Planking is a fantastic low-impact isometric exercise that builds core strength and endurance, but it doesn't burn calories the way walking or running does. This calculator helps you estimate the calories burned while planking for the time it would take to walk a mile — a fun way to compare the energy cost of a static hold against a classic distance-based activity.
Simply enter your weight, the duration of your plank hold, and your walking pace. The tool converts your plank time into an equivalent "distance" and estimates the calories burned, using the standard MET (Metabolic Equivalent of Task) value for planking. It's perfect for fitness enthusiasts, yoga practitioners, and anyone curious about how their core work stacks up in calorie terms.
Use the quick-fill buttons to try common scenarios, or adjust the inputs to match your own routine. The result includes a step-by-step breakdown so you can see exactly how the estimate is calculated.

How to Use This Tool
Enter your body weight, the duration of your plank hold, and your typical walking pace (the time it takes you to walk one mile). The calculator then estimates the calories burned during that plank session and expresses it as an equivalent "calories per mile" figure — essentially, how many calories you'd burn per mile if planking were a distance activity.
You can switch between kilograms and pounds, and between seconds and minutes for the plank duration. The walking pace can be entered in minutes per mile or hours per mile. Use the quick-fill buttons to load common scenarios, then adjust the values to match your own routine.
Formula Explained
The calculation uses the standard MET (Metabolic Equivalent of Task) method. Planking has a MET value of approximately 3.8, meaning it burns about 3.8 times the energy you'd burn at rest. The formula is:
Calories per minute = MET × 3.5 × weight (kg) / 200
This gives the calories burned per minute. Multiply by your plank duration (in minutes) to get total calories. To find the equivalent distance, divide your plank duration by your walking pace (in minutes per mile). Finally, divide total calories by the equivalent distance to get calories per mile.
Worked Examples
Example 1: A 70 kg person holds a plank for 60 seconds (1 minute) and walks at a pace of 20 minutes per mile.
Calories per minute = 3.8 × 3.5 × 70 / 200 = 4.655 kcal/min
Total calories = 4.655 × 1 = 4.7 kcal
Equivalent distance = 1 / 20 = 0.05 miles
Calories per mile = 4.7 / 0.05 = 93.1 kcal/mile
Example 2: A 155 lb person (about 70.3 kg) holds a plank for 2 minutes and walks at a pace of 15 minutes per mile.
Calories per minute = 3.8 × 3.5 × 70.3 / 200 = 4.67 kcal/min
Total calories = 4.67 × 2 = 9.3 kcal
Equivalent distance = 2 / 15 = 0.133 miles
Calories per mile = 9.3 / 0.133 = 70.0 kcal/mile
Tips & Best Practices
- Planking is primarily a strength and endurance exercise, not a calorie-burning workout. Use this calculator for curiosity and comparison, not as a weight-loss metric.
- To increase calorie burn, you can add variations like side planks, plank with leg lifts, or increase the hold time gradually.
- Always maintain proper form: keep your body in a straight line from head to heels, engage your core, and avoid sagging or arching your back.
- Combine planking with aerobic activities like walking or cycling for a balanced fitness routine.
Factors Affecting Accuracy
The MET value for planking can vary based on intensity. A relaxed plank might be closer to 3.0 METs, while a very intense hold with added movements could reach 4.5 METs. Your individual metabolism, muscle mass, and fitness level also influence actual calorie burn. This calculator provides a reasonable estimate, but for precise numbers, consider using a heart rate monitor or a fitness tracker.
Frequently Asked Questions
Why does planking burn so few calories compared to walking?
Planking is an isometric exercise, meaning your muscles contract without changing length. While it builds strength and endurance, it doesn't require the same cardiovascular effort as dynamic activities like walking or running, which involve large muscle groups moving your body weight over distance.
Can I use this calculator for other isometric exercises?
Yes, you can approximate for exercises like wall sits or static holds, but the MET value will differ. For wall sits, a MET value of around 2.8 is often used. Adjust the MET in the formula if you want a more accurate estimate.
How does this compare to walking a mile?
Walking a mile typically burns about 80-100 calories for a 150 lb person, depending on pace. Planking for the time it takes to walk a mile (e.g., 20 minutes) would burn roughly 90-100 calories, but that's a very long plank hold — most people can't hold a plank for 20 minutes!
Is planking good for weight loss?
Planking alone is not very effective for weight loss due to its low calorie burn. However, it's excellent for building core strength, which can improve your performance in other exercises and daily activities. Combine it with aerobic exercise and a healthy diet for best results.
