Five minutes of planking instead of an hour of running is one of the most common fitness myths. But what does science say? Does static exercise replace intense cardio? Let's find out who's right. The plank is excellent for strengthening the core, shoulders, and glutes. A 70-kilogram person burns about 2-5 calories per minute of planking. This increases muscular endurance but does not replace aerobic exercise. Running, at an average speed of 10 km/h, burns up to 700 calories per hour for the same person. It strengthens the cardiovascular system and lungs and develops overall endurance. These are different types of exercise. Research from the American Council on Exercise (ACE) shows that planks build strength, while running builds cardio endurance. It's like comparing apples and oranges. You can't simply "swap" one for the other; their goals are different. So, the myth is debunked. Five minutes of planking burns 10-25 calories, while an hour of running burns up to 700. For overall health, incorporate both static exercises and cardio. Your body will thank you for the integrated approach!
