The Real Problem
You're not lacking discipline. You're running the wrong programs, here's why the usual ones leave you stuck.
The same workouts on repeat. Your body adapts within months and stops responding.
Feels great, but it won't build the muscle your body needs to burn fat.
They work while you're on them, but the muscle goes and the weight comes back.
You're not the problem. The programs are.
Here's what I do instead
Because not that long ago, I was there too.
I know what it's like to avoid your own reflection. To get dressed in the morning and feel dread before the day has even started.
I know the Sunday night feeling. The “I'll start Monday” promise you've made so many times it doesn't feel like a promise anymore.
I know all of it. Not because I've read about it. Because I lived it.
At my heaviest I was 85kg and a size 14. I tried everything, calorie counting, cutting carbs, restriction diets that always ended in a binge. Gym memberships I barely used, because walking in felt like walking into a room I hadn't been invited to. I wasn't lazy. I wasn't lacking willpower. I just didn't have the right support.
Every time I fell off, the voice in my head got a little louder. You always do this. You have no discipline. You're never going to change.
Then I looked at a photo of myself and saw it clearly. Not just how I looked, but how I carried myself. The embarrassment. Wanting to disappear. That was the moment I decided it was my turn.
In 12 months I lost 20kg and dropped four dress sizes. But the number was the least interesting part.
I stopped avoiding mirrors. I started saying yes to things I'd been quietly declining for years, invitations, photos, a day at the beach. The constant noise (what do I look like, what are they thinking) gradually turned down.
And in that quiet, I found something I hadn't had in a long time. Myself.
I'm now 30kg down in total, and I've built the knowledge and experience that I want to pass on.
I became a trainer because I wanted to be the coach I needed when I was at my lowest. The women who need this most have convinced themselves they're not ready yet. That they need to lose weight before seeing a trainer.
You don't. That's exactly what I'm here for.
I'm a qualified female personal trainer with a Certificate IV in Fitness and more than 10 years in the health and fitness industry. I coach women at Doherty's Gym in Perth and online across Australia, running training sessions and full nutrition plans that are enjoyable, sustainable, and actually work. That's the Coach Sammi Method.
The certifications matter. What matters more is the woman who walks out. Lighter. Stronger. Back to herself.
I share this not to impress you, but to show you that I know this path. Every part of it.
The Coach Sammi Method is my approach to women's weight loss and body recomposition, built on four things that actually work: progressive strength training, whole-foods nutrition, sustainable habits, and mindset work.
The nutrition runs on whole foods with simple ingredient lists, nothing processed, grounded in evidence rather than fad diets. It rejects crash dieting, group fitness, and restriction. I built it through my own 30kg transformation. It's helped 50+ Australian women lose weight and keep it off.
What Clients Are Saying
Don’t just take my word for it. Here’s what my clients actually say.
Bec
“Sammi really takes the time to understand your body and goals. Nothing generic here. She fixed more of my muscle imbalances in 6 weeks than I managed in 2 years of gymming. It's completely tailored, and if something doesn't work she's more than happy to change it.”
Ann-Marie
“Sam has been my coach since mid-2023 and she's been such an integral part of my fitness journey… I've learnt so much about myself, my capabilities, nutrition and self care through her. 10/10 would recommend. She is really one of a kind 💜”
Raquel
“Sam is such a wonderful coach! I feel amazing after every workout. Her guidance and support along the way has been unmatched. We have a great laugh, she pushes me past my limits and the results are there to prove it! She's amazing!”
Kara
“4 weeks in and I've dropped 6kg. But honestly the bigger win is the mental clarity. No more brain fog, no more anxiety about food or the gym. Coach Sami doesn't just train you, she supports you through life's stresses too. THANK YOU 💪”
Georgia
“Sammi is the perfect balance between supportive and pushing you to your limits. She made me feel so comfortable in the gym, always showing me new things and teaching me about nutrition and understanding my body's cycle. Love this girl!!”
Dina
“Training with Coach Sami has been an amazing experience. She's friendly, funny, and incredibly knowledgeable, but don't let the laughs fool you, she's tough when it counts. Every session is challenging, motivating, and actually enjoyable.”
Himesh
“Training with Coach Sami has been one of the best decisions I've made for my fitness journey. She's knowledgeable, professional, and genuinely supportive. She knows exactly when to make you laugh and when to push you beyond what you thought you were capable of. Every session challenges me to be better, stronger, and more disciplined.”

