Start Here¶
New to the system? Start with these three steps.
Step 1: Understand the Map¶
The entire system is built on 12 variables that form one chain:
Read: The CORE Map →
Step 2: Find Your Broken Link¶
Every stroke error traces to one broken variable. The diagnostic takes 5 minutes.
Take: The CORE Diagnostic →
| Your Symptom | Likely Broken Link |
|---|---|
| Late contact, shanks | Q (Quiet Eye) |
| Head moves, balance off | V (Vestibular) |
| No power, falling back | ROOT (Rooting) |
| Arm-only swing, elbow pain | F/P (Fascia/Proprioception) |
| Muscled swing, no whip | T/SSC (Tensegrity/SSC) |
| Big takeback, late contact | 8 (Figure-8) |
| Flat balls, no margin | 45° (Swing Plane) |
| No penetration, pushy | BRAKE/PULSE |
| Inconsistent under pressure | JIN |
Step 3: Follow the Path¶
| Your Starting Point | Your Path |
|---|---|
| Recreational / Club | CORE Map → Diagnostics → Forehand Push → Serve/Return |
| Competitive / Tournament | Diagnostics → Your weakest variable → That variable's chapter → Drills |
| Coach / Teacher | CORE Map → Visual Library → Drills Library → AI Coach integration |
| High Performance | Full system → Variable deep-dives → Pattern training → Mental/Physical |
The Three Rules¶
- No variable works alone. The chain is only as strong as its weakest link.
- Don't skip links. You cannot fix PULSE if ROOT is broken.
- Train the chain, not the parts. Every drill connects to the full chain.
Your First Week¶
| Day | Focus | Action |
|---|---|---|
| 1 | The Map | Read CORE Overview — understand all 12 variables |
| 2 | Diagnose | Take CORE Diagnostic — find your broken link |
| 3 | The Fix | Read that variable's chapter — understand the biomechanics |
| 4 | Drill | Do the variable's key drill — 20 mins on court |
| 5 | Integrate | Shadow swings + Figure-8 drill — feel the chain |
| 6 | Play | Play points — use Pre-Point Routine on every point |
| 7 | Review | Film 5 forehands/backhands — compare to Visual Library |

The Philosophy¶
"The court doesn't lie. The ball doesn't care about your intentions. It only responds to physics. This system makes physics work for you."
