I like the bicep curl / overhead press combo that she did there.

I don't smile when I work out

From all the pics I've seen of her, she doesn't look very fit at all.

I think she looks fit. Not buff or muscular, but fit. She's still really young and her body is still growing.
And I do smile when I'm working out. I loev working out with my trainer, we joke and laugh and have a good time while he kicks my butt. I like seeing celebs actually working out for thei bodies instead of hearing people say they're eat whatever they want and never work out. I hate that.

I think she looks fit too, but, she still looks like she doesn't work out nearly as much as it shows she does here. That's also because she's still growing into herself at her age.

I'm so happy that I stay active enough in my personal life so I don't have to work out a ton and kill myself at the gym.

good for her and i imagine she wasnt going full out while she is being interviewed..but i feel her on sometimes needed the trainer..i used to have one and he was a big help

DARN!!!! I can't see the video here at work..POOP! >=/

I saw this morning she is signing deal with portionpals.

I just love this girl! I always thought she looked fit...this is how she does it! I like how she has a body that is reasonable for young girls to want to match. She isn't too thin.

I love her on Heroes but hearing her talk in real life and being herself...I just don't get what a 30 year old sees in her. She's still VERY childlike.

"I don't even know how much I weigh anymore." Doubtful. But even if she doesn't, that little quip definitely did not need to be in the video. It was supposed to be about her being fit anyway, so I think it should have been left out. Anyway, I found her kind of annoying in that video, but I'm sure people would find me annoying if I did a work out clip too, so I guess I shouldn't judge!

Um, she looks pretty darn fit to me! That does look like a good workout. I'm going to add a couple of those moves to my own workout!

I adore her.

Who wears makeup to the gym!

Desk jobs suck. I get so bored and when I get bored I eat. I'm still relatively thin beacause I'm pretty lean but I have started gaining. I definately push myself to get in the gym right after work before going home. Its great to see a celeb (even though I don't really know why she's famous) getting fit. Sometimes I look at pics of my fav Victoria Secret models or Jessica Biel before I go to the gym, so I remember why I need to keep going.

Well it was obviously some sort of photo op. Still, at least 80% of all the pap photos of her are going back and forth to the gym. I think she has quite a classically athletic body. She looks healthy and not too skinny to me, but it's nice that she doesn't just go "Seriously, I NEVER work out, I love eating junk food!" like most actresses seem to feel they have to say.

isn't she like 18? I would certainly hope she would look young and fit! you shouldn't have to do a thing at that age unless you are already overweight.

I like that she works out and is fit, a good rolemodel for all the young girls out there. Better than the stick thin models who looks like they eat 5 grapes a day.

She is *teeny* in real life! I met her last summer at TCA, and she's even smaller than I expected her to be.

She's adorable.
What brand is the bra she's wearing under her tank?

I'm with Laura, I always thought she didn't exercise that much because she looks 'normal' and not buff - guess her body is still very young.
BTW it's the first time I hear her speak (I don't watch Heroes so I'd always seen pictures), she does sound very young!

Haha Buzz, I'm even smaller than her, don't know what you guys would say about me!

Im still creeped out that dating a 30 year old man!

Anyway, she only 18, when I was 18 I was about 100lbs - I never worked out unless u count PE class a workout, shes still growing.

Now Jessica Biel and Beyonce. Their bodies are flawless.

I think it's so nice to see someone considered "Young Hollywood" actually being healthy and not super skinny or partying non-stop. She's such a cutie and a good role model for younger girls.

She's healthy-looking and of average build, I'd say...never really thought of her as super-fit or anything.

I think she looks amazing! I thought it was funny how she mentioned the wide screen tv's making her look bigger.

Haha, Advah! I was mostly surprised at how petite she was overall — I always expect stars to be really tall, for whatever reason.

To be honest being that in shape at her age is perfect. People should start working out at a young age like that because then it becomes part of a lifestyle.
Good for Hayden and showing girls an attainable body shape.

And I think that she looks to be in excellent shape. Everyone's body reacts to exercise differently so some people look more tone than others. And then there's the people who do nothing but appear to have athletic physiques... these are the one's we're all jealous of.
I have a degree in Kinesiology and I've seen people who you would not expect to be in shape whip my ass at the gym.

I think she's in great shape! She is wearing make-up to the gym because she is on camera and is constantly photographed going to and from the gym. I hate women who wear makeup to the gym, but honestly, if I were photographed I would definitely wear it, not like it's a ton anyway. I like her, I know she is kind of perky, but she seems pretty cool and healthy. It really seems like she has a healthy balance of working, staying healthy and going out for an 18 yo. Not sure about the 30yo bf, but...whatever, she can't be perfect.

And I used the word healthy about 100 times...this is why they chose Hayden for this ad/whatever the heck it is!

I wish I had the motivation (ahem...$$$) to exercise as much as she does at her age. I'm only 5 years older, but I really should've been on it. Childlike or not, Its good that she wants to be healthy!

i like that she works out..but come on she had a make-up artist or someone dabbing her face..i feel like ive really worked out when i sweat! but thats just me

I love her!i'm lucky, i'm naturally skinny so i don't have to work out that much, only when its bikini season and i need my abs.

i don't like her..i think she's fake and tries too hard!!
