The personal training app in German – and in 40 other languages

Wouldn’t it be great if you could use your most important work tool in your own languae – Whether that’s creating workout plans, tracking client progress, or managing your coaching business? For personal trainers, the software they use daily isn’t just about features; it’s about working efficiently in a language that feels natural.

Trainero offers exactly that. The platform is available in over 40 languages, fully translated for both coaches and their clients. Whether you’re working in German, English, Spanish, or any other supported language, everything from the exercise library to client communication works in the language you choose.

More Than Just Translation

Many fitness apps claim to support multiple languages, but in practice, you often find a mix of translated menus with English-only exercise descriptions, or a client app in your language while the coach dashboard remains in English.

Trainero takes a different approach. The entire platform, every feature, every menu, every notification works in the language you select. This applies to both the coach interface and the client app.

Here’s what works in your language:

  • The coach app where you build programs and manage clients
  • The client app that your clients use daily
  • Exercise library with descriptions and instructions
  • All system notifications and reminders
  • Documentation and support materials

This means a personal trainer in Munich can work entirely in German while serving clients who use the app in Turkish, Polish, or English, all through the same platform.

Why Language Matters in Coaching Software

Language might seem like a small detail when you’re comparing features and pricing. But it affects how your clients actually use the platform.

Clients Follow Instructions More Accurately

When someone reads an exercise description in their native language, they understand the movement better. This leads to better form, fewer questions about what they’re supposed to do, and ultimately safer training.

Higher Engagement and Retention

Clients use apps more consistently when everything is in their own language. They log workouts more often, check their progress more regularly, and generally stay engaged longer. For personal trainers, that translates directly to better retention rates.

Access to International Clients

If you’re comfortable working with clients remotely, language support opens up new markets. You can serve German-speaking clients anywhere in the world, or work with international clients in your local area without needing separate tools for each language group.

Growing Beyond Your Local Market

Some trainers use the multilingual features to expand into online coaching. Instead of being limited to clients in your city or region, you can work with people anywhere who speak a language you’re comfortable with or hire coaches who speak other languages to serve those markets.

How It Works for Clients

From the client’s perspective, the experience is straightforward. When they first open the Trainero app, they select their preferred language. Everything then appears in that language: workout plans, exercise instructions, nutrition guidance, messages, and progress tracking.

Which Languages Are Supported?

Trainero supports over 40 languages. Here are some of the main ones:

European languages: German, English, French, Spanish, Italian, Portuguese, Dutch, Polish, Russian, Swedish, Norwegian, Danish, Finnish, Czech, and many others.

Asian languages: Chinese (both simplified and traditional), Japanese, Korean, Thai, Vietnamese, Indonesian, and more.

Other languages: Arabic and Hebrew (with right-to-left text support), Turkish, and additional languages covering most global fitness markets.

Practical Examples

The Online Coach with International Clients

A trainer in Hamburg started with local, German-speaking clients. As he built his online presence, he began getting inquiries from German speakers in other countries—Switzerland, Austria, and expats living abroad. Later, English-speaking clients in Germany also started reaching out.

Instead of needing separate tools or turning away non-German clients, he uses Trainero for everyone. He works in German, and clients see everything in whichever language they prefer. The daily workflow stays simple despite serving clients in multiple languages.

A Gym with International Members

A gym in Frankfurt has members from various countries—some German, some international workers, some long-term expats. Rather than offering the training app only in German (which would exclude many members) or only in English (which would feel foreign to German members), they use Trainero’s multilingual support.

Each member gets the app in their preferred language. The trainers work in German, and everything still functions smoothly across the different language groups.

White Label Options

Trainero also offers white label branding, which means larger gyms or fitness companies can have the client app customized with their own branding while keeping all the multilingual functionality. This is useful for businesses that want to present the app as their own while serving an international client base.

Getting Started

If you’re a personal trainer, you sign up, select your language, and start building programs. When you add clients, they choose their own language preference in the app. That’s it—no complicated setup or configuration.

For gyms or larger businesses, the process is similar, just with the option to add multiple trainers and potentially customize the branding.

A Note on Cultural Differences

Having the software in multiple languages solves the technical side of working with international clients. But it’s worth remembering that different cultures also have different approaches to fitness, nutrition, and trainer-client communication. The software handles the language part; understanding cultural preferences is something you develop through working with diverse clients.

Who Benefits Most from Multilingual Support?

Multilingual software is most useful if you:

  • Work in a city with international residents (expats, students, workers)
  • Want to offer online coaching beyond your local area
  • Run a gym with diverse membership
  • Plan to hire trainers who speak different languages
  • Serve clients who relocate frequently but want to continue training with you

Even if you primarily work with clients who speak your language, having multilingual capability means you’re not turning away potential clients simply because of language. It removes a barrier that many other trainers still have.

Conclusion

Trainero’s multilingual support isn’t a gimmick—it’s a practical feature that removes language as a limiting factor in who you can train. Whether you’re working with a diverse local client base or building an online coaching business, having software that works in over 40 languages means you can focus on training rather than worrying about whether clients will understand their workout plans.

The platform handles the technical side of language support automatically. You work in your preferred language, your clients work in theirs, and everything functions smoothly in between.

Trainero offers a 14-day free trial if you want to test the platform. You can see how the multilingual features work in practice and whether the software fits your workflow.
