What Trainerize does well
Exercise library. 5000+ exercises with video demos, you can build a workout plan from ready blocks quickly. Best library in the industry.
Workout plans. Very refined UI for building plans, supersets, periodization, automatic progressions. Trainerize started as a pro-trainer tool and it shows.
Wide adoption. 100 000+ trainers globally means heavily tested API, stable uptime, many edge cases handled.
Integrations. Strava, MyFitnessPal, Apple Health, Google Fit, Stripe.
Where Trainerize falls short for European / multi-locale trainers
No local language localization. UI in English. Your 50-year-old client in Berlin or Warsaw won't use it.
Payments without local methods. Stripe US-version doesn't support BLIK, iDEAL, SEPA out of the box. Client pays by card, but you lose conversion from local payment methods.
No local phone support. Refund issue, invoice question — English email with 24h reply time.
Expensive. Pro plan with subscription billing for clients = $99+/m. Studio plan with multiple coaches = $250+/m.
No native booking-as-a-service. Trainerize has a calendar but bookings happen via Calendly / Acuity integration. Calendar = add-on, not core.
No multi-trainer / facility support. Trainerize is a SOLO-trainer tool. Studio with 5 trainers and 3 rooms = wrong fit.
What Fit.Expert does well
Multi-locale UI + support. 10 languages, local-language support including phone.
Local payment methods. Stripe integration optimized for European market. Client clicks BLIK / iDEAL / SEPA, enters their auth, paid.
Full package system. You create "10 sessions valid 60 days", system deducts, alerts on expiry. Not just subscriptions — discrete packages clients actually buy.
Sports facility support. If you run a studio with multiple trainers / rooms, Fit.Expert has multi-trainer dashboard, aggregated finance reports, team management.
Price. $15/m vs $25–250/m Trainerize. Real annual difference: $180 vs $300–3 000.
SEO-friendly profile. Your profile at fit.expert/your-name has JSON-LD, hreflang, sitemap — out-of-box SEO. Trainerize public profile has basic meta tags but less developed.
Where Fit.Expert has more to build
Exercise library. Trainerize has 5000+, Fit.Expert is growing its own. If a ready exercise library with video matters most, Trainerize wins.
Ecosystem maturity. Trainerize has 14 years of experience, Fit.Expert is younger. Edge cases (e.g. timezone conversions for international clients) sometimes need filing.
Direct tracker integrations. Apple Health, Google Fit — Trainerize has these, Fit.Expert is building them.
Concrete use cases
Solo trainer, 100% clients in your country, selling packages: → Fit.Expert. Local support, local payments, lower price, better package system.
Fitness-pro trainer with US/UK remote clients, workout plans are core offer: → Trainerize. Exercise library, mature API, international clients see a familiar UI.
Beginner trainer with 1–5 clients: → Fit.Expert (free tier). Check if you even need a paid tool. Trainerize 14-day trial OK, but $25/m is steep for a beginner.
Studio with 3 trainers and 2 rooms: → Fit.Expert. Trainerize doesn't natively support this — you'd have to hack it.
Corporate / gym with 20 trainers: → Fit.Expert (offers B2B support and custom integration).
Migrating from Trainerize to Fit.Expert
If you already use Trainerize and are thinking of switching — realistically 1–2 evenings:
- Export clients from Trainerize (CSV)
- Import to Fit.Expert (field mapping, 30 min)
- Workout plans — rewrite to the new system (longest, 2–4h for 10 clients)
- Notify clients: new booking link, install Fit.Expert app
- Cancel Trainerize subscription after 30 days (overlap buffer)
Verdict
Trainerize wins: global exercise library, ecosystem maturity, international clients. Fit.Expert wins: local market, local payments, packages, sports facilities, price.
For 90% of European trainers Fit.Expert has a better feature-to-price ratio. For 10% pro trainers with global clients Trainerize makes sense.
