Estimate calories burned during resistance band or strength training from your body weight and workout time, or find the time needed for a calorie target.
How the Resistance Band Workout Calorie Calculator Works
This calculator applies general resistance-training MET values as rough proxies for band workouts. The 2024 Adult Compendium lists 3.5 MET for multiple resistance exercises at 8–15 repetitions, 5.8 MET for circuit/reciprocal supersets/peripheral heart action training, and 6.0 MET for vigorous free-weight or machine resistance training. These categories do not specifically validate resistance-band expenditure.
Formula: gross kcal = MET x 3.5 x body weight in kg / 200 x minutes
What the Results Show
The workout modes estimate gross calories or the time required for a gross-calorie target. Gross includes resting expenditure. Above-rest calories subtract a standardized 1 MET baseline, rather than your measured resting rate. The mechanical-work mode separately calculates external pulling work in joules; its work-equivalent and assumption-scaled kcal are not measurements of calories burned.
Calculator-Specific Detail
Workout structure supplies the chosen MET proxy; band color or nominal tension does not map to a universal calorie rate. The separate mechanical scenario requires average pulling force over the entered distance. Work = average force × distance × repetitions. A nominal band rating alone cannot supply that average because force changes with stretch. The assumed multiplier of 5 corresponds to a hypothetical 20% external-work efficiency, with no claim of validation for resistance bands. The archived approximate foot-pound calculation remains available in calculation details for comparison.
Assumptions and Limitations
Use cumulative workout time that reasonably matches the selected structure, including only the rest pattern represented by that proxy. Band tension, range of motion and personal effort are not directly measured. The Adult Compendium is intended for ages 19–59; its group MET values do not predict precise individual expenditure. Technique, conditioning, rest, equipment and individual resting metabolism affect results. The oxygen equation assumes 3.5 mL O₂/kg/min per MET and 5 kcal/L O₂, which yields 1.05 kcal/kg/hour per MET. These are estimates rather than a personal exercise or nutrition prescription.
