Celebrities With The Sexiest Six-Packs!

These hot, muscled hunks prove that they’ve got the most amazing abs in Hollywood

1. David Beckham

David struts his stuff in his tightie-whities

David Beckham isn’t at all shy about showing off his chiseled physique, whether he’s ripping off his shirt on the field post-goal or baring almost everything in revealing Emporio Armani underwear ads. “I just like using free weights and doing abdominals,” says the husband of Victoria “Posh” and father of three boys, on how he keeps his taut tummy. Still, there’s one fan who isn’t so thrilled about his exposure in nothing but skimpy briefs — his mom! “When the photos came out, she was the first to call me,” David, 33, says. “I had to try to explain it to her, and it didn’t go down that well.” Victoria says that the secret behind her husband’s fine form is that “he’s really healthy.” Giorgio Armani says he handpicked Becks as a model because “his body brings to mind the beautiful Michelangelo statue in Florence.”

2. Robert Buckley

Robert knows he has to look good for TV

“I was on the chubby side and used to swim with my T-shirt on,” admits Robert Buckley, now 27, of his childhood. It’s ironic, because as Lipstick Jungle’s resident piece of man candy, he rarely wears a shirt — or much of anything else — on-screen. “Staying in shape is all about keeping yourself motivated,” the actor, who is an avid runner, tells In Touch. “And personally, I’ve found that there’s no better motivation than knowing I’m going to be practically naked in front of millions of strangers every week.” “People say to me, ‘You’re the guy who’s naked all the time,’” says Robert.

3. Mario Lopez

Mario’s always on the go

“I’m very flattered,” Mario Lopez says about making the list, before revealing his secrets for maintaining washboard abs. “Try to break a sweat every day,” he tells In Touch. “Make time to work out, even if it’s just for 10 minutes. Try to eat every two hours, and always change up your workout routine to keep your body guessing.” To do that, the 34-year-old Extra host and author of Mario Lopez’s Knockout Fitness does everything from boxing to cycling to dancing. “I like the way it makes me feel,” he says of working out. “The way my body looks is a by-product!” “I really got into exercise when I was a teenager — dancing, running, wrestling and boxing,” Mario says.

4. Hugh Jackman

Hugh trains like a wild man

Hugh Jackman has been tall and lean his entire life, but it wasn’t until he was cast in X-Men that his six-pack really took shape. “For Wolverine, I ramp it up,” says the 6'2" hunk about his intense workouts for the popular film series. “I train really hard. I crank up the Godsmack and Metallica. I yell and scream, which helps me have a bitch of a workout,” notes the dad of two, who also cuts bread and most sugars from his diet to help trim the fat. And he’s happy to show off the results. “I’m not shy,” Hugh, 39, says. “I’ll peel off my shirt if the script requires it.” “Call me a slut, but I thought it was fun,” says a confident Hugh of the full-frontal nude scene he shot for X2: X-Men United.

5. Shemar Moore

Shemar admits he’s a total gym rat

Shemar Moore is such a workout fiend, his bosses at Criminal Minds got him his very own gym on wheels. “I have a workout trailer that travels with us from set to set,” says the actor, 38, who relies on a trainer to push his body to the limit. “I lift weights four days a week for an hour and a half each day. I box three days a week for an hour a day. And I run four miles a day, four days a week,” says the diehard jock. “I’m not gonna lie. I’m vain, like anybody else,” he adds. “I need that adrenaline rush. It just makes me feel good.” “I’ve worked out my entire life,” says Shemar. “I’m not right if I don’t work out.”

6. Ryan Sutter

Ryan is a natural born athlete

“Wow, that’s quite an honor!” says Ryan Sutter of being named to In Touch’s Sexiest Six-Packs list. “I just do things I enjoy, and they just so happen to be good exercise, so it takes that whole ‘I have to go work out’ thing away,” the husband of Bachelorette Trista Rehn and dad to 13-month-old Maxwell says. The former college and pro-football player likes to run, swim, snowboard and mountain bike, and he’s even competed in the grueling Ironman World Championship. “I barely even do sit-ups, to be honest,” the 33-year-old reveals, opting instead for “a lot of balance-ball stuff and core-strength exercises.” “I have an almost ritualistic breakfast routine,” says Ryan, who likes to start the day with yerba mate tea and granola with acai fruit and hempseed oil.

7. Gavin Rossdale

Gavin hits the courts

“That whole mouse-on-a-wheel thing, day in and day out, gets monotonous,” says Gavin Rossdale, hubby to pregnant Gwen Stefani and father to 2-year-old Kingston. He’d much rather work on his tennis game than run on a treadmill. To get his abs of steel, the 42-year-old rocker warms up by jumping rope, then adds bursts of cardio while he practices his swing. And since he plays with opponents of varying styles and on different surfaces, his muscles are always challenged. “All of these destabilizing factors make me a better player,” says Gavin — and they keep him looking ripped! “I love tennis. It’s like being a modern-day gladiator,” says Gavin.

8. Brody Jenner

Brody doesn’t want to look too buff

Brody Jenner spends as much time working out as he does going out. But considering his dad, decathlete Bruce Jenner, is an Olympic gold medalist, it’s clear that staying fit is in the 25-year-old’s genes. “A lot of times I’m traveling, so I don’t get to work out every day,” he admits. When the Hills hottie isn’t sweating through grueling workouts in the sand, he’s hitting the bags during boxing lessons with a personal trainer on the roof of his condo. But Brody isn’t looking to bulk up. “I’ll run, but I don’t do a lot of lifting,” he says. “I used to surf every day,” says the former Malibu resident. “But now that I live in Hollywood, it’s a pain to drive there to surf.”

9. Zac Efron

Zac works out like a true champ

His High School Musical character is a basketball jock, but Zac Efron didn’t get those abs just from shooting hoops. The self-described exercise junkie was actually inspired by another fictional sports star. “After watching the entire Rocky series, I got hooked on fitness,” says the 20-year-old, who hits the gym five days a week. “It’s so important — you feel incredible. Working out is my biggest hobby. It’s my Zen hour. I just zone out.” “I like to stay active. If it gets me outside and gets me moving, then I love doing it,” says Zac.

10. Matthew McConaughey

Matthew has fun in the sun

Matthew McConaughey swears he enjoys every sweat-soaked second of his exercise regimen. “I just feel better when I work out,” insists the 38-year-old first-time dad, who got himself a tiny new workout buddy when girlfriend Camila Alves gave birth to their son, Levi, on July 7. “I do sit-ups, push-ups and jogging. Whether it’s going for a run, dancing or loving, my rule is break one sweat a day,” he says. And though Matthew loves nothing more than to take his workouts outdoors, even bad weather can’t slow him down. “When it’s raining, shadowbox for 20 minutes,” he says. “Go hard and I guarantee you’ll drip a sweat, man.” “It’s fun to feel healthy, and it’s Matthew says. “And I gotta have both.”
