Work out with me

Hey there, I’m Cath!

I’m a personal trainer and owner of In House Studio Fitness in Mulgrave, Victoria. My mission? To create a welcoming, inclusive space where people of all fitness levels can feel supported, challenged, and most importantly—have a great time while working towards their goals. We sweat, we laugh, and we celebrate every win together.

Beyond the studio, I also run an online training community where you can join me for fun, effective home workouts—no matter where you are.

When I’m not helping clients get stronger and feel amazing, you’ll probably find me traveling the globe with my wife, Deb. From Sweden and Finland to Greece, Italy, Vietnam, Indonesia, and even the North Pole—life’s all about experiences, and sharing them with Deb and our friends is my greatest joy.

I’m also a die-hard AFL fan (go Tigers!) and never miss a game—whether I’m in the stands or glued to the TV.

Closer to home, I’m kept busy by my gorgeous Westie, Georgie, who insists on daily walks and playtime. Between her, my wonderful family, and incredible friends, my days are filled with love, laughter, and purpose.
