Weightlifting Calories Burned Calculator
Use this Weightlifting Calories Burned Calculator to estimate the energy used during a lifting session from your bodyweight, session time and the type of resistance training you performed.
Choose the activity description that best matches both the lifting and rest periods in your session. The result uses a published MET value and stays an estimate; it does not claim exact calories per repetition.
You’ll get total session calories, calories above your resting baseline and a duration comparison you can save, copy, share or print.
Your Weightlifting Calorie Estimate
Your selected result is either total session energy or energy above rest. The result card also shows the other value so you can tell whether the resting baseline is included.
Save the activity category, bodyweight and duration with the estimate when you want to compare sessions using the same convention.
Calculate above to see your result and the numbers behind it.
Describe the Session You Performed
Enter bodyweight and the full session duration, including the rest periods described by the activity category. Choose free weights, squat/deadlift training, mixed lifting or circuits based on the best available match.
The category choice matters more than the name of one exercise. A session with long rests should not be treated as continuous circuit training.
- Weight unit
- Choose the unit shown on your weights.
- Bodyweight
- Enter your current bodyweight, without any extra exercise weight.
- Workout duration
- Enter how many minutes the selected activity lasted.
- Workout style
- Choose the description that best matches this part of your workout.
Supported weight-training activities
Choose the row that best describes the whole timed session, including its rest pattern. The calculator uses the matching 2024 Adult Compendium MET value.
| Activity code | Workout description | MET |
|---|---|---|
| 02050 | Vigorous resistance training with free weights or machines | 6 |
| 02052 | Squats or deadlifts performed slowly or explosively | 5 |
| 02054 | Several exercises with varied weights for 8–15 reps | 3.5 |
| 02055 | Resistance circuits, reciprocal supersets or peripheral heart action | 5.8 |
Compare Calories by Session Length
The duration chart shows total calories and calories above rest for the same bodyweight and activity choice. It helps you see how the estimate changes with time without implying that every minute is identical.
The table includes the resting baseline so gross and net values cannot be confused.

| Gross energy | 22.5 | 105 | Estimate |
| Gross energy | 30 | 140 | Estimate |
| Above-rest energy | 0 | 0 | Estimate |

| Above-rest energy | 22.5 | 75 | Estimate |
| Above-rest energy | 30 | 100 | Estimate |
How Lifting Calories Are Estimated
Gross calories use the selected MET × bodyweight in kilograms × time in hours. Above-rest calories subtract one MET for the energy you would have used during that time at rest.
The calculator uses the 2024 Adult Compendium activity values and exact unit conversion. It does not use repetitions, bar weight or heart-rate data.

| Result | Value | Type |
|---|---|---|
| Gross Kcal | MET * bodyweightKg * durationMinutes / 60 | Equation |
| Net Above Rest Kcal | (MET - 1) * bodyweightKg * durationMinutes / 60 | Equation |
A 30-Minute Lifting Example
This checked example uses pounds. It comes directly from the same calculator that produces your result.
Select “Use example” to load these values. If you choose kilograms in the calculator, the chart and personalized tables recalculate in kilograms.
| Result | Value |
|---|---|
| Weight unit | lb |
| Bodyweight | 176.37 lb |
| Workout duration | 30 |
| Workout style | Several exercises with varied weights for 8–15 reps |
| Estimated gross energy | 140 kcal |
| Gross energy | 140 kcal |
| Resting baseline energy | 40 kcal |
| Above-rest energy | 100 kcal |
| Selected activity MET | 3.5 MET |
Why the Estimate Can Differ
MET values describe groups and activity categories, so individual technique, work-to-rest ratio and physiology can change actual energy use. Treat a small difference between sessions as an estimate, not a measured change.
