Think of it like car engines: Aerobic is your efficient long-distance diesel engine. Anaerobic is your Formula 1 engine—incredibly powerful but guzzles fuel fast and can't run at max for long.

Practical signs: If you're breathing hard but steady and could keep going for 30 minutes it's aerobic. If you're gasping for air and have to stop after 30 seconds it's anaerobic. Your heart rate is also a clue: aerobic typically keeps you in 70-85% of your max heart rate while anaerobic pushes you to 85-100%. You need both! Aerobic exercise helps your body recover better from anaerobic sessions by improving circulation. And anaerobic exercise (like strength training) helps preserve muscle mass which keeps your metabolism higher even at rest. Don't choose one—do both for complete health.
