How Plank Test Results Are Calculated
The plank test is a simple assessment of core muscular endurance. Your score is determined by how long you can hold a proper plank position. This calculator compares your hold time to age- and gender-adjusted norms to determine your percentile and fitness category. Core endurance is an important component of overall fitness, spinal health, and athletic performance.
The normative values used in this calculator are derived from population-level data on plank test performance. The average hold time declines with age and differs between men and women, so the calculator adjusts for both factors to give you a meaningful percentile ranking within your demographic group.
The Calculation Method
Average (Male) = 90 − Age × 0.5
Average (Female) = 70 − Age × 0.4
Percentile = (Hold Time ÷ Average) × 50
Percentile is clamped between 0 and 100 for comparison
Hold time is measured in seconds
Formula Source
This calculator uses **plank test norms** adapted from the **American College of Sports Medicine (ACSM) Guidelines for Exercise Testing and Prescription** and the **Canadian Physical Activity, Fitness & Lifestyle Approach (CPAFLA)** protocols.

Worked Example
A 30-year-old male who holds a plank for 90 seconds. Average for his age and gender = 90 − (30 × 0.5) = 75 seconds. Percentile = (90 ÷ 75) × 50 = 60th percentile. This places him in the "Good" category — above average for his age. A 30-year-old female holding the same 90 seconds would have a higher percentile because the female average for her age is lower: 70 − (30 × 0.4) = 58 seconds, giving a percentile of 78th — "Excellent."
FAQ-Style Explanations
What is a good plank time? For most adults, holding a plank for 60–90 seconds is considered average. A 2-minute plank is good, and 3+ minutes is excellent. Beyond 2 minutes, the benefits of longer holds diminish, and adding variations becomes more productive.
Why do women tend to score higher on the plank test? Research suggests that women have slightly better relative core endurance than men, possibly due to differences in muscle fiber type distribution and body composition. The norms used in this calculator reflect this difference.
Does plank performance correlate with overall fitness? Core endurance is one component of fitness, but a high plank score does not guarantee overall fitness. It specifically measures the endurance of your trunk stabilizers, not cardiovascular fitness, upper body strength, or lower body power.
Known Limitations
- The normative data is drawn from general population studies and may not be representative of athletes, older adults, or specific ethnic groups.
- Plank hold time is effort-dependent. A person who is not motivated to push to their limit will score lower than their true capacity.
- Proper form is essential for a valid test. A sagging hip or raised buttocks reduces the challenge and invalidates the comparison to norms.

Standard Plank Calorie Burn
The standard forearm plank has a MET value of 2.0-2.5, making it a light-to-moderate intensity isometric exercise. The calories burned per minute using the MET formula are calculated as MET × body weight in kg ÷ 60. At 2.5 MET, a 50 kg person burns approximately 2.08 calories per minute, a 70 kg person burns about 2.92 calories per minute, and a 90 kg person burns roughly 3.75 calories per minute. These figures show that even at moderate MET values, the per-minute calorie burn from a standard plank remains relatively modest compared to dynamic exercises like jogging (MET 7.0) or cycling (MET 8.0).
- 50 kg at 2.5 MET: approximately 2.08 calories per minute
- 70 kg at 2.5 MET: approximately 2.92 calories per minute
- 90 kg at 2.5 MET: approximately 3.75 calories per minute
Side Plank and Dynamic Variation Calories
Side planks and dynamic plank variations significantly increase the metabolic demand and calorie burn per minute. A side plank raises the MET value to 3.0-3.5 because it recruits the obliques more intensely and challenges lateral stability. A plank with alternating arm raises pushes the MET to 3.5-4.0 as the shoulder muscles and upper back work harder to maintain balance with one arm raised. Plank jacks, which add a jumping component to the plank position, reach MET values of 5.0-6.0, making them genuinely vigorous cardio exercise. A dragon flag, an advanced variation popularized by Bruce Lee, can reach MET values of 6.0-7.0 and burns calories at a rate comparable to moderate jogging.
The MET Formula Explained
The MET (Metabolic Equivalent of Task) formula provides a standardized way to estimate calorie expenditure for any activity. One MET equals the energy cost of sitting quietly, which is approximately 1 kilocalorie per kilogram of body weight per hour. To calculate calories burned per minute for any activity, multiply the MET value by your body weight in kilograms, then divide by 60. For example, a 70 kg person doing a side plank at 3.5 MET burns 3.5 × 70 ÷ 60 = 4.08 calories per minute. This formula works for any activity with a known MET value, from walking to weightlifting to swimming, making it a versatile tool for estimating energy expenditure across all forms of exercise.
Detailed Calorie Burn Table by Intensity
The table below shows calorie burn per minute at different plank intensities for three common body weights. These figures are calculated using the mid-point MET value for each variation and the standard MET formula. Higher intensity plank variations can meaningfully increase calorie burn, though they should be approached with proper form to avoid injury. For reference, a 30-minute session of plank jacks at 5.5 MET burns approximately 96 calories for a 70 kg person, compared to 88 calories for a 30-minute session of standard planks at 2.5 MET—roughly a 10% increase for substantially more cardiovascular demand.
- Standard plank (2.5 MET): 70 kg burns ~2.9 cal/min
- Side plank (3.25 MET): 70 kg burns ~3.8 cal/min
- Plank with arm raises (3.75 MET): 70 kg burns ~4.4 cal/min
- Plank jacks (5.5 MET): 70 kg burns ~6.4 cal/min
- Dragon flag (6.5 MET): 70 kg burns ~7.6 cal/min
FAQ
Frequently Asked Questions
A standard forearm plank at 2.5 MET burns approximately 2.1 calories/min at 50 kg, 2.9 cal/min at 70 kg, and 3.75 cal/min at 90 kg.
The formula is: calories per minute = MET value × body weight in kg ÷ 60. For example, 2.5 MET × 70 kg ÷ 60 = 2.92 calories per minute.
A side plank at 3.0-3.5 MET burns approximately 3.5-4.1 calories per minute for a 70 kg person, about 25% more than a standard plank.
Yes, plank jacks at 5.0-6.0 MET burn roughly 5.8-7.0 calories per minute for a 70 kg person, nearly double the burn of a standard plank.
A dragon flag is an advanced plank variation where you lift your entire body off the ground using only your upper back. At MET 6.0-7.0, it burns approximately 7.0-8.2 calories per minute for a 70 kg person.
