Fitness & Exercise

Rob Kardashian is showing glimmers of a toned body, judging from what looks like some pretty muscular calves.

Rob arrived at LAX Monday and his body was almost entirely shrouded in workout gear, but there are certainly signs he's dumping the weight faster than his sister 86'd Kris Humphries.

Lookin' good.

Ted Cruz has turned his "breathe" jab at Donald Trump from last week's GOP debate into a cash cow by slapping it onto a yoga mat ... and the demand is off the charts.

We got Cruz outside of Dulles airport, ticking off the benefits of the portable American-made mat he recently listed for sale on his website.

Truth is, the thing sells itself. The first lot hasn't shipped yet, but it's already on back order.

Still, if you needed any more convincing, Cruz gives a hard sell.

The gym staffer who called 911 on Kam Chancellor said the Seahawks player was "bad news" -- and had been "pounding" on the doors ... even though the gym was closed.

TMZ Sports obtained the 911 call ... in which the woman at the Redmond Athletic Club in Washington describes 5 people (3 black and 2 white) who came to the gym unannounced.

The woman said she explained that the gym was closed, but the group refused to go -- "They're trying to get in and we've told them multiple times they need to leave."

At one point, the woman says, "I don't know if they're homeless kids ... I know there used to be a lot of heroin addicts around here."

Eventually, cops came to the scene and spoke with Chancellor -- who explained his side of the story. No arrests were made and cops say Kam was a "super nice guy."

The owner of the Washington gym Kam Chancellor was scouting out Wednesday night tells TMZ Sports he has reached out to the Seahawks star to explain why his employees called police on him ... and says he still wants to make a deal.

If you haven't heard ... Chancellor says he was scouting the Redmond Athletic Club last night because he was interested in buying the place -- and went to the building with friends to check it out.

Problem was ... the gym was not open and staffers inside called police because they were concerned.

Kam tweeted, "They told the cops I was trying to rob the place because I was looking into the glass asking for help."

Many people believe the call to cops may have been racially motivated because Kam is black.

But we spoke with the owner of the gym, Ryan Neal, who tells us, "We have reviewed the situation and can assure you that race was not an issue here."

Neal says the gym has recently had attemped break-ins and the staff was told to call cops if it appeared anyone was trying to gain access to the gym while it was closed.

Neal says he has reached out to Chancellor -- and says he would love to talk business if Kam is still interested in buying the gym.

Finally, hard evidence GB Packers running back Eddie Lacy took up the offer to train with P90X creator Tony Horton -- and we gotta say ... the dude looks like he's already getting results.

Check out the photo Tony's training pal Bobby Stephenson posted on Facebook -- showing Eddie and Tony after a workout with the caption, "Crushing Shoulders and Arms P90X Style."

Packers coach Mike McCarthy had said he wanted Lacy to shed some serious LBs before next season -- and that's when Horton volunteered his services.

Check out what Lacy looked like 31 weeks ago ... looks like Lacy is taking the workout plan very very seriously.

Mark Zuckerberg went for a casual jog Wednesday afternoon in Berlin ... with at least 5 dudes in stride to watch his back, front, and sides at all times.

The Facebook billionaire -- who pledged to run 365 miles in 2016 -- was recently the target of threats from ISIS, so you can understand the large entourage. Despite the tight coverage, Zuck's guys are not actual bodyguards, just FB execs traveling with him.

Blac Chyna's pissed she's looking like the bad guy after posting a vid of all the food that was stocked in Rob Kardashian's kitchen ... when all she's doing is helping him slim down.

We're told she's upset because people think she was insulting Kris Jenner, who was presumably behind the quinoa, gourmet crackers, I Can't Believe It's Not Butter ... and other healthy items purchased. Remember, he's diabetic.

Sources close to Rob and Chyna tell us they have a strict no carb rule which has been instrumental in helping Rob shed lbs. We're told Chyna was just busting on the carb-filled selections in the cabinet -- and has zero beef with Rob's mom.

Besides, we're told Chyna doesn't even buy that Kris picked out the food. As one source put it, "When's the last time you saw Kris Jenner inside a grocery store?"

Jennifer Lopez sweaty with no makeup after a cardio workout still looks hotter than most people do on a Friday night out.

