One hour is the most common full weight training session length. It allows time for both a warm-up and multiple working sets across 4 to 6 exercises. The direct calorie output from one hour of vigorous lifting exceeds most 30-minute cardio sessions and approaches moderate running at 5 mph. Adding EPOC post-workout raises the 24-hour total further.
This article covers MET-based one-hour tables by body weight, watt-based intensity estimates, EPOC addition, and weight loss planning.
How Many Calories Does 1 Hour of Weight Training Burn?
The MET formula calculates one-hour output directly:
Calories = MET × body weight (kg) × 1 hour
The 2024 Adult Compendium assigns MET 3.5 to general free-weight training, MET 6.0 to vigorous weight training, and MET 8.0 to circuit training. For a 154 lb (70 kg) person at vigorous effort: 6.0 × 70 × 1 = 420 calories. At general effort: 3.5 × 70 × 1 = 245 calories.
For the full weight training hub covering all durations, EPOC data, and training vs cardio comparisons, see the calories burned weight training guide. For cross-activity comparisons, the calories burned guide places one hour of lifting alongside running, cycling, and HIIT.

1-Hour Weight Training at 150 Pounds
1-Hour Lifting Calories for a 150 lb Person
Format | MET | Calories / 1 Hour |
|---|---|---|
Light lifting | 3.0 | 204 kcal |
General free weights | 3.5 | 238 kcal |
Vigorous lifting | 6.0 | 408 kcal |
Circuit training | 8.0 | 544 kcal |
A 150 lb person at vigorous effort for one hour burns approximately 408 calories. Done five days per week, that produces approximately 2,040 calories of weekly exercise output. Adding estimated EPOC at 10% brings the weekly total to approximately 2,244 calories. Combined with a 200 calorie daily dietary reduction, five weekly vigorous one-hour sessions support approximately 1.21 lb of fat loss per week. This rate is sustainable for most adults without requiring extreme dietary restriction.
1-Hour Weight Training with EPOC: Total 24-Hour Calorie Impact
The true calorie impact of one hour of weight training extends beyond the session itself. EPOC adds post-workout calorie burn lasting 24 to 38 hours. Research from Sports Medicine (Børsheim and Bahr, 2003) found weight training EPOC magnitude of 6 to 15% above session calories.
1-Hour Weight Training: Session + EPOC (154 lb / 70 kg)
Intensity | Session Calories | EPOC (10% est.) | 24-Hour Total |
|---|---|---|---|
General (MET 3.5) | 245 kcal | +25 kcal | ~270 kcal |
Vigorous (MET 6.0) | 420 kcal | +42 kcal | ~462 kcal |
Circuit (MET 8.0) | 560 kcal | +56 kcal | ~616 kcal |
Including EPOC, one hour of vigorous weight training produces approximately 462 calories of 24-hour calorie impact for a 154 lb person. Circuit training with EPOC reaches approximately 616 calories per session. For a full breakdown of EPOC duration, magnitude by training volume, and how afterburn compares between lifting and cardio, see the weight training afterburn EPOC guide.
1-Hour Weight Training vs 1-Hour Cardio
One hour of vigorous weight training (MET 6.0) burns approximately 420 calories for a 154 lb person. Running at 5 mph (MET 8.3) burns approximately 581 calories in the same window. Running burns approximately 38% more per session hour.
However, weight training's EPOC advantage partially closes this gap over 24 hours. A vigorous one-hour lifting session adds approximately 42 calories of EPOC versus approximately 17 to 29 calories from a running session of the same duration. The 24-hour gap narrows from 161 calories to approximately 130 to 150 calories.
The long-term picture favours weight training further. Each kilogram of lean muscle added by consistent lifting raises resting metabolic rate by approximately 13 calories per day. Three kg of lean muscle gain over 6 months adds approximately 39 daily resting calories, or 273 per week, compounding fat loss indefinitely. For the complete session-by-session and long-term calorie comparison, see the weight training vs cardio guide.
