How Many Calories Do I Burn While Lifting Weights?

On average, a 155-pound (70 kg) person burns between 220 and 440 calories per hour of weight lifting, depending on intensity, muscle mass, and workout structure. Heavier individuals or those performing high-intensity resistance training can burn up to 500+ calories per hour.

Factors That Influence Calorie Burn During Weight Training

Calorie expenditure during strength training isn't fixed—it varies significantly based on multiple physiological and mechanical factors. Understanding these helps optimize workouts for fat loss or performance.

Exercise Intensity and Volume

Training Experience and Efficiency

Calories Burned by Weight Class and Workout Type

The following table provides estimated calorie burn per 30 minutes of weight lifting based on body weight and effort level.

Body Weight Light Effort (cal/30 min) Moderate Effort (cal/30 min) Vigorous Effort (cal/30 min)
125 lbs (57 kg) 90 120 180
155 lbs (70 kg) 112 150 223
185 lbs (84 kg) 133 178 266
215 lbs (98 kg) 156 208 311
Table data source:1, 2

Data shows that calorie burn scales linearly with body weight. For example, a 215-pound individual burns approximately 25% more than a 155-pound person at the same intensity. Vigorous lifting nearly doubles calorie expenditure compared to light effort, highlighting the importance of intensity in maximizing energy output.

Afterburn Effect: EPOC and Long-Term Calorie Burn

Unlike steady-state cardio, weight lifting triggers Excess Post-Exercise Oxygen Consumption (EPOC), meaning you continue burning calories after your workout.

This “afterburn” effect makes weight lifting highly effective for long-term fat loss, even if session burn seems moderate.

Frequently Asked Questions About Calories Burned Lifting Weights

Does lifting weights burn more calories than cardio?

During the workout, moderate cardio like running typically burns more calories than standard weight lifting. However, when factoring in EPOC and muscle gain, lifting weights can lead to greater long-term fat loss and metabolic rate increases.

How many calories do I burn in a 1-hour weights session?

A 155-pound person burns approximately 220–450 calories in an hour of weight training, depending on intensity. Vigorous, full-body lifting with minimal rest can exceed 500 calories, especially for heavier individuals.

Do heavier weights burn more calories?

Yes—lifting heavier weights recruits more muscle fibers and demands more energy both during and after exercise. However, maintaining proper form and avoiding injury is crucial when increasing load.

Can I lose belly fat by lifting weights?

You cannot spot-reduce fat, but weight lifting builds muscle, boosts metabolism, and reduces overall body fat—including visceral abdominal fat. Combined with diet, it’s highly effective for reducing belly fat over time.

Is 30 minutes of weight lifting enough to burn significant calories?

Yes—30 minutes of intense, compound-based lifting can burn 200–300 calories and trigger substantial EPOC. Shorter, high-effort sessions are effective for improving body composition and metabolic health.
