The Core Engine

Welcome to the Execution Matrix. This is not a spreadsheet; it is an intelligent, self-regulating algorithm designed to take you from a beginner to an elite Grandmaster across decades of lifting.

• Lift Styles (Top Right): Instantly shift the algorithm's entire mathematical framework. Toggle between Powerbuilding, Powerlifting, or Bodybuilding, and watch the app instantly recalculate your Sets, Reps, and Target RPEs across all 1,560 weeks.
• Cloud Syncing: Your data is vault-secured on Firebase. Log in from any device, anywhere in the world, and instantly resume your exact week.
• Auto-Rest Timer: The moment you log a weight, the tracker analyzes the movement and fires an optimized rest timer (3 mins for heavy compounds, 1.5 mins for isolation). Let the app think so you can breathe.
• 1-Rep Max Projection: Enter your working sets, and the app instantly crunches the Epley Formula to project your true 1RM. Watch this number surge over the years.

Absolute Beginners: Don't Panic

Think this app is overkill or too complex? It's actually the opposite. You do not need to understand training volume, ULPPL splits, or fatigue management to get massive results. The Execution Matrix handles all the math, science, and scheduling for you. You just have to lift.

• Step 1 — Pick Your Week: On the left sidebar, tap Week 1. The app automatically builds your ULPPL split for you.
• Step 2 — Lift & Log: Look at the prescribed Sets, Reps, and Target RPE (Intensity). Lift the weight, type it in the box, and press Log.
• Step 3 — Rest & Repeat: The moment you press Log, the app's AI starts an optimized rest timer. Wait for the beep, then do your next set. The app manages your fatigue automatically!

The AI Coaching Suite

The Matrix actively prevents injuries and plateaus before they happen.

• The Target 🎯 Dropdown: Once you decrypt Phase 3, this system goes live. Tell the app your weakest muscle (e.g., Lats, Side Delts, Calves), and it will surgically inject pre-exhaust isolation movements to the top of your workouts.
• CNS Gating ⚡: The nervous system is fragile. If you push a set to absolute ego-failure on a light day, tap the yellow bolt icon on the exercise card. The algorithm will remember your mistake and permanently drop the prescribed intensity by 1 RPE the following week to prevent central fatigue.
• SAR (Subjective Auto-Regulation) : Tap the SAR button on any exercise to rate your Pump and Soreness. The app listens to your body: if you are extremely sore with zero pump, it dynamically deletes sets next week. Huge pumps with no soreness? It adds sets!
• Mesocycle Fatigue Tracking 🔋: The top dashboard automatically tracks your progression through 4-6 week training blocks (Mesocycles). It visually displays your accumulating fatigue. When the meter hits Critical, you know a Deload or Intro week is imminent.
• Muscle Heatmaps 🔥: In the sidebar, open the Heatmap to visually scan your exact muscular recovery state. The app reads every set you've done this week and highlights whether your Chest is fresh, or if your Quads are completely destroyed.

Research-Backed Science Engine

Every feature in this app is validated by peer-reviewed exercise science. Here are the three intelligence systems running silently in the background:

• Volume Landmarks (Schoenfeld et al., 2017) 📊: Below the week banner, you'll see color-coded pills for each muscle group. These represent the exact set counts prescribed per week, mapped against published volume thresholds:
  • LOW — Below Minimum Effective Volume. You won't grow.
  • MEV — Minimum Effective Volume (floor for growth). Barely enough stimulus.
  • MAV — Maximum Adaptive Volume (the sweet spot). This is where most growth happens.
  • MRV! — Maximum Recoverable Volume (ceiling). Beyond this, you're overtraining and risking injury.

  Hover any pill to see exact thresholds. The study found each additional set/week = ~0.37% more hypertrophy, but with diminishing returns beyond 10+ sets.

• Progressive Overload Arrows (Goldberg et al., 1975) 📈: Once you log a set, look at the 1RM row on each exercise. You'll see a trend arrow comparing your current weight to 5 weeks ago (the previous mesocycle):
  • ⬆ Green — Progressing. Weight increased vs. last meso. Keep pushing.
  • ➡ Yellow — Maintaining. You're plateauing. Consider adding volume or switching exercises.
  • ⬇ Red — Regressing. Weight decreased. Possible overtraining, poor recovery, or missed sessions.

  Progressive overload is the #1 mechanism for muscle growth. If you aren't increasing load over time, you will plateau.

• Strength Standards (ExRx / Symmetric Strength) 🏋️: On compound lifts (Bench, Squat, Deadlift, OHP), you'll see a rank badge next to your estimated 1RM. This is calculated by dividing your 1RM by your bodyweight:
  • Beginner → Novice → Intermediate → Advanced → Elite

  Log your bodyweight in the "Morning Bodyweight" field to activate this system. Your rank is based on population-level strength data validated across thousands of lifters.

• Fatigue Interception (Auto-Deload) 🚨: The app scans your SAR soreness ratings and CNS overshoot flags from the previous week. If it detects critical fatigue (2+ CNS blowouts or 3+ extreme soreness ratings), it automatically intercepts the current week: sets are cut in half and RPE is capped at 6. A red pulsating banner warns you that recovery mode has been activated.

The 6 Phases (Classified Progression)

To prevent analysis paralysis, the future is heavily encrypted. You cannot skip the grind. You must check off your workouts to earn the right to see what comes next. Here is your roadmap:

Analytics & History

Open the View Strength Analytics panel from the sidebar to witness your entire journey rendered on a dual-axis chart. The algorithm seamlessly tracks your exact exercise history, even bridging the data across massive phase shifts (like Incline Press switching to OHP), while plotting your morning bodyweight on a secondary axis so you can mathematically prove your growth.
