Online Marketplace for NASM Trainers

Connect clients with certified fitness experts for specialized training services.

The Problem

NASM certified trainers often struggle to find clients seeking their specialized services. They spend countless hours on generic platforms competing with unqualified trainers, making it hard to showcase their expertise in specific areas like weight loss, strength training, or sports performance. Meanwhile, clients searching for trainers with particular qualifications have no easy way to filter by certification or specialty—they're left scrolling through endless profiles hoping to find the right fit. This mismatch leads to trainers with valuable expertise sitting idle while motivated clients give up on finding qualified help.

The Solution

Build a specialized marketplace that connects clients with specific fitness needs to NASM certified trainers. Trainers can create detailed profiles showcasing their certifications, specialties, and services—from personalized meal planning to sport-specific training. Clients can search and filter by specialty, read reviews, and book sessions directly. The platform verifies NASM credentials, ensuring quality and trust on both sides.

How it works:

1

Trainer Signs Up

Creates profile with NASM credentials, specialties, and services offered

2

Platform Verifies

NASM certification is verified to ensure quality and trust

3

Client Searches

Filters trainers by specialty, location, price, and availability

4

Book & Pay

Secure booking with integrated payments and scheduling

Market Research

The personal training market is growing rapidly, with over 400,000 NASM certified trainers in the US alone. Clients are increasingly searching for specialized fitness help, creating a clear opportunity for a niche marketplace.

  • 3,600+ monthly searches for "NASM personal trainer" and related terms
  • Personal training is a $40B+ market in the US with 5% annual growth
  • Market is not saturated—trainers are actively seeking more clients
  • Post-pandemic shift to online and hybrid training creates new opportunities
  • Clients willing to pay premium for certified, specialized trainers

Competitive Landscape

Existing platforms are either too broad (generic fitness marketplaces) or too expensive for independent trainers. None focus specifically on connecting NASM-certified trainers with clients seeking verified expertise.

Thumbtack

General services marketplace with fitness category. No certification verification, high competition.

Your Opportunity

No platform specifically targets NASM-certified trainers with verified credentials. By focusing on this niche, you can attract quality trainers who want to stand out and clients who value verified expertise.

1. Project Setup

Create a new Next.js 14 project for a NASM trainer marketplace. Set up: Project structure with App Router and TypeScript. Supabase for database with tables for trainers (profile, certifications, specialties, services, availability), clients (profile, preferences), bookings (trainer_id, client_id, service, datetime, status, price), and reviews. Supabase Auth for both trainer and client signup flows. API routes for trainer search, profile CRUD, and booking management. Include environment variables setup, proper error handling, and a clean folder structure with /app, /components, /lib, and /types directories.

2. Core Feature

Build the trainer search and discovery feature for the NASM marketplace. Requirements: Search page with filters for specialty (weight loss, strength, sports performance, nutrition), location (city/zip with radius), price range, availability, and rating. Trainer cards showing photo, name, verified NASM badge, specialties, rating, price range, and availability preview. Detailed trainer profile page with full bio, certifications list, services offered with pricing, reviews, and booking calendar. Implement with Supabase full-text search or Algolia integration. The user flow: Client lands on search → applies filters → browses trainer cards → clicks to view profile → selects service and time → proceeds to booking.

3. Landing Page

Create a landing page for the NASM Trainer Marketplace using Next.js and Tailwind CSS. Include: Hero section with headline "Find Your Perfect NASM Certified Trainer" and subheadline about connecting with verified fitness experts. Split CTA for "Find a Trainer" and "Join as Trainer". How it works section with 4 steps (Search, Compare, Book, Train). Benefits section for both clients and trainers. Trust indicators showing "400k+ NASM Trainers", "Verified Credentials", "Secure Payments". Featured trainers carousel (placeholder). Email capture for early access. Clean, modern design with a fitness-inspired color scheme (energetic blue/green accents on white). Mobile responsive.

4. Branding Package

Create a branding package for TrainerMatch (or similar name), a marketplace connecting clients with NASM certified fitness trainers: Logo concept - Simple, modern mark combining fitness/movement with connection/matching theme. Works at small sizes for app icon. Color palette - Primary (energetic, trustworthy), Secondary (calming, professional), Accent (action/CTA). Typography - Heading font that conveys strength and professionalism, body font that's clean and readable. Provide hex codes, font names (Google Fonts preferred), and usage guidelines. Include variations for light and dark backgrounds.

5. Stripe Connect Integration

Implement Stripe Connect for the NASM trainer marketplace with Next.js. Requirements: Trainer onboarding flow to create Connected Accounts (Express type for simplicity). Booking checkout that creates PaymentIntents with automatic commission split (20% platform, 80% trainer). Webhook handling for payment confirmations and updating booking status. Trainer dashboard showing earnings, pending payouts, and payout history. Handle refunds for cancelled bookings. Include proper error handling, idempotency keys, and test mode setup.
