Kelsea Ballerini doesn't want exercise to "feel like a punishment"

She told People magazine about her fitness routine: "For me, it's walks. Walking is so good for you. It also makes you get fresh air and some good sunshine, and that's so good for your mental health.

"I'm a Pilates girly. That for me has been my tried and true the last five years because I don't hate doing it, and I don't want working out to feel like a punishment."

When it comes to her diet, Kelsea follows an "80/20 rule".

She explained: "So 80% of the time I'm really healthy, 20 per cent of the time catch me at McDonald's.

"My favourite thing to cook - I've been upping my protein a lot recently just because I didn't realise how much protein we're supposed to have as women- and I cook a really good chimichurri steak ... that is my go-to.

"I'll do it a couple of times a week. I have some in the fridge downstairs ready to go."

The Cowboys Cry Too singer loves an occasional treat meal from McDonalds, which she believes is a throwback to her childhood.

She said: "As a kid, I was such a picky eater, and my parents joke with me, like, 'All you would eat were waffles and chicken nuggets.' So I think it's just probably my inner child craving it still."

As she gets older, Kelsea's attitude to fitness has changed with her desire to be "360 healthy".

She said: "I think especially in my early twenties and mid-twenties, the idea of fitness was very much only aesthetically driven, and that was my goal.

"The older I've gotten, [the more] mentally healthier I've gotten as well...

"I want to be mentally healthy. I want to be physically healthy, emotionally healthy, and I want to be able to sustain the life and the career that I've been lucky enough to build for myself...

"It's the most important thing to me now, honestly."
