A Bit About Me
With 15 years of experience in the fitness industry, I’m passionate about helping people become stronger, healthier, and more confident through sustainable training and balanced nutrition.
My approach is built around structure, accountability, and long-term results — not quick fixes.
I design tailored programs that improve strength, cardiovascular fitness, and overall well-being, while also educating clients on how to maintain progress outside the gym.
Alongside my face-to-face sessions, I’ve also launched online coaching this year, allowing me to work with clients remotely and provide more flexibility and support to those training from home.
Based on Sydney’s Northern Beaches, I’m committed to helping every client perform at their best and build a lifestyle that supports lasting health and confidence.

I started training with Zac 6 months ago. In that time, I have surpassed what I thought was possible - building my strength and actually enjoying going to the gym.
He listened to my goals, designed a program and has continually made adjustments for a recovering injury.
He holds me accountable, pushes me, but also listens to me. We have good chat, and the time just flies.
Highly recommend.

Amazing trainer — supportive, professional, and motivating. Every session is challenging but rewarding, and their attention to technique and mindset has helped me achieve results, corrected my posture and built my strength. Couldn’t recommend more highly!

I started training with Zac 12 months ago. My fitness and strength have improved significantly, more than with previous exercise programs. At middle age, I really appreciate the improvements in movement and stamina.
Zac is very knowledgeable and can adapt to individual needs and concerns. In addition to Zac’s effective training and support, his approach is very professional whilst also engaging. I highly recommend Zac as a personal trainer.

I’ve been training with Zac since 2024 when I returned from living abroad and getting myself in a pattern of enjoying myself too much. Since the start, he’s been communicative and adaptive to my needs, assisting me to establish a series of goals and eating challenges (vegetarian) to add mass whilst toning excess weight. My program covers the key muscle and food groups, giving me confidence with proper techniques to better manage my lifestyle in and out of the gym. When I’ve injured myself, Zac’s been there during the recovery with a modified program to ensure no further injuries to get me back to my best. Through our relationship, he understands my needs and is always available to assist.

I have been training with Zac for over 10 Years. I hated gyms and found the whole environment very intimidating.
Initially starting with an injury and then continuing a strength, fitness and weight loss journey.
Zac is knowledgeable in nutrition, fitness and rehab and catered his programs to suit my individual needs.
He has a great sense of humour, is extremely motivating and supportive whilst recognising my social lifestyle. He makes each session fun yet challenging.
My overall journey in fitness and mindset has changed for the better. I am more mentally motivated whilst still being able to enjoy life.
I now visit gym 3 times a week and am more confident in myself thanks to Zac.
