Pros Aren’t Trainers, Even When They’re Cute

“Mike and Iworked out togetheronce.

But he pushed them down so hard, my legs just hit the floor.

I was like, ‘I’m smaller than you!

Lighten up!'”

Left: “I love going to live sports events.

It’s fun to have a beer and watch Mike play,” Carrie says.

Her Pre-Event Workout

“I do more cardio and fewer weights than usual.

Although strength training is important, I don’t want to look too muscular on the red carpet.

Now I’m a lot better with saying, I feel good about myself and that’s enough.”

Words of affirmation mean a lot to me.

But my husband is also pretty conservative.

Those shoes were really funky!”

Her Pre-Event Beauty Tip

“Get plenty of waterand sleep.

I’ve heard horror stories about people who’ve done peels or fake tans before events.

What if my face melted off?

I’ll stick to hydration and a little extra night cream.”

“I don’t feel like I have as much to prove,” Underwood says.
