At ABC Trainerize, our mission has always been to empower fitness professionals with the tools they need to deliver real results, from personalized training programs to progress tracking and client communication. But training doesn’t stop at the gym.
For years, our trainers have told us their clients ask the same questions over and over:
- “What protein powder should I take?”
- “Do I need supplements?”
- “How can I stay consistent with my nutrition?”
Until now, those conversations were disconnected from your business; you’d give great advice, but you didn’t share in the value that recommendation created. That changes today.
We’re excited to announce our new partnership between ABC Trainerize and Gainful, bringing personalized, science-backed nutrition directly into your coaching ecosystem and giving trainers a new way to earn.
💡 What Is Gainful?
Gainful is a leading performance nutrition brand that believes in personalized, science-backed nutrition for every body.
Their products, from protein to hydration, pre-workout, and recovery, are designed to be clean, effective, and customizable for each client’s unique goals and dietary needs.
With Gainful, every trainer can feel confident recommending supplements that are:
- Personalized: Blends tailored to each client’s needs and preferences.
- Science-Backed: Developed with research-driven formulas for performance and recovery.
- Clean: Free from artificial fillers and unnecessary additives.
- Trusted: Used and loved by athletes, trainers, and everyday fitness enthusiasts.
🤝 Why ABC Trainerize Partnered with Gainful
At ABC Trainerize, we believe great coaching goes beyond the workout.
It’s about helping clients stay consistent, feel better, and achieve their goals faster, and that includes fueling their bodies properly.
We partnered with Gainful because their approach to nutrition perfectly complements the way you coach: personalized, evidence-based, and results-driven.
Together, we’re combining:
- Personalized coaching (via ABC Trainerize)
- Personalized nutrition (via Gainful)
To create a powerful, integrated experience that supports your clients — and helps your business grow.

💰 The Triple Win: How Trainers, Clients, and Businesses Benefit
1️⃣ Better Results for Clients
Your clients get personalized nutrition recommendations from a brand you trust, designed to support their workouts, recovery, and overall well-being. When nutrition and training work together, clients perform better, recover faster, and stay consistent with your programs, leading to stronger retention and lasting results.
2️⃣ New Revenue for You
Through the Trainerize × Gainful Affiliate Program, trainers earn 20% commission on first orders and 10% on every recurring order for a year, creating a steady stream of income that grows with your impact. When your clients succeed, so does your business.
3️⃣ Stronger, More Holistic Coaching Businesses
By offering trusted, science-backed nutrition alongside your training programs, you position yourself as a complete wellness coach who supports every part of a client’s journey, from workouts to recovery to daily habits. This builds deeper trust, stronger relationships, and the kind of loyalty that fuels long-term growth.
🧠 Why It Matters
The best trainers know success isn’t just about great workouts — it’s about habits, accountability, and consistency.
Nutrition is the foundation of performance and recovery, but finding clean, trustworthy products that align with your coaching philosophy isn’t always easy.
That’s where Gainful stands out: every product is tailored, simple, and designed to support consistent progress.
Now, with ABC Trainerize × Gainful, you can integrate that same philosophy into your coaching — delivering results that speak for themselves.
