When I started working with Zack, I couldn’t even do a single squat. I was out of shape, low on confidence, and unsure if personal training would even work for me.

His training style is motivating, supportive, and personalised for real people—not just athletes. I’m so grateful for this journey and proud of what we’ve achieved together.
