dislocation.

She blames the bikes and lack of instruction for what she claims are catastrophic ankle injuries.

Chicks are still into Warren Sapp ... well, at least one is ... 'cause the NFL Hall of Famer just got himself a new GF, one year after he beat up his last one.

Sapp just posted a pic of himself with his mystery lady -- along with the caption, "Couples that work out together ... "

No word on the identity of Sapp's new lady -- but it's pretty clear it's NOT the same woman he brutally attacked in Vegas last year (the old GF is black, new GF appears to be white).

As we previously reported, Sapp pled guilty to 1 count of domestic violence -- after his longtime girlfriend claimed Sapp bit her and stomped on her head during a fight that began at a Vegas hotel pool.

And just a few months before that, Sapp was arrested in Arizona for a violent incident involving 2 prostitutes.

But Sapp's off probation in both cases and essentially has a clean slate.
