Stacy Keibler's healthy and amazing body has blown minds around the world, each of us wondering just how they hell she does it! Everyone has their secret, so what's hers??
Her secret happens to be a piece of equipment IN ADDITION to staying focused on her diet and her workout schedule! That piece of equipment is the Cybex Arc Trainer, and we have proof that she loves to sweat all over it!
We TOTALLY love watching her do it! Ha!
Ch-ch-check out the rest of the pics (below) for a look at her secret weapon in the battle against flab! LOLz!
We're a little bummed there isn't a photobomb in these, but they can't all be winners!

Pumping iron never looked so damn sexy!!
With bikini season officially upon us, tons of celebs are hitting the gym extra hard to keep their tightly toned bods in tip top shape!
But for this lovely lady, it's ALWAYS bikini season considering she's an international supermodel and it's pretty much her job to make us sweat!
This particular German beauty took to Twitter to share a pic of herself saying "auf Wiedersehen" to some extra pounds and looked pretty dayum good while doing it!
So which super fine mama is putting the rest of the boys and girls to shame with her stunning figure??
Yup! You guessed it! The bangin' bod belongs to one mother we'd like to cuddle …AFTER THE JUMP!!!

Pregnancy fitness is SO important, as long as you're not straining yourself!
A little light yoga, some walking, or some pregnancy pilates will go a long way to keeping you and that little one healthy! That's why we're so glad to see that Jaime King isn't shy about hitting the gym with her bump!
Today she was spotted heading to Pilates (above and below)!
We're also happy to see she has a healthy smoothie for energy — she IS hydrating and taking in nutrients for two now!
We just wonder if they added an extra shot of prenatal vitamins for her! LOLz!

Kimberly Stewart is at the gym SO often we're starting to think she lives there!!
Ok, so that's most likely not true, but you get the point!
Rod Stewart's sexy daughter was once again spotted leaving her gym in Los Angeles, and it DEFINITELY looks like all of the extra hours of sweating are working out for her!
Despite her fab looks, we couldn't help but notice Kimberly looked a little down in the dumps as she headed home for the day!
Did someone steal her favorite workout machine? Did she spill her Gatorade? Or was she just listening to a super sad Taylor Swift song while getting her jog on??
Whatever the reason, Kimberly has NO reason to be upset, because as usual she looks FANTASTIC! Seriously, check out those Hot Legs!!

You know what they say: The early bird gets dibs on all of the workout machines!
Wait, that doesn't sound right…
Anywho, Reese Witherspoon got a VERY early start on her day and was spotting heading over to Kinetic Cycling in Brentwood for a morning workout!
Looks like she must've set her alarm for the butt-crack of dawn! LOLz!
We gotta give major props to Reese for finding the energy to workout so early in the morning, because we probably would have hit the snooze button a few times if we were in her shoes!! Ha!
But hey, who needs coffee when you can break a sweat instead!

Two tickets to the gun show, please!!!
Colin Farrell got our blood pumping once again as he was spotted showing off his muscles and tattoos after a nice workout in Los Angeles!
Unfortunately, he was a little more clothed than we would prefer, but we STILL love seeing him all hot and bothered!
We're huge fans of any movie where we can get our fix of Colin eye-candy, and we're loving the new role he's taken on of sexy, sweaty gym rat! LOLz!

There are two things that are guaranteed to get your heart pumping: Hitting the gym for a nice workout, or staring longingly at Jordana Brewster!
We'll go with the second option!
The Brazilian beauty, on the other hand, went with the healthier choice as she was spotted leaving her gym in West Hollywood after pumping some iron!
Jordana had her hands full as she headed home for the day carrying some Vitamin Water, her iPod, and a tote bag we can only assume is filled with all of the hearts she broke at the gym! LOLz!
Sorry fellas, she's taken!!
