Episode notes
Mediterranean Spearfishing Challenges
- The Mediterranean has intense fishing pressure and fewer fish species compared to other regions.
- Continuous fishing and poor management reduce fish size and abundance, making spearfishing more challenging.
Smart Training Trumps Punishment
- Consistent, moderate freediving training leads to sustainable improvement without unnecessary strain.
- Quality and frequency trump punishing, infrequent training sessions for better adaptation.
Swimming Training Basics
- Combine long relaxed swims with shorter fast laps and breathing pattern variations for effective swimming training.
- Incorporate breath-holding sets like pyramids to improve CO2 tolerance and efficiency.