J Lo's twins Max and Emme turned 8 on Monday so she was likely burning off the birthday cake or just firming up her best asset.

Her abs are definitely giving her ass a run for the money.

Rob Kardashian is sticking to a strict diet -- no fast food, regular workouts and lots of Blac Chyna ... and friends think it's already helped him shed about 40 lbs.

We're told Rob's also cut out red meats and carbs while hitting the gym 5 times a week with a trainer ... plus additional workouts with Chyna.

We're told the couple made a "no cheat days" vow, and they're motivating each other to stick to it.

It's hard to say the program isn't working, based on recent pics. Some home cookin' from Blac Chyna doesn't hurt either ...

Eddie Lacy could be coming back to Green Bay straight DIESEL ... 'cause it looks like the Pro Bowler has taken up P90x creator Tony Horton's offer to train him ... we think.

We broke the story ... Horton made an on-camera plea to Lacy -- basically begging to train the running back -- after Packers head coach Mike McCarthy demanded Lacy drop 30 pounds before next season.

Well, there is some evidence to suggest the two have linked up and are getting it RIGHT NOW in Jackson Hole, Wyoming ... namely a tell tale Moose.

Check out these two posts that each guy put up on social media recently -- pay attention to the certain alces (look it up) figure that shows up in each shot.

Need more? How about GB head coach Mike McCarthy saying Lacy is "conditioning as we speak" in a presser he just gave ... seemingly aware of Eddie's efforts to shave some muffin top.

Kylie Jenner is a spokesperson for the direct rival of Kanye West ... PUMA.

It's a stunning development ... because remember, just a week ago Kanye tweeted, "1000% there will never be a Kylie PUMA anything."

We're told Kylie will be in the Spring/Summer women's training campaign, which launches in April.

PUMA says Kylie represents, "a fresh and exciting new era for fashion and we couldn't think of a more fitting and influential female to headline this campaign."

Remember, Kanye called out PUMA, telling them, "PUMA, we gone give you your measley million dollars back!!! Never try to divide the family!!!"

Family divided.

If Tiger Woods wasn't kickin' himself before ...

Here's Olympic skiiing legend Lindsey Vonn getting in a quick workout while on the set of her Sports Illustrated Swimsuit Edition body paint shoot ... and it's awesome.

Not only is she basically naked -- and beasting out with a set of full grown-ass woman pull-ups -- but she's also doing it while sporting a pair of high heels.

Here's LSU running back Leonard Fournette busting out a set of 405 POUND squats like it's nothing.

Last year, Leonard said he could max out at 605 lbs ... and the way he knocks out 405, it makes you wonder if that number has gone up even more.

For comparison, here's Alabama running back Derrick Henry busting out 1 rep of 500 pounds last year.

Lamar Odom is doing so well, if you didn't know he was at death's door in October, you would never know he suffered 12 strokes and was unable to walk or speak.

As we reported, Lamar went hiking with Kim and Khloe over the weekend. The doctors never thought they would see the day. But even more surprising ... Lamar's cognitive functions have significantly returned ... he's able to process thoughts, speak them and carry on conversations.

Lamar had significant problems recognizing people -- even family members -- for several months after he was rushed to the hospital. But now his recall is back.

We're told Lamar's not completely back. He's still "a bit slow," and has memory lapses and sometimes has problems speaking. But the issues are subtle.

As for the hike, we're told his goal is to be able to run again. He's not there, but he's determined and believes he still has a shot at playing basketball again.

We're told Lamar's trajectory is so miraculous, he has a shot at living independently in a matter of months.

Looks like it's chest day for Rob Kardashian.

His chick, Blac Chyna, documented his bench press reps -- although she conveniently kept the bar and the weights out of frame.

We don't know how much Rob's lifting, but we can say his arms are looking fit.

If Eddie Lacy is on the fence about training with the P90X guy ... this could be the video that pushes him into the "yes" camp.

We ran into Troy Aikman in NYC -- and since he's a huge fitness enthusiast (not to mention an NFL Hall of Famer) ... we asked if P90X could actually do the trick for Lacy, who's been under fire for being overweight.

Long story short -- Aikman approves in a big way.

And in case you forgot ... Troy is pretty shredded.
