Chapter 5: Fitness Bootcamp
Swimming Conditioning Regimen
- **Current Resistance Training:**
4hrs/day @ 0.8 m/sec → builds tail muscles
- **Interval Training:**
2 min sprint / 5 min recovery → 8 cycles
- **Oxygen Efficiency:**
93% DO saturation → simulates high-altitude training Body Sculpting Techniques:
- Concave Belly Prevention: Feeding in vertical current
- Dorsal Fin Alignment: Dorsal fin massage therapy
- Final Trim: 14-day fast pre-transport
Chapter 6: Pre-Show Logistics Warfare
72-Hour Transport Protocol
1. **Tank Specifications:**
- Black polyethylene with foam insulation
- O2 tank + battery backup
2. **Water Chemistry:**
- Home pond water 80%
- New RO water 20%
- Ammonia binder @ 5ppm
