STRENGTH, SPEED, POWER AND AGILITY
WHO WE ARE
Play Strong Performance helps young athletes, college players, adults, pro & semi-pro athletes develop the strength, speed, power and agility needed to perform at their best in their sport.
Based in Marrickville, we deliver structured strength and conditioning for athletes across basketball, volleyball, soccer, AFL and other sports. Our coaching focuses on building athletic ability, confidence and long-term development.
1. STRENGTH
We build the foundation to produce and absorb force, control movement and handle the physical demands of every competitive sport.
2. SPEED
We teach athletes how to accelerate faster, cover ground efficiently and create separation when it matters.
3. JUMPING ABILITY
We develop the strength, power and jumping mechanics needed to get off the ground with greater explosiveness.
4. AGILITY & COORDINATION
Brake, change direction and accelerate again to respond to the demands of the game. Improve body control, timing and the ability to organise movement efficiently under pressure.
HEAR IT FROM THE ATHLETES
"Training with Adam has been a game changer for my NBL1 career.
He’s helped me get stronger, improve my vertical jump significantly, and keep my knees and body healthy throughout the season.
Adam always goes above and beyond to make sure I have everything I need to succeed, and I can’t thank him enough for his support and dedication."
Ngā mihi, Jonni
"After 6 years of training with Adam I can confidently say he is the BEST strength and conditioning coach in Sydney.
During this time I went from not being able to touch the rim to a 40 inch vertical.
He didn’t just help me with jumping but overall made me stronger, more athletic, more confident and mentally tougher.
I couldn’t recommend Adam enough."
Luca Mesiti
"Suffering a third successive ankle injury and being ruled out of the rep season I found Adam.
Adam's training got me strong and resilient.
From Adam's training I gained the confidence to play strong and I have gone on the be recruited into one of the most successful school programs in Australia and awarded defensive player of the year in the best U18 div one team in the Waratah NSW state league 2025.”
Kyi Heperi
"Adam is simply one of the best basketball and strength & conditioning coaches in the field. The progress I've made under his guidance has been tangible and consistent, which speaks directly to the quality of his programming.
As a physiotherapist myself with a strong foundation in human movement and performance, I can say with confidence that Adam's knowledge is exceptional. He adapts intelligently to each individual rather than applying a generic template, and the way he communicates the rationale behind his programming is something I genuinely learn from, session after session.
For anyone serious about their development as a basketball player or athlete, Adam is exactly the coach you want in your corner."
"I’ve trained with Coach A for 5 years now and there’s no one else I’d want guiding me.
He’s built me into a true athlete — stronger, more explosive, and resilient, always helping me come back better from injuries.
Nobody builds bounce and strength like him.”
Roman Stathis
"Adam is one of the best strength and conditioning coaches that I’ve ever worked with.
He has helped me tremendously this past year and a half to get back into professional football.
There’s so much that I needed to work on in order for me to perform at the highest level and he did just that. He has worked tirelessly to help me strengthen a lot of my weaknesses.
From when I started to where I am now, there’s been significant improvements. Adam has certainly increased my speed, jumping and overall athletic ability. He has also increased my mental strength and positive mindset through training. He’s helped me develop great training habits to improve nutrition.
Adam is a well experienced, high performance coach who I would greatly recommend to anyone."
Ruon Tongyik
"Best strength and conditioning coach in Sydney! Found Adam more than 5 years ago when he was documenting his own dunk journey as a 5ft11 basketball player. Since I’ve joined and trained 2-3 days per week with him, I’ve been able to increase my vertical jump from 24 inches to 35 inches. The growth is insane, staying injury free at 34 years old. Highly recommend!"

"Whilst playing in high performing teams, I was undersized, but I could shoot.
If I’m honest though, my biggest limitation wasn’t ability, it was confidence. I often passed when I should have shot or attacked.
Looking back, I believe strength training would have changed that. Not just physically, but mentally. That’s a big part of why I coach today.
My own training journey mirrors what I teach.
I initially trained for aesthetics. But when I shifted my focus to performance, everything changed.
My body improved, but more importantly, so did my mindset.
That’s what I believe training should do.
Yes, we build strength.
Yes, we improve speed and vertical jump.
But ultimately, we build confidence.
Because when an athlete feels strong and capable, it shows in how they move, compete and carry themselves.
And that’s what it’s really about."
