Tennis Fitness¶
Train the Chain. Not the Muscles.
The Principle¶
Tennis fitness isn't general fitness. It's specific capacity for the Q-V-ROOT-8-45-Impulse-Jin chain.
Every exercise must answer: Does this improve my chain?
The Physical Demands of the Chain¶
| Variable | Physical Requirement | Training Focus |
|---|---|---|
| Q | Visual processing speed, focus endurance | Vision drills, cognitive load |
| V | Neck stability, vestibular tolerance | Neck isometrics, gaze stability |
| ROOT | Foot intrinsic strength, ankle stiffness, hip rotation | Barefoot work, single-leg, rotational power |
| F | Fascial elasticity, line continuity | Dynamic stretching, plyometrics, loaded carries |
| P | Proprioceptive acuity, spindle sensitivity | Unstable surfaces, eyes-closed, perturbation |
| T | Tensegrity integrity, no energy leaks | Core stiffness, anti-rotation, breathing |
| SSC | Elastic power, short amortization | Plyometrics, depth jumps, reactive hops |
| 8 | Coordinated continuous movement | Complex patterns, flow drills |
| 45° | Diagonal plane strength | Rotational med ball, cable chops |
| BRAKE | Eccentric strength, deceleration | Eccentric overload, landing control |
| PULSE | Rate of force development | Ballistic intent, minimal time |
| JIN | Whole-body elastic expression | Integrated patterns, variability |

| Fri | Strength + Chain Integration | Different patterns + upper chain + shadow |
| Sat | Match / Competition | Warmup only |
| Sun | Off | Mental visualization, light walk |
Off-Season Progression¶
| Phase | Weeks | Focus | Volume |
|---|---|---|---|
| Base | 1-4 | Structural balance, tendon prep, movement quality | 3×/week, moderate |
| Strength | 5-8 | Max strength in chain patterns | 3×/week, heavy |
| Power | 9-12 | Rate of force development, SSC | 3×/week, explosive |
