Performance Coaching for women in strength

and physique sports

No excuses. No shortcuts. Just strength.

Welcome to StrongAF

Brought to you by The Female Strength Coach

You've outgrown coaches who only cover half the picture.
Strength. Physique. Competition. All of it.
Gemma O'Brien - "The Female Strength Coach" - coaches driven women to get as strong as possible, build real, lasting muscle, transform their body and minds and realise what they are truly capable of - in training and in life

Built around your goals

Whether you're chasing your first competition or just starting to get serious about training, your programming is built around you — not a generic template. It's shaped by where you're at right now, what you're working toward, and your body's actual needs, so every session has a clear purpose behind it that gets built upon, week after week.

The mental & the physical

Performance isn't just physical. Confidence, consistency, dealing with pressure — whether that's competition day or just showing up when motivation dips — all of it gets coached, every check-in, every week. You're not left to figure out the mental side alone while someone else just hands you a program. It's built in from day one. We don't negotiate on this.

Fuel for Performance

No fasting protocols. No unnecessary restriction. Whether you're building your first real strength or training for the platform, if you're working hard, you eat to fuel it — full stop. Food is treated as a performance tool, not something to fear or minimise. You're building something real and lasting, and that requires fuelling your body, and understanding what works and what does not.

Good morning Gemma!
I weighed myself today. I started this process being 106kg.

Today I am 101.3kg in just 2 weeks!

I am blown away to say the least!

I am not starving or faint eating on your program. Thank you so much!

It's only up (well technically down) from here!

I am so stoked Gem, I have finally added some weight on - 2kg! Its really starting to show in my lifts and my physique. Overall feeling great with daily movements and strength is definitely going up. I've go to much more energy to really nail down the training. Thank you again, I can't wait for the checkin next week. You are the goat!
