Conclusion

Both 20-minute full body strength training and 30-minute cardio workouts have their merits in fat burning. Strength training builds muscle, which can increase your resting metabolic rate, while cardio can burn more calories in a shorter burst.

If you’re looking for a shorter, more efficient workout, the strength training session is a solid choice. However, if you're aiming for maximum calorie burn and have the time, the cardio workout may suit you better.

Next Steps

Consider your schedule and preferences to determine which workout aligns best with your goals. You can also alternate between both types of workouts throughout the week to maximize your fat loss journey.
