Harley AI: A Fitness Trainer's Best Friend Built by Doctors. Trained by a Fitness Pro. A personal trainer with over 100 active clients told two doctors exactly what he needed. They built it. Harley works for you. Your clients, your business, your way. We make money when trainers subscribe. That's it. We don't sell data and we don't run ads. WHAT HARLEY DOES AI Workout Builder Tell Harley what you need and it builds the workout. Exercises, sets, reps, tempo, rest periods, coaching cues. The exercise library has 2,600+ entries drawn from real sports science research, and when Harley writes a program, the reasoning traces back to actual sources. Smart Scheduling and Booking Day, week, and month views. Clients book straight from your storefront. Session credits, group classes, and waitlists are all managed in one place. You stop being a receptionist. Payments Built In Your money goes directly to your Stripe account. Accept payments for sessions, class packs, and products. Invoicing, payment history, and revenue tracking live in one dashboard. Client Management Workouts, progress, body stats, PRs, nutrition, health data. Assign programs, send messages, and manage your full roster from your phone. One screen per client, everything visible. Nutrition Tracking Clients search foods, log meals, and track macros. You set the targets and you see everything they eat. The food database is USDA FoodData Central, the same source dietitians use. Recovery-Aware Training Connect Whoop (Apple Watch and Garmin coming soon). Harley reads recovery scores and adapts workout intensity based on how recovered your client is. You push when they're ready and pull back when they're not. One-Click Migration from Trainerize Bring your clients, workouts, exercises, programs, and custom videos over in minutes. Artha: Your Business Brain Artha tracks your income, monitors your churn rate, and helps you price your services. Every trainer deserves to actually know their numbers.

The exercise library, coaching cues, and safety guidelines come from curated science sources. When Harley recommends a program, you can trace exactly why it chose what it chose. Two physician co-founders. A hardworking New York trainer who shaped the product from day one. Patent-pending AI that remembers what matters and filters out noise. Your data stays yours. harley.dnai.systems Harley provides fitness and nutrition tools for personal trainers and their clients. It is not medical advice. Always consult a healthcare provider before starting any exercise or nutrition program. Artha provides business analytics and income insights, not financial, tax, or investment advice. AI-generated workouts and coaching cues draw from a curated exercise science knowledge base, and a qualified trainer should review programs before assigning them.