Not at all. Most of my clients start as complete beginners. I build your program from scratch around your current fitness level and progress you at a pace that's right for you.
Not even close. Several of my clients started in their 40s and have had some of the best transformations I've seen. Your metabolism and hormones change as you get older, which is exactly why having a coach who understands that matters. I adjust your training and nutrition to work with your body, not against it.
No. This is one of the biggest myths in women's fitness. Women don't produce enough testosterone to build bulky muscle. What strength training actually does is help you lose fat, build lean definition, and boost your metabolism so you burn more calories at rest. Every one of my clients who was nervous about weights wishes they'd started sooner.
Both have a place, but if I had to choose one it would be strength training every time. Cardio burns calories while you're doing it, but strength training builds lean muscle that increases your metabolism long term. Most of my clients do a combination. The balance depends on your goals and where you're starting from.
Most of my clients train 3–4 times per week, with 1–2 of those sessions with me. Sessions run 45–60 minutes. I take your schedule into account when I build your program, so it's designed to fit your life, not disrupt it.
Most of my clients train 3–4 sessions per week, each 45–60 minutes. 1–2 of those are with me, and the rest follow the program I build for you so you can train on your own. Between sessions you follow your nutrition plan, check in with me through the app, and live your life. I also programme rest days and recovery into your plan. Pushing harder every single day isn't the goal. Consistency over intensity is what actually gets results.
You get a fully personalised nutrition plan with calorie and macro targets, complete meal guides, and recipe ideas. I take into account your food preferences, lifestyle, and any dietary requirements. No one-size-fits-all meal plans here.
Absolutely not. I don't believe in cutting out food groups or giving you a meal plan you'll hate by day three. Your nutrition plan is built around foods you actually enjoy, with the right calorie and macro targets to hit your goals. If you love chocolate, we work chocolate in. Sustainability is the whole point.
Most of my clients start feeling the difference within the first 2–3 weeks and see visible changes within 6–8 weeks. Lasting weight loss takes consistency. I'll keep you accountable and on track the whole way.
That's actually most of my clients. The reason nothing worked before usually isn't effort. It's that the approach wasn't right for you. A generic program can't account for your body, your schedule, or why you keep falling off track. I build everything around you specifically, and I stay in your corner to adjust things when life gets in the way.
Life happens. That's completely normal. Missing a session doesn't mean starting over. I adjust your program around what's actually happening in your life, and we pick up right where you left off. The whole point of coaching is having someone to pull you back on track before a missed day turns into a missed month.
That's exactly what the online and hybrid programs are designed for. Your program is fully accessible through the Defined Bodies app so you can train wherever you are, whenever works.
It depends on whether you're training with me in person at Doherty's Gym in Perth or online from anywhere in Australia, and how often we work together. Rather than list prices that won't mean much without context, I'd rather understand where you're at first. Book a free strategy session and I'll walk you through what makes sense for you, no pressure either way.
For in-person and hybrid training, we train at Doherty's Gym in Perth. You can either pay $15 per session or grab a weekly membership for $17. It's one of the most affordable gyms in Perth. For online coaching, you can train at any gym or even from home. I'll design your program around whatever equipment you have access to.
Yes. My online coaching program is available Australia-wide. You get the same custom training program, full nutrition plan, and direct message support as my in-person clients, plus weekly check-in calls in place of the weekly in-person session. The only difference is we're not in the same room. Many of my best results have come from online clients.
An app gives you a generic plan and hopes for the best. I give you a program built specifically for your body, your goals, and your life, and then I coach you through it. I adjust your training and nutrition as you progress, answer your questions in real time, and hold you accountable when motivation dips. That's the difference between information and transformation.
I specialise in women's weight loss and body composition, but I work with all clients who are serious about their goals. If you're ready to commit, there's a program for you.
An in-depth consultation that includes a movement and strength assessment, so I can actually see where you're starting from rather than just take your word for it. Then a proper conversation about your goals, your current routine, and what's been holding you back. You'll walk away with a clear picture of where you're at and how I'd approach building a program for you. No sales pressure. If it's not the right fit, no hard feelings.
Your first strategy session is completely free. No commitment, no awkward pitch. Just a clear plan and a real starting point.
