Episode notes
Conditioning With Loaded Carries
- Use loaded carries (sandbags, yoke, farmer carries) for conditioning with short intervals to build sport-specific work capacity.
- Progress rounds gradually (e.g., 10 → 12 → 15 rounds every minute) to avoid overreach.
Hydration And Intra-Workout Nutrition
- Use intra-workout carbs, electrolytes, aminos, and creatine during long sessions to maintain performance.
- Prioritize hydration and potassium (coconut water) for acute performance gains.
Grip Reflects Neural Readiness
- Grip strength correlates with neural readiness and can act as a fatigue indicator.
- A drop in grip can signal neural fatigue; good grip numbers often indicate readiness.
