Conclusion: Which Burns More Fat?

While both workouts can contribute to fat loss, the HIIT workout is designed for maximum calorie burn in a short period, making it ideal for those with limited time. On the other hand, strength training promotes muscle growth, which can lead to increased resting metabolism over time.

For best results, consider incorporating both styles into your weekly routine. Aim for 3 sessions of each type per week, allowing for recovery days in between.

Next Steps:

• Try a 20-minute HIIT session on one day, followed by a 45-minute strength workout on another.
• Monitor your progress and adjust your routine based on your goals.
