How Many Kilojoules Are You Burning?

Ever wondered which activities actually burn the most kilojoules, and why exercise matters so much for weight loss? Spoiler: it’s not just about what happens during the workout itself.

Let’s break it down in a way that feels simple, motivating, and totally doable.

🔥 Why Exercise Matters (Beyond the Kilojoules)

Yes, you burn energy while you’re exercising, but the real magic happens after your workout.

  • When you exercise regularly, you increase your muscle percentage.
  • Muscle cells use fat as their preferred energy source.
  • So the more muscle you have, the more fat your body burns — even while you’re resting, reading, or sipping your morning coffee.

This is why strength training is such a powerful partner to cardio. It turns your body into a 24-hour fat‑burning machine.

📊 How Many Kilojoules Do You Burn?

(For a 70 kg person)

These numbers are approximate, but they give you a great sense of how different activities compare:

ActivitykJ per hourkJ per minute
HIIT (High Intensity Interval Training)378063
Skipping310052
Jogging @ 9 km/h300050
Swimming @ 45 m/min200033
Brisk walking @ 7.5 km/h180030
Cycling @ 20 km/h170028
Tennis (singles)170028

👉 Remember: The more you weigh, the more kilojoules you burn doing the same activity. A 50 kg person will burn less; an 80 kg person will burn more.

🎯 Your Weight‑Loss Goal: What It Takes

To lose ½ kg per week, you need to burn roughly 15 000 kJ more than usual.

You can do this by:

  • Increasing the duration of your workouts
  • Increasing the intensity
  • Adding strength training to boost your resting metabolism
  • Mixing up your routine to keep your body guessing (and your mind excited!)

💪 Variety = Better Results

For the best weight‑loss results, your weekly plan should include:

  • Cardio (walking, jogging, cycling, swimming)
  • Strength training (to build fat‑burning muscle)
  • HIIT (for maximum burn in minimum time)

Strength training is especially powerful because your body continues burning fat long after you’ve finished your session.
