HIIT - The Basics: Everything You Need to Know

Is HIIT better than running?

Whether HIIT or running is better depends on your goals, fitness level, and available time. Both forms of exercise offer unique benefits, but they differ significantly in intensity, impact, and long-term effects. In this article, we’ll explore how High-Intensity Interval Training (HIIT) compares to traditional steady-state running—and which might be the better choice for you.

What is HIIT?

HIIT, or High-Intensity Interval Training, involves short bursts of intense exercise followed by brief periods of rest or active recovery. A typical HIIT session lasts between 15 and 30 minutes and combines elements of cardio, strength, and agility training. The goal is to raise your heart rate quickly, push your body to its limits, and achieve maximum results in minimal time.

What does running offer?

Running—especially at a steady, moderate pace—is a classic endurance workout that strengthens the cardiovascular system and improves aerobic capacity. It’s also great for mental clarity and stress relief. Many people enjoy the meditative rhythm of running and the chance to be outdoors.

HIIT vs. Running: A direct comparison

• Calories burned: HIIT burns more calories per minute than jogging, and the afterburn effect (EPOC) means you keep burning calories even after your workout ends.
• Time efficiency: HIIT is ideal for busy schedules—a 20-minute HIIT session can match or exceed the benefits of 45 minutes of running.
• Muscle engagement: Running mainly targets the legs, while HIIT can activate the entire body and support muscle building, depending on the exercises used.
• Endurance: Running improves aerobic endurance over time. HIIT boosts anaerobic capacity and overall fitness, and can complement endurance training when combined.
• Joint impact: HIIT can be hard on the joints if done without proper form or rest. Running also carries risks—especially with high mileage or poor running surfaces.
• Variety & motivation: HIIT tends to offer more variety and excitement. Running is more repetitive, but easier to maintain as a long-term habit for many people.

Which is right for you?

If your goal is to burn fat quickly, improve overall fitness, and build strength, HIIT might be your best bet. You can do it anywhere, and it doesn’t require much time. If you’re aiming to build endurance, clear your mind, or enjoy being outside, running may be the better option. In fact, many people benefit from combining both—using HIIT on non-running days or incorporating intervals into their runs.

Conclusion

HIIT isn’t necessarily better than running—it depends on what you’re looking for. Both are powerful tools for improving health and fitness. For fast results and maximum efficiency, HIIT is hard to beat. For long-term endurance and mental well-being, running shines. The best workout is the one you enjoy and stick with consistently.
