Conclusion: Which is Best for Fat Loss?

Both workouts have their advantages. HIIT is excellent for maximizing calorie burn in a short period, while strength training builds muscle, which can increase your resting metabolic rate over time. If you’re looking for a quick, intense session, the 20-minute HIIT is your go-to. However, if you have slightly more time and want to build strength, the 30-minute strength training is ideal.

Next Steps

Consider your schedule and fitness goals. If you're aiming for more fat loss, incorporate both styles into your weekly routine. Aim for three sessions of HIIT and two of strength training per week for optimal results.
