Aerobic base
Steady work improves the ability to sustain effort and recover between harder bouts.

BUILD THE ENGINE
Conditioning should support life, sport and clear thinking. Build an aerobic base, add carefully dosed intensity and progress without turning every session into punishment.
Enter the system ↓01 / THE FOUNDATION
Steady work improves the ability to sustain effort and recover between harder bouts.
Intervals should resemble the demands of the activity: short power, repeated rounds or longer threshold work.
Conditioning is productive only when it can coexist with strength, skill, sleep and normal life.
WHO population guideline; scale to the individual.
Exercise is associated with better cognition and attention.
02 / THE PROTOCOL
Use the same sequence until good decisions become easier to reproduce under pressure.
Use walking, cycling, rowing or swimming at conversational effort.
Increase total weekly time gradually before adding more hard sessions.
Keep work and recovery repeatable. End before mechanics collapse.
Track how quickly breathing settles and how the next day feels.

FIELD CHECKLIST
01Can I speak in short sentences?
02What energy system am I training?
03Is this intensity necessary today?
04Will tomorrow’s quality suffer?
05What is the smallest useful progression?
FAILURE PATTERNS
×Turning every session into HIIT
×Adding running volume too fast
×Using exhaustion as proof
×Ignoring pain that changes mechanics
