Calories burned during Strength training — 15 to 60 minutes
Strength training is estimated at about 3.5 METs. A 70 kg person may burn roughly 129 calories in 30 minutes or 257 calories in 60 minutes.
Calories by body weight
| Body weight | 30 minutes | 60 minutes |
|---|---|---|
| 60 kg | 110 kcal | 220 kcal |
| 70 kg | 129 kcal | 257 kcal |
| 80 kg | 147 kcal | 294 kcal |
| 90 kg | 165 kcal | 331 kcal |
Calories by duration for a 70 kg person
| Duration | Estimated calories |
|---|---|
| 15 minutes | 64 kcal |
| 30 minutes | 129 kcal |
| 45 minutes | 193 kcal |
| 60 minutes | 257 kcal |
What changes the calorie burn?
Strength sessions include rest between sets, so calorie burn is less predictable than continuous cardio. Their value also includes strength and muscle retention.
Two people with the same body weight can burn different amounts because movement efficiency, fitness, intensity and rest time differ. MET tables describe an average energy cost, not a laboratory measurement of your session.
How the estimate is calculated
For example, multiply the calories-per-minute estimate by 30 for a half-hour session. The result is rounded because false precision would make the number look more certain than it is.
How to use Strength training in a weight-management plan
- Choose a frequency you can repeat without excessive soreness or injury risk.
- Increase time, pace or resistance gradually rather than changing everything at once.
- Keep daily food intake in view; exercise calories are only one part of total energy balance.
- Include muscle-strengthening work on at least two days each week when appropriate for you.
- Use weekly trends in weight, waist and fitness—not one workout number—to judge progress.
Safety and recovery
Stop and seek medical advice for chest pain, fainting, severe breathlessness or a new injury. People who are pregnant, recently inactive, recovering from surgery or managing a medical condition may need an individualized starting plan.
Method and sources
Estimates use standard MET-based calculations. Public-health guidance generally encourages adults to accumulate regular aerobic activity and muscle-strengthening activity, while recognizing that some activity is better than none. See Sources & Methodology.
