About GP Nutrition & Fitness
Helping you build lifelong strength, better health and greater independence.
THE STORY BEHIND THE METHOD
I’m Gemma Petty, the founder of GP Nutrition & Fitness, and I have over 20 years of experience in fitness, exercise and supporting people to improve their health, fitness and performance.
My approach is simple: I don’t believe your age, diagnosis or current level of fitness should define what you’re capable of.
I work with adults who want to become stronger, improve their health, stay active and maintain their independence as they get older. I also have a particular interest in supporting people living with long-term health conditions, including arthritis, cardiovascular conditions and those recovering from illness or stroke.
My role isn’t to promise a miracle cure or tell you that everything is possible regardless of your circumstances.
It’s to understand where you are now, work within what is appropriate for you, and help you discover what you are capable of.
Over more than two decades in the industry, I’ve worked with a wide range of people — from Olympians and international rugby teams to everyday individuals and people living with medical conditions.
That experience has taught me that there is no single definition of fitness and no one-size-fits-all approach to health.

Exercise and nutrition for real life
My work brings together evidence-based exercise and nutrition to help people improve their health and physical capability in a way that fits their lives.
That might mean building strength and mobility, improving cardiovascular fitness, managing weight, developing healthier eating habits, returning to exercise after illness or injury, or simply becoming more confident in what your body can do.
The goal isn’t perfection.
It’s realistic, sustainable progress that helps you stay strong, healthy and capable for the long term.
Why this work matters to me
I also understand personally that health isn’t something we should take for granted.
Living with autoimmune arthritis has given me a different perspective on what it means to live with a lifelong health condition. I’ve had to learn how to adapt, manage my own limitations and focus on what my body can do rather than only what it can’t.
I’ve also experienced the impact that medical conditions can have on people I care about, including losing friends and loved ones.
Those experiences have strengthened my belief that people deserve support that is honest, evidence-based and realistic.
I won’t write you off because you have a medical condition.
But I also won’t sell you false hope.
I’ll work with you to find the right approach for your health, your abilities and your life.
