What is the Precision Nutrition Certification?

You're a new breed of health and fitness pro. This is a new breed of education. The PN Level 1 Certification will teach you the methodology we've tested, refined, and proven with nearly 50,000 of our own clients.

Real-world coaching strategies for elite professionals.

Helping your clients transform their bodies can be diffucult and time-intensive. We’ll show you a better way. Using what we’ve learned from working with close to 50,000 people, we created a proven nutrition system you can follow to get better results with any client.

After 15 years in the fitness industry, we’ve watched fads come and go. That’s why we carved our own path, constantly tweaking, improving, and testing our methods based on the latest in nutrition, exercise, and psychology research.

Fast Company Magazine rated Precision Nutrition one of the most innovative companies in health and fitness.

- Eric Cressey, MA, CSCS

“What really makes a great coach, and what I think works so well in the PN Level 1 program — it’s not about telling someone to do something. It’s about knowing what questions to ask, and then leading the person in the right direction.

Our guarantee

Lots of companies guarantee their products. We guarantee our services, too.


Our students make a commitment to learn from us — and we make a commitment to help them become better coaches. In the end, our students decide for themselves: Was it worth it? If yes, they earn their Pn1 credentials and feel confident that they can help any client through a successful body transformation. If no, we give them a full refund.

That’s our promise. Try the PN Level 1 Certification for 45 days. If you’re not happy with what you learn, return your textbook and we’ll give you every penny back. We’re confident in what we do and we stand by our work.


We only take a small number of new students and teach them our proven nutrition coaching system. Spots are first-come, first-served and historically sell out in hours.

The general public price of the Precision Nutrition Level 1 Certification is $99 USD per month for 12 months. But when you join the free presale list today, you’ll get the opportunity to get it for only $79 USD per month or a one time payment of $799 USD — up to 35% savings.

If you decided to go back to school for a nutrition degree or to become a registered dietitian, you’d likely spend anywhere from $10,000 – $20,000 USD per semester. If you did a four-year degree, you’d be looking at spending upward of $40,000 – $100,000 USD.

The only problem? Most university courses lack real-world coaching opportunities. And most professors aren’t experienced coaches. That’s why many students find that they’re stuck once they graduate.

It’s also why, in the Precision Nutrition Level 1 Certification, we’ll share a proven coaching system that’s guaranteed to get results for your clients.

Indeed, after coaching 50,000 clients, we know what works. We’ve created a bulletproof system. And we’re making it available to you at a very affordable price.
