Sample Answer

Continuous aerobic training

Sustained moderate-intensity exercise (60-75% MHR)
Extended periods without rest (20+ minutes)
Typically 30-60 minutes total duration
Predominantly aerobic energy system

HIIT:

Alternates high-intensity periods (85-95% MHR) with recovery
Varied work-to-rest ratios
Shorter total duration (15-30 minutes)
More intense overall
Engages both aerobic and anaerobic systems
