Track the energy cost of a short, focused block of barbell pulls. This calculator estimates how many calories you burn during a five-minute deadlift session using your body weight, the weight on the bar, the number of reps you complete, and the intensity of your effort. It applies the standard metabolic equivalent (MET) method with the widely used ACSM energy expenditure equation, so the result stays consistent with other exercise calorie estimates.
Strength training often gets overlooked in calorie tracking because it burns less per minute than steady-state cardio — but every working set counts. The calculator returns a five-minute total and a per-minute rate, then adds a bonus breakdown of the mechanical work you performed: total tonnage moved, mechanical energy in kilojoules, and the work-equivalent calories of lifting the bar itself.
Built for lifters logging training sessions, coaches estimating workout energy cost, and anyone curious how a short deadlift block fits into their daily movement, this calculator keeps the math transparent and the inputs simple.

How to Use This Calculator
Enter your body weight and the barbell load — bar plus plates — using either kilograms or pounds; the two unit selectors let you mix unit systems if you prefer. Then enter the total number of reps completed within the five-minute window and choose the intensity that best matches the session: light warm-up pulls, controlled submaximal work, vigorous sets around 70–85% of your 1RM, or very heavy near-maximal singles.
The quick-fill buttons ("Warm-up 3×10", "Working 5×5", "Heavy singles") load realistic rep and intensity combos instantly, but the calculator accepts any values you choose. Press Calculate to see your five-minute calorie total, the per-minute rate, and a mechanical-work breakdown showing total tonnage moved, mechanical energy in kilojoules, and the work-equivalent calories of the barbell itself.
The Formula Behind the Estimate
This calculator uses the standard metabolic equivalent (MET) approach and the ACSM energy expenditure equation. One MET is the rate of energy use while sitting at rest — approximately 1 kcal per kilogram of body weight per hour. The energy cost of an activity is expressed as its MET value, and the commonly used equation is:
For the intensity levels in the selector, we use MET values from the Compendium of Physical Activities: 3.5 METs for light-to-moderate weight lifting, 6.0 METs for vigorous resistance training, and 8.0 METs for very heavy circuit-style or near-maximal lifting. Because the equation includes body weight, a heavier lifter burns more calories performing the same pulling work with the same bar speed and rest pattern.
The barbell work breakdown is a separate, purely mechanical calculation. Each rep is assumed to lift the load a nominal 0.5 m, so total mechanical energy = load (kg) × 9.81 × 0.5 m × reps. We convert joules to kilocalories (1 kcal = 4,184 J) to display the "work-equivalent" — the bare physical energy required to move the bar, before the body's inefficiency is added. It is informational context, not an alternative or additional calorie estimate.
For the underlying reference data, see the Compendium of Physical Activities or the American College of Sports Medicine resources.
Worked Examples
kcal/min = 6 × 3.5 × 75 ÷ 200 = 7.9 kcal/min → about 39 kcal in five minutes.
Mechanical work: 100 × 9.81 × 0.5 × 25 = 12,263 J ≈ 12.3 kJ ≈ 2.9 kcal work-equivalent, moving 2.5 tonnes of total load.
kcal/min = 8 × 3.5 × 90 ÷ 200 = 12.6 kcal/min → about 63 kcal in five minutes.
The heavier body weight and higher intensity roughly double the estimate of Example 1 despite far fewer reps — body mass and effort level matter more than tonnage in short blocks.
Factors That Affect Accuracy
MET-based estimates are population averages, and real energy cost varies with lifting technique, bar speed, rest between sets, and neuromuscular efficiency. A 5×5 block with 45-second rests is different from 25 touch-and-go reps in three minutes, even when the selected MET value is the same. The calculator assumes the five minutes are mostly occupied by lifting and short rest periods; if you spend long stretches setting up or chatting between sets, the true average intensity will be lower than your selected MET value.
For the most consistent comparisons between workouts, use the same intensity category and the same unit system each time. If your session mixes warm-ups and heavy work, pick the category that reflects the majority of the five minutes rather than the hardest single set.
Reference: MET Values for Strength Training
The table below lists Compendium MET codes commonly used for strength work. The deadlift has no dedicated code, so the intensity selector maps your session to the closest category.
| Activity | MET value | Used in this tool as |
|---|---|---|
| Weight lifting, light or moderate effort | 3.5 | Light warm-up sets |
| Resistance training, vigorous effort | 6.0 | Vigorous working sets |
| Power lifting, vigorous effort | 6.0 | Vigorous working sets |
| Circuit training, vigorous | 8.0 | Very heavy singles |
Note that 8.0 METs sits at the upper end of strength-training estimates. Very heavy deadlifting with long recovery periods between singles may average lower across the full five minutes, so when in doubt, choose the more conservative intensity.
Frequently Asked Questions
Why does body weight change the result? MET is defined relative to body mass, so the ACSM equation scales energy cost with the lifter's weight. Pulling a 100 kg bar involves more relative effort for a 60 kg lifter than for a 110 kg lifter, and the heavier lifter also expends more energy to stabilise and support their own body under load.
How accurate is the 0.5 m bar path? The calorie estimate does not rely on it — the bar path is used only for the informational mechanical-work breakdown. Actual bar travel depends on your height, hip and limb proportions, and lockout style, so treat the joules and work-equivalent figures as a rough illustration. Sumo pullers typically use a shorter path and conventional pullers a longer one in practice.
Can I compare this with estimates for other lifts? Yes — the same MET logic applies across barbell exercises. If you also squat, the squat MET calculator uses an identical method, and the static hold calorie calculator covers isometric work such as long pauses and plank holds.
Why doesn't this match my fitness watch? Wrist devices estimate intensity from heart rate and movement, while this calculator uses population-average MET values for the activity type. Differences are completely normal, and the MET estimate is usually the more consistent reference for planning and logging purposes.
