An AI-powered personal training platform with adaptive workout programming, nutrition tracking, real-time exercise form analysis via computer vision, and progress analytics — serving 5,000+ active users with 89% retention rate.

The Challenge
A fitness startup wanted to democratize personal training — making expert-level programming and coaching accessible at a fraction of the cost. Existing fitness apps offered generic, one-size-fits-all plans that users abandoned within weeks.
Project Timeline
Partnered with certified personal trainers and sports scientists to codify training periodization principles, exercise progression logic, and nutrition macro calculations.
Adaptive workout generator based on fitness level, goals, equipment availability, and recovery status. Progressive overload algorithms and deload week scheduling.
Real-time exercise form analysis using MediaPipe pose estimation, rep counting, and form correction feedback. Food photo recognition for calorie estimation.
React Native app with offline workout mode, Apple Health/Google Fit integration, social features, subscription billing, and App Store/Play Store launch.
Our Solution
AI generates personalized workout plans based on fitness assessment, goals (muscle gain, fat loss, endurance), available equipment, and schedule. Automatically adjusts weights, reps, and volume based on logged performance.
Computer vision via phone camera analyzes exercise form in real-time. Provides live feedback ("lower your hips more", "keep elbows tucked") and counts reps automatically. Reduces injury risk dramatically.
Snap a photo of your meal and AI estimates calories and macros. Barcode scanning for packaged foods. Daily targets adjust based on workout intensity and body composition goals.
Monitors training load, sleep data (Apple Health integration), and self-reported soreness to recommend deload weeks, active recovery days, and optimal training frequency per muscle group.
Body composition tracking, strength progression charts, workout consistency streaks, and AI-generated monthly progress reports comparing to similar users in the same demographic.
Community challenges, workout sharing, leaderboards, and optional live video coaching sessions with certified trainers for users wanting human guidance alongside AI programming.
Results
Client Feedback
“FitCoach is like having a personal trainer, nutritionist, and accountability partner in my pocket for $15/month. The form analysis caught my squat issues that were causing knee pain. I've made more progress in 3 months than in 2 years of gym-going alone.”
