Weight Lifting Calorie Calculator | MET-Based Estimates
Weight training is one of the most effective ways to build muscle and burn calories. Unlike cardio, strength training has a significant afterburn effect (EPOC) that keeps your metabolism elevated long after your workout ends. This calculator uses MET (Metabolic Equivalent of Task) values from the ACSM to estimate calories burned during weight lifting sessions.
Whether you're doing bodyweight exercises, machine training, or heavy barbell lifts, knowing your calorie burn helps you track progress and plan your nutrition accordingly.

Calculation Examples
Example 1 �?45-Minute Free Weight Training
Weight = 180 lbs (81.6 kg), Duration = 45 min, MET = 5.0
Calories = 5.0 × 81.6 × 0.75 = 306 calories
EPOC (20%) = 61 calories
Total = 367 calories
Calories = 5.0 × 81.6 × 0.75 = 306 calories
EPOC (20%) = 61 calories
Total = 367 calories
Example 2 �?30-Minute Circuit Training
Weight = 150 lbs (68.0 kg), Duration = 30 min, MET = 6.0
Calories = 6.0 × 68.0 × 0.50 = 204 calories
EPOC (25%) = 51 calories
Total = 255 calories
Calories = 6.0 × 68.0 × 0.50 = 204 calories
EPOC (25%) = 51 calories
Total = 255 calories

MET Values for Weight Training
The following MET values are based on ACSM guidelines for different types of weight training:
| Exercise Type | MET Value | Description | EPOC Contribution |
|---|---|---|---|
| Light Resistance Training | 3.5-4.0 | High reps, low weight | 10-15% |
| Bodyweight Exercises | 3.0-4.5 | Push-ups, squats, planks | 10-20% |
| Machine Weight Training | 4.0-5.0 | Selectorized machines | 15-20% |
| Free Weight Training | 5.0-6.0 | Barbells, dumbbells | 15-25% |
| Circuit Training | 5.5-7.0 | Continuous, limited rest | 20-25% |
| Heavy Weight Training | 6.0-8.0 | Low reps, heavy weight | 20-30% |
Calorie Burn by Weight and Duration
| Body Weight | 30 min (MET 5.0) | 45 min (MET 5.0) | 60 min (MET 5.0) |
|---|---|---|---|
| 120 lbs (54.4 kg) | 163 calories | 245 calories | 327 calories |
| 150 lbs (68.0 kg) | 204 calories | 306 calories | 408 calories |
| 180 lbs (81.6 kg) | 245 calories | 367 calories | 490 calories |
| 200 lbs (90.7 kg) | 272 calories | 408 calories | 544 calories |
| 220 lbs (99.8 kg) | 300 calories | 450 calories | 600 calories |
Key Considerations
- EPOC: Strength training creates greater EPOC than steady-state cardio
- Intensity: Higher intensity = higher MET = more calories per minute
- Muscle Mass: More muscle = higher resting metabolism = more calories at rest
- Rest Periods: Shorter rest increases effective workout intensity
- Form: Proper form ensures muscle engagement and calorie burn

Frequently Asked Questions
-
Weight lifting calories are calculated using MET (Metabolic Equivalent of Task) values. The formula is: Calories = MET × Weight (kg) × Duration (hours). Different exercises have different MET values based on intensity.
-
MET values for weight lifting range from 3.5 (light resistance) to 8.0 (heavy weight training). Bodyweight exercises typically range from 3.0 (calisthenics) to 6.0 (circuit training), according to ACSM guidelines.
-
Yes, lifting heavier weights with lower reps typically burns more calories per minute due to higher intensity. However, total calorie burn also depends on duration. Higher intensity training may have a larger post-workout calorie burn (EPOC).
-
EPOC is the extra oxygen consumption that occurs after exercise to restore the body to its pre-exercise state. For weight training, EPOC can contribute an additional 15-25% of calories burned during the workout, depending on intensity and duration.