1-Hour Weight Training Weight Loss Planning
Weekly Calorie Output from 1-Hour Weight Training (154 lb / 70 kg, Vigorous + EPOC)
Frequency | Per Session | EPOC est. | Weekly Total | Approx. Weekly Fat Loss |
|---|---|---|---|---|
3 × per week | 420 kcal | +42 kcal | 1,386 kcal | ~0.40 lb |
4 × per week | 420 kcal | +42 kcal | 1,848 kcal | ~0.53 lb |
5 × per week | 420 kcal | +42 kcal | 2,310 kcal | ~0.66 lb |
5 × per week + 300 kcal/day diet | 420 kcal | +42 kcal | 4,410 kcal | ~1.26 lb |
Five weekly vigorous one-hour sessions combined with a 300 calorie daily dietary reduction creates a weekly deficit of approximately 4,410 calories for a 154 lb person. This supports approximately 1.26 lb of fat loss per week.
For 30-minute session data with proportional output, see the calories burned weight training 30 minutes guide. Use the TDEE calculator to establish your maintenance calorie level before planning the weekly deficit.

Frequently Asked Questions About 1 Hour of Weight Training
How Many Calories Does 1 Hour of Weight Training Burn?
A 154 lb (70 kg) person burns approximately 210 to 560 calories in one hour of weight training. Light lifting (MET 3.0) produces approximately 210 calories. General free-weight training (MET 3.5) produces approximately 245 calories. Vigorous lifting (MET 6.0) produces approximately 420 calories. Circuit training (MET 8.0) reaches approximately 560 calories per hour.
How Many Calories Does 1 Hour of Lifting Burn at 150 Pounds?
A 150 lb (68 kg) person burns approximately 204 to 544 calories in one hour of weight training. At general effort (MET 3.5), output is approximately 238 calories. At vigorous effort (MET 6.0), it rises to approximately 408 calories. Circuit training (MET 8.0) produces approximately 544 calories per hour.
Is 1 Hour of Weight Training Enough to Lose Weight?
Five weekly vigorous one-hour sessions burn approximately 2,310 calories per week including estimated EPOC for a 154 lb person. Combined with a 300 calorie daily dietary reduction, that supports approximately 1.26 lb of fat loss per week. Research from Westcott (2012) confirmed that 10 weeks of resistance training produced 1.8 kg of fat loss without dietary change, confirming the fat-loss effectiveness of consistent weight training.
How Many Calories Does a Female Burn Lifting Weights for 1 Hour?
A woman's calorie burn in one hour of weight training depends on her body weight. A 130 lb woman doing vigorous lifting burns approximately 354 calories per hour. A 150 lb woman burns approximately 408 calories. A 170 lb woman burns approximately 462 calories per hour at MET 6.0 vigorous effort. These figures are identical to male estimates at the same body weight because the MET formula is sex-neutral and scales purely by body mass at equivalent relative effort.
Does Lifting Heavy Burn More Calories in 1 Hour Than Lifting Light?
Lifting heavy loads (85 to 95% of one-rep max) burns more calories per active set than lifting light. However, heavy training requires longer rest periods (3 to 5 minutes) that reduce per-hour calorie output compared to moderate-load training with shorter rests. Vigorous moderate-load training at 60 to 75% of one-rep max with 30 to 45 second rests (MET 6.0) typically burns more calories per hour than maximal-load training with long rests despite the lower absolute weight. For maximum per-hour calorie output, moderate weight with minimal rest periods is more effective than maximum load with long rest periods.
How Does 1 Hour of Weight Training Build Muscle and Burn Fat Simultaneously?
One hour of vigorous weight training creates a direct calorie deficit from session output and EPOC. Simultaneously, the mechanical stimulus of resistance training activates muscle protein synthesis (MPS), promoting lean mass accrual over recovery days. This dual effect — burning calories during the session and building calorie-consuming muscle tissue in the days after — makes weight training unique among fat-loss activities. Each kilogram of new lean muscle adds approximately 13 daily resting calories. Gaining 3 kg of lean mass from 6 months of consistent one-hour sessions adds approximately 273 weekly resting calories, compounding fat loss indefinitely beyond session outputs. This is a calorie advantage that no steady-state cardio format can replicate over the same training period.
