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:

Q β†’ V β†’ ROOT β†’ F β†’ P β†’ T β†’ SSC β†’ 8 β†’ 45Β° β†’ BRAKE β†’ PULSE β†’ JIN

Read: The CORE Map β†’

Every stroke error traces to one broken variable. The diagnostic takes 5 minutes.

Take: The CORE Diagnostic β†’

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 45Β° (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 β†’ Diagnostics β†’ Forehand Push β†’ Serve/Return
Competitive / Tournament Diagnostics β†’ Your weakest variable β†’ That variable's chapter β†’ Drills
Coach / Teacher CORE Map β†’ Visual Library β†’ Drills Library β†’ AI Coach integration
High Performance Full system β†’ Variable deep-dives β†’ Pattern training β†’ Mental/Physical

The Three Rules

  1. No variable works alone. The chain is only as strong as its weakest link.
  2. Don't skip links. You cannot fix PULSE if ROOT is broken.
  3. 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 β€” understand all 12 variables
2 Diagnose Take CORE Diagnostic β€” find your broken link
3 The Fix Read that variable's chapter β€” understand the biomechanics
4 Drill Do the variable's key drill β€” 20 mins on court
5 Integrate Shadow swings + Figure-8 drill β€” feel the chain
6 Play Play points β€” use Pre-Point Routine on every point
7 Review Film 5 forehands/backhands β€” 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."
