Project Overview & Architecture
YourGymBro is an all-in-one personal training app built around an AI coach called GymBro AI. It plans weekly routines, runs live workout sessions with set-by-set logging, adapts weights and reps from your previous performance, and tracks nutrition, steps, muscle recovery and long-term progress. A daily dashboard brings it together with a training-day briefing, calorie and protein targets, step count, consistency tracker and workout streak, while all workout logs, photos and settings are kept on the device and can be exported or imported as a JSON backup.
Core Capabilities & Engineering
GymBro AI Coach
Conversational trainer that reviews your monthly muscle volume, suggests where to focus, helps break PR plateaus and can generate a routine (for example a Push Day) that you import into your planner with one tap.
Live Workout Mode with Adaptive Advice
Active session timer, warm-up and cool-down blocks, weight/reps logging per set, previous-best and target values for each exercise, pyramid-setup suggestions, rest-period countdown with skip/±15s, and voice input.
Weekly Planner & Exercise Library
Build custom routines and assign them to days of the week. Searchable exercise database filtered by muscle group, target muscle and difficulty, with form animations, specifications, recovery time and step-by-step instructions.
AI Calorie & Nutrition Tracker
Log meals by scanning a photo, describing them in text, manual entry or saved meals, with daily calorie, protein, carb and fat targets and a meal log split by breakfast, lunch and dinner.
Muscle Recovery & 3D Volume Map
Recovery percentage for every muscle sub-group based on sets logged in the last 72 hours, an interactive 3D/2D body heatmap of training volume, push/pull and upper/lower balance ratios, and AI recommendations on what to train today.
Steps, GPS Walks & Progress Analytics
Hardware pedometer with 24-hour step distribution, live outdoor walk tracking with GPS route, plus body measurements, personal records with projected 1RM, progress photos, training history calendar, goals and achievement badges.
