Gerarde Carlton

With 5 years in the industry, I have developed a broad range of approaches to fitness and have built a reputation of client success. I believe that community and culture are king in fitness today, and that competition is one of the biggest sources of confidence. If I'm not competing myself or coaching athletes through one, you can most likely find me networking with a sporting body or a fitness race to make it accessible.

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.
