Training doesn’t make you fitter. Recovery does.
This isn’t a catchphrase — it’s backed by decades of research.
🧠 The science:
Your fitness improves after the session
During sleep, rest, and proper fueling
Not while you’re hammering reps or smashing intervals

1. Training is a stressor
It breaks the body down:
• Muscle damage
• Glycogen depletion
• Cortisol spikes
• Reduced capacity

2. Adaptation happens during recovery
Your gains happen when you stop and recover:
• Protein synthesis
• Nervous system reset
• Hormonal balance
• Mitochondrial growth

3. Poor recovery = stalled progress
No recovery means no adaptation:
• Fatigue builds
• Progress stops
• Burnout creeps in

Training is the stimulus. Recovery is the adaptation.
Ignore it, and you just stay tired. Respect it, and you actually get better.
