Estimate calories burned holding a plank from your body weight and hold time using the 2.8 MET plank value, or find how long to plank for a calorie target.
Plank Hold Calories Formula
Variables:
- PC = modeled gross active-hold energy (kcal) under the supplied factor
- BW = body weight in pounds for this factor-based equation
- T = total active-hold time (minutes), excluding rest
- F = assumed gross activity factor (kcal/lb/min)
There is no fixed factor established here for every standard, knee, side or weighted plank. The 2024 Adult Compendium’s light-effort calisthenics category includes plank at 2.8 MET. The calculator uses gross kcal = MET × 3.5 × kg × active minutes / 200. A supplied gross factor converts as MET = F / (0.0175 × 0.45359237); the 2.8-MET reference corresponds algebraically to F ≈ 0.02222602613 kcal/lb/min. Above-rest energy instead uses MET − 1, an assumed resting baseline rather than an individual measurement.
How to Calculate Plank Hold Calories
- Enter body weight in pounds, kilograms or stone; the calculator converts the quantity when units change.
- For session calories, enter active minutes and additional seconds per set, then the exact whole number of sets. Optional rest contributes only to session clock time.
- Choose the disclosed 2.8-MET activity reference, a custom MET assumption or a custom gross kcal/lb/min factor, then select gross or above-rest energy.
- Select Calculate. Reverse-duration mode divides the calorie target by the selected energy rate; comparison mode applies supplied MET assumptions to the same weight and active time.
Example
As a conditional arithmetic example, a 220 lb person enters 5 total active minutes and a custom gross factor F = 0.0302 kcal/lb/min. That supplied factor is about 3.80455 MET; it is not a validated universal standard-plank rate.
Illustrative Gross Calories (kcal) at Assumed F = 0.0302
| Body Weight | 1 Minute | 5 Minutes | 10 Minutes |
|---|---|---|---|
| 100 lbs | 3.0 | 15.1 | 30.2 |
| 150 lbs | 4.5 | 22.7 | 45.3 |
| 200 lbs | 6.0 | 30.2 | 60.4 |
| 250 lbs | 7.6 | 37.8 | 75.5 |
FAQs
How many calories does a 1-minute plank burn?
Under the broad 2.8-MET light-calisthenics assumption, the gross estimate is about 3.33 kcal for a 150 lb person or 4.45 kcal for a 200 lb person over 1 active minute. These are model outputs, not measured individual plank expenditure.
Do side planks burn more than standard planks?
Plank style alone does not establish a calorie rate. Technique, effort, load and individual physiology matter; this calculator does not assign unsupported fixed side- or weighted-plank coefficients.
Should I use basic or advanced mode?
Choose session calories for active holds and sets, active time for a calorie target for reverse solving, or intensity comparison for up to four supplied MET assumptions. A positive above-rest target has no finite solution at the modeled 1-MET resting rate. Duration estimates are arithmetic, not an exercise prescription.
Does body weight change the result a lot?
At the same MET assumption and active duration, this model scales energy directly with body mass. That relationship does not establish how much two individuals actually expend; standard MET and resting-rate assumptions can differ from personal physiology.
