Fitness that's actually fun — and a first week that's free.
Friendly small-group sessions with Cath Grech, where no two workouts are ever the same and everyone belongs — whatever your age, shape or starting point. No judgement, no intimidation. Just good people, real results and a few laughs along the way.

A fitness experience like no other
From early-bird starts to evening energy-burners, every session blends strength, cardio, core, balance and stretching into something genuinely enjoyable. You'll never watch the clock — and you'll never get bored.
Small groups
Train in a small, supportive group where Cath knows your name, your goals and exactly how to get the best from you.
Never the same twice
Dice, coins, cards, dumbbells, kettlebells, steppers, medicine balls and more — endless variety keeps every session fresh and fun.
Offers & events all year
Look out for special offers, seasonal challenges and fun activities throughout the year — there's always something new to jump into.
Every level welcome
Got an injury or just starting out? Cath provides alternative exercises so the session always works for your body.
Online included
Train in the studio and you get access to Cath's online training sessions for free — so you can keep moving from home too.
A real community
Clients call it their "In House family" — a warm, welcoming crew who cheer each other on and make showing up the best part of the day.
Early birds, busy mums, cherished seniors — there's a spot for you
Life doesn't run on a one-size-fits-all schedule, so neither do we. Pick the time that fits your day.
Don't take our word for it
"Since starting training with her a year ago, I've been able to build my strength up, lose 12kg and continue working on my fitness. She tailors the classes to my individual needs. The accountability is great. I highly recommend her classes and PT sessions!"
"I'm 64 and have trained with Cath for over 10 years — the longest I've ever stayed with a group. She's created an In House family where everyone is welcoming and encouraging. Over the years I've achieved things I never thought I could. I love my In House family and I know you will too."
"Eight months ago my doctor advised I had high blood pressure and needed medication. I asked for time to bring it down with exercise — and started with Cath. Today my doctor says I don't need medication; my blood pressure is back to normal. This experience has changed my life. The best PT I've ever had."
"Highly recommend! Each session is different and fun. Cath is motivating and provides alternative exercises if you have any injuries. Give it a go — you won't regret it!"
"Cath creates a low-key, accepting, friendly environment — she keeps me motivated and gets results. Great for all ages: even if you're over 30, 40, 50, you can participate and benefit."
"A fabulous trainer — I've actually stuck with her, instead of starting well and finding myself back on the couch within weeks! I've made awesome friends, exercised, and even managed a 10km run with lots of support. Kind, and pushy when she needs to be, always with a laugh. I cannot recommend Cath enough!"
