## What is BODYMAX?

BODYMAX is a fitness application that builds and adapts personalized weekly workout programs. Unlike generic workout apps that use static templates, BODYMAX uses a deterministic AI engine that selects exercises, sets, reps, rest periods, and progression based on:

- Your fitness level (starting out, beginner, intermediate, advanced)
- Your training goal (muscle gain, strength, weight loss, general fitness, flexibility)
- Your available equipment and facility type (home bodyweight, home gym, small gym, standard gym, full gym)
- Your schedule (3-6 training days per week, 20-75 minute sessions)
- Your injuries and mobility limitations
- Your real performance data (RPE ratings, weight lifted, completion rates)

The system has a 4-session calibration phase where it learns your baseline, then continuously adapts volume, intensity, and exercise selection based on accumulated evidence.

## How It Works

1. **Build your profile** — Goals, equipment, schedule, experience level. Takes 2 minutes.
2. **Get your plan** — BODYMAX builds a structured weekly program around your setup.
3. **Train with guidance** — Video demos, rest timers, rep logging — all tracked.
4. **System learns from you** — Every rep, weight, and effort rating builds your profile.
5. **Program evolves** — Weekly regeneration adjusts to what actually happened.

## Features

### Personalized Programming
Every workout is built specifically for the user. The V2 generation engine considers 2,470 exercises and filters them through equipment gates, injury blockers, demographic rules, and family-based rotation to prevent repetition.

### Adaptive Progression
The system tracks RPE (Rate of Perceived Exertion) per set, completion rates, and training volume. After calibration, it adjusts:
- Weight suggestions (increase, hold, or decrease)
- Rep ranges
- Set counts
- Exercise rotation and variation
- Deload detection when fatigue is high

### Smart Exercise Selection
Exercises are matched to the user's facility type. A home-only user will never see barbell or machine exercises. Equipment filtering is enforced at every code path — generation, replacement, backfill, and suggestion endpoints.

### Injury-Aware Training
Users can report injuries by body area (knee, back, shoulder, hip, ankle, wrist, neck, elbow). The system blocks movement patterns associated with each injury:
- Knee: blocks squat, lunge, plyometric patterns
- Back: blocks hinge, deadlift patterns
- Shoulder: blocks push, shoulder isolation patterns

### Recovery Monitoring
Fatigue and recovery scores are tracked per session. The system detects rising fatigue trends and can recommend lighter sessions or rest days.

### Cardio Integration
Smart cardio blocks are inserted into training sessions based on the user's goal, available equipment, and the preceding strength session. The cardio engine prevents lower-body cardio after leg-dominant sessions and respects weekly interval caps.

### Video Exercise Library
1,900+ exercises with video demonstrations. Each exercise has verified video content, primary muscle classification, equipment requirements, and movement pattern tags.

## FAQ

**Is BODYMAX suitable for beginners?**
Yes. BODYMAX adapts to your fitness level during onboarding and uses a calibration phase to understand your baseline. Beginner-unsafe exercises (like pull-ups) are automatically blocked.

**What equipment do I need?**
None required. BODYMAX supports full bodyweight training, basic home gym setups, and commercial gym environments. You select your facility type during onboarding.

**How is this different from a generic workout app?**
BODYMAX doesn't use templates or LLM-generated workouts. Every exercise is selected from a verified database using deterministic rules that account for your specific constraints, equipment, injuries, and performance history.

**Can I change exercises I don't like?**
Yes. Every exercise has a 3-dot menu with options to replace it, report equipment unavailability, or mark it as disliked. The system remembers your preferences permanently.
