The Real Problem

It's Not Your Fault You've Been Struggling.

Most programs fail because they hand you a generic workout, ignore your nutrition, and expect you to figure out the rest. They don't account for your schedule, your lifestyle, or the fact that motivation alone doesn't last.

That's not a you problem — that's a bad program problem.

Defined Bodies is built differently.

About Me
Samantha Hobley — Defined Bodies Personal Trainer Perth

I Know Exactly Where You Are Right Now.

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 almost 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 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 hold a Certificate IV in Fitness and have spent over 10 years in the fitness industry helping women across Perth and online lose weight, build strength, and finally break the cycle of starting over. But the credential that matters most to me is the 50+ women who no longer avoid their own reflection.

What Clients Are Saying

Real Clients. Real Results. No Gimmicks.

Don’t just take my word for it. Here’s what my clients actually say.

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.

Himesh

Pushed further than he thought possible.

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 💪🏼

Kara

6kg down in 4 weeks. Clearer mind, zero anxiety.

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.

Bec

Fixed muscle imbalances in 6 weeks.

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!!

Georgia

Nutrition on track. Confidence in the gym.

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.

Dina

Every session challenging, motivating, enjoyable.
