"My boyfriend’s healthiness inspires me," she told Good Housekeeping for this month's issue. "Aaron is different than every other man I’ve ever met … there’s so much I could say."
She continued, "Everything a good person can be, he is. He’s in such great shape, and especially lately, he’s been eating so well and working out. Having somebody in your life like that is so motivating.”
Working out is also something that helped the former "Newsroom" star with her OCD.
Now, if Munn even misses one workout, she'll "double up and do it the next day."
"Now I feel so much stronger. I remember running up the steps one day and thinking, 'This is strange. I could do this a hundred times and be totally OK,'" she said.
Munn also opened up about parenting a little puppy Chance with Rodgers.
"I wasn’t looking for a dog at all, and then I saw this little guy and was like, ‘I have to have him,’" she said. "[Chance’s good behavior] around Aaron is a direct reflection of how Aaron has been training him — how much respect Aaron has for Chance, and how much respect Chance has for him. I’m like ‘You’re my baby. You can do whatever you want!’ I realize now how important it is for me to be a good parent to him, because it’s a direct reflection of me. Chance made us a family … he and Aaron have changed my life in every way. My world has become so much brighter, sweeter and lovelier. I feel grounded with them in my life.”
