I’m Katrina Scott. I'm a fitness founder, a mama, a podcast host, and your brand-building-business-bestie. Thanks for stopping by!

Branding and Community Building Expert
Body Kindness Advocate 
Co-Founder of Tone It Up
NY Times Bestselling Author

I was born and raised in New Hampshire, but you can find me in Southern California on the beach. I’m a lover of all things decor, booty workouts, beauty, and branding. When I’m not chasing my toddler around the house, I’m teaching fitness classes on the Tone It Up App, browsing Pinterest, or re-decorating a corner of our house… again.

Things that make my heart happy are… my daughter, helping girlfriends achieve their dreams, family dinners on Sundays, and sipping an Aperol spritz while listening to ‘Girl From Ipanema’ on a boat with my cocktail captain, Brian.

At 18, I taught female-focused workout classes on campus *cue Rhianna SOS. After graduating with a degree in Health Science and Fitness, I began my career in Boston as a Master Trainer and Group Fitness Instructor. I quickly started filming workout videos as the first Fitness Expert on YouTube. Bringing a fresh and bright perspective on health and wellness, I reached over 17 million viewers in the first two years.

With just a tripod, a camera that Brian gave me for Christmas, and big dreams, I moved to California to pursue my goal of filming fitness videos on the beach and creating a powerful fitness brand for women, Tone It Up! We made Manhattan Beach our home and that's where I met my co-founder, Karena Dawn. Together, we created a global fitness community for women, the leading fitness app, Studio Tone It Up, and clean, plant-based nutrition products that are available in every Target nationwide.

10 Things

Named after her two grandmothers, Isabelle Margaret has stolen our hearts! We waited a long time to have her and we’re incredibly grateful.

Isabella's Mama

I met my husband Brian in New Hampshire when I was just 19! We dated for 10 years making it through college, long distance, and moving across the country together. We got married in 2013 and had our daughter Isabelle on 10.15.18.

Wife for Life

Growing up, I was teased for being overweight. I asked my dad for a treadmill... instead, he empowered me with a home gym equipped with fitness books, barbells, weights, a bench, and of course the treadmill I asked for… I was in the 5th grade! I fell in love with fitness and went to college for Health Science to help other women transform their lives. 

Science Geek

I grew up watching my Mom run her own interior design and clothing alteration business. It was fun, because I would sketch a design of a prom dress, palazzo pants,  or a bikini, and she would make them for me! Now, I love DIY design and decor… give me some fabric, dried flowers, a glue gun, and some chalk paint, and it is ON. Now I just need to learn how to sew...

DIY Lover





I LOVE beauty… but it’s safe to say I don’t have much time dedicated to it. I’ve had the honor of doing all my friend’s hair and makeup for as long as I remember. From proms, to date nights, their weddings, photoshoots, and special events (even Coachella fueled with champagne)… I just love making my friends feel beautiful. These days I just quickly brush bronzer on before running out of the house with Bella! 

Secret Beauty Guru

I wish I could live so many lives… next round, I’ll follow my mom’s footsteps in design. I love decor, creating tablescapes *thanksgiving is my jam *, flee market dates to discover vintage finds, decorating girlfriend’s places, and creating beautiful spaces. 

Wannabe Interior Decorator


I grew up painting. I’m no pro, but I love it!  My grandmother Isobel was a painter and we have her paintings all throughout our home.   She inspired me to pick up my first brush when  I was just 6 and I hope to follow in her   footsteps one day. Should I bring back these bangs too?


you're gorgeous!




You can workout with me along with the most incredible trainers in Studio Tone It Up! I love barre with Tori, HIIT with Ari, boxing with Chyna, meditation with Karena, running with Stef, cycling with Kristina, yoga with Chevy, weights with Yami, and of course, I love creating strength and sculpt workouts for you! I'm grateful for this journey with our #TIUfamily. See you in there every day!  

Fitness Trainer

My big brother Stephen is my best friend and biggest supporter! We now live down the street from one another and our babies are BFFs too.  I love our beach days, family dinners, lake trips, and I always feel safe and secure knowing my big brother is by my side.

Little Sister

Home is where the heart is! My family is back east and we spend our summers on Lake Winnipesaukee in New Hampshire. Growing up, I went to Camp Nokomis where I learned how to sail, play tennis, swim, and keep raccoons out of a cabin, because I smuggled in M&Ms and cookies... true story that I'll share some day on the podcast.

I can't wait to be back on the lake this summer with family. * m&ms + wine included * 

Lake Girl





My favorite foods are chocolate and ice cream… but I don't like chocolate ice cream. 


I grew up curling and I was on a traveling league... yes, that funny sport on ice.
I cherish photos… but still haven’t made our wedding album. 
I live on the beach… but I’m really a lake girl at heart.
One of my favorite things to do is make flower arrangements... but I can't keep flowers alive.
Writing is a passion, but I'm dyslexic, so it's also a struggle.
