Types of Cardio

Not all cardio is created equal.

  • LISS: Low-intensity steady state (walking, easy cycling)
  • MISS: Moderate intensity (jogging, swimming)
  • HIIT: High-intensity interval training
  • Beginners should start with LISS and MISS

Starting Guidelines

Build gradually to prevent burnout.

  • Week 1-2: 10-15 minutes, 3x per week
  • Week 3-4: 15-20 minutes, 3x per week
  • Week 5-6: 20-30 minutes, 3-4x per week
  • Add 5 minutes or one session per week maximum

Heart Rate Zones

Training at appropriate intensity.

  • Zone 2 (60-70% max HR): Conversational pace, fat burning
  • Zone 3 (70-80% max HR): Challenging but sustainable
  • Zone 4-5 (80%+): Reserved for intervals, advanced

Pro Tip

The talk test: If you cannot hold a conversation, you are going too hard for steady cardio.

Choosing Your Activity

Pick something you will actually do.

  • Walking: Zero barrier to entry
  • Cycling: Low impact, scalable intensity
  • Swimming: Joint-friendly, full body
  • Rowing: Strength and cardio combined
  • Dancing: Fun and effective

Conclusion

Start with low-intensity cardio you enjoy. Build duration before intensity. Consistent easy cardio beats sporadic hard cardio.
