I’m comfortable in that!”

This ability to handle whatever comes her way also inspired Hudson’s latest leapbecoming an author.

“Why not put it out there?”

Consider us ready and listening.

Here, Hudson shares 10 principles for radiating positive energy inside and out.

“Change is my constant.”

“I change my routine.

I change my look.

I change my mind,” says Hudson.

And when it comes to exercise, she says, “I really switch it up.”

Her only fitness regimen, it turns out, is not having one.

“I’ll doTracy Anderson, I’ll doBody by Simone, I do everything,” Hudson says.

Her other love isexercising outdoors.

While outside, she says, “your body is constantly adapting as it moves.”

Still, when she really wants to whip herself into shape, she focuses onpilates.

“I’ll travel, and I’ll go for a run or I’ll Spin.

But when I go home and get on the reformer or the Cadillac, my body immediately goes back.

I can see an instant shift.”

She typically works out in the mornings after her kids are dropped off at school.

But she’ll still make time to fit in a mini-workout on the fly.

“When people talk about dieting, I’m just like, OMG, relax.”

As with exercise, Hudson ismindfulbut not obsessiveabout what she eats.

She goes for five small meals a day, sticking to unprocessed and plant-based foods for the most part.

“I’ve pretty much cut meat out,” she says.

“I don’t remember the last time I ate a steak.”

The challenge, she says, has been changing her a.m. routine.

I’m not one of those people who wakes up hungry," she explains.

“I like living my lifeI’m not highly regimented.”

Hudson isn’t averse to guilty pleasuresin fact, she encourages them.

“I want toindulge!

I want to do things that are not necessarily healthy sometimes.”

Hudson tells the story of a close friend who struggled for years with being overweight.

“One day her thinking shifted.

And she said, ‘You know what?

And the weight started coming off.

I really do believe it starts in your head,” Hudson says.

“Dancing can be a great release.”

When it comes to letting go of stress, Hudson has an instant happiness trick.

“Dancingis the thing for me,” she says.

“It just makes me feel so much better.

You know how you see dancers always crying?

It’s like reconnecting with an old self.”

“Sometimes I’ll lock myself in a room and dance.

I’ll turn music on as loud as possible and just get weird!”

she says, laughing.

“I don’t judge my practice, ever.”

To stay fit and mentally sharp, Hudson believes in using whatever techniques work for you.

“It’s about understanding your own individual likes, not fads,” she says.

For Hudson, that means doing transcendentalmeditationand Kundalini, a form of brain-focusing yoga.

“That’s what my book’s aboutdon’t beat yourself up,” she says.

“Journaling keeps me centered.”

“What are you eating?

What are your food patterns?

it’s possible for you to get clued in to the things that are going on with you.”

“Find the place where you feel really good in yourself.”

Forget the trolls and shamers.

And that’s not our fault.

That’s what culture and society have gifted us as women," she says.

“Thank you but no thank you.”

“Exercise is a way to connect with people.”

Being part of a wellness-minded community is major#Fitspofor Hudson.

“Every time I’m on an airplane, girls are like, ‘So!

Here’s what we think you should make,'” says Hudson.

“It becomes a dialogue.

I love it.”

“Your mental health is so key to your physical health.”

You’ll never look or feel your best if you’re emotionally run-down.

Having access to her family and a tight-knit group of girlfriends keeps Hudson on an even keel.

That includes her former fiance, Matthew Bellamy, with whom she has remained friends.

“I don’t take myself too seriously.

That’s how I am.”

“I think finding the balance really is more about emotional balance, isn’t it?”

“Sometimesstresscan be good stress.

The whole point is that life doesn’t ever get easy.

And so you have to learn how to enjoy it.”
