Does lifting weights burn more calories than cardio?

When it comes to managing weight and improving health, many of us wonder: does lifting weights burn more calories than cardio? The answer depends on several factors, including exercise intensity, duration, body size and composition, and your long-term goals. Below, we review the latest evidence from credible sources and help you decide which approach—or combination—may work best for you.

How calorie burn is measured

Before comparing lifting and cardio, it’s helpful to understand how we estimate calories burned:

• Metabolic equivalents (METs): A way to compare the energy cost of different activities. 1 MET is the energy you burn at rest.
• Direct measurement: Lab tests (e.g., indirect calorimetry) measure oxygen consumption for precise results.
• Estimates from fitness tools: Wearables and online calculators use your age, weight, heart rate and activity type to estimate calories burned.

Credible organizations such as Harvard Health Publishing and the American College of Sports Medicine (ACSM) provide MET tables you can use as a reference.

Calorie burn during exercise

Cardio (aerobic exercise)

Activities like running, cycling, rowing and swimming generally burn more calories per minute than weightlifting. For example, Harvard Health Publishing estimates that a 155-lb person burns approximately:

• Running at 5 mph: ~ 600 calories/hour
• Cycling (moderate, 12–13.9 mph): ~ 560 calories/hour
• Rowing (moderate effort): ~ 520 calories/hour

Lifting weights (resistance training)

Traditional weightlifting sessions typically burn fewer calories during the workout itself. For the same 155-lb individual:

• Light/moderate effort (general strength training): ~ 220 calories/hour
• Vigorous effort (circuit training with weights, minimal rest): ~ 440 calories/hour

(Source: Harvard Health Publishing, “Calories burned in 30 minutes for people of three different weights.”)

Key takeaway: If you compare only the calories burned during a 60-minute session, steady-state cardio usually wins.

The afterburn effect: EPOC

Excess post-exercise oxygen consumption (EPOC), often called the “afterburn,” is how many calories you burn above resting levels while your body recovers. Studies show:

• Heavy resistance training (e.g., squats, deadlifts) can boost EPOC by 6–15% above calorie burn during exercise.
• Intense cardio (e.g., high-intensity interval training, HIIT) also increases EPOC, but resistance training tends to have a longer afterburn.

According to the ACSM’s Health & Fitness Journal, a tough lifting session can raise your metabolic rate for up to 24 hours, whereas moderate steady-state cardio often returns you to baseline faster.

Long-term effects on resting metabolism

One of the biggest advantages of lifting weights is its impact on lean muscle mass. More muscle means:

• A higher resting metabolic rate (RMR): Each pound of muscle burns roughly 6–10 calories per day at rest, whereas fat burns about 2 calories.
• Improved body composition: Shifting the muscle-to-fat ratio supports better long-term weight management.

In contrast, steady-state cardio builds endurance but has a smaller effect on muscle growth. That doesn’t mean cardio isn’t valuable—it improves cardiovascular health, lung capacity, and mood.

Comparing overall calorie burn

When you consider both exercise and resting metabolism, resistance training can rival or even exceed steady-state cardio in total daily calorie burn—especially if you lift heavy, keep rest periods short, and train multiple muscle groups. A balanced program might look like:

• 3 days of resistance training (full-body or split routines)
• 2–3 days of cardio (mix steady-state and interval workouts)

This approach leverages the high calorie burn of cardio during workouts and the muscle-building, metabolic boost from lifting.

Practical tips for maximizing calorie burn

Whether you lean toward weights or cardio, you can optimize each session:

• For lifting weights:
– Use compound movements (squats, bench press, rows) that work multiple joints.
– Keep rest periods to 30–60 seconds for circuit-style sessions.
– Progressively increase weight or reps over time.

• For cardio:
– Incorporate intervals (e.g., 30 sec sprint, 1 min walk) to raise heart rate quickly.
– Vary your activities (running, cycling, rowing, jumping rope) to challenge different muscles.
– Aim for at least 150 minutes of moderate or 75 minutes of vigorous activity weekly, per WHO guidelines.

Which is right for you?

• If your primary goal is to burn the most calories during a workout, steady-state cardio or high-intensity interval training (HIIT) may be best.
• If you want to boost your resting metabolic rate and improve strength and body composition, prioritize resistance training.
• For overall health, blend both: cardio for heart and lung health; lifting for bones and muscles.

Safety and when to check in with a doctor

Before starting or drastically changing your exercise routine, consider:

• Personal health conditions (e.g., heart disease, joint issues, uncontrolled high blood pressure)
• Current fitness level and injury history
• Medications that affect heart rate or metabolism

If you experience concerning symptoms—chest pain, dizziness, severe joint pain or unusual shortness of breath—stop exercising and consult a professional. You might also try a free, online symptom check, using the doctor approved Ubie Symptom Checker to help you decide if you need prompt medical attention.

Always speak to a doctor about anything that could be life-threatening or serious. Your healthcare provider can offer personalized advice and may recommend diagnostics or supervised programs when needed.

Putting it all together

In summary:

• Does lifting weights burn more calories than cardio?

  • During exercise: cardio typically burns more calories per minute.
  • After exercise: resistance training often creates a larger “afterburn” and builds muscle, increasing your daily calorie needs.
  • Long-term: more muscle mass leads to a higher resting metabolic rate, which supports weight management.

• Best approach: Combine cardio and strength training to maximize calorie burn, improve health markers and enjoy a varied routine.

By understanding how each modality affects calorie expenditure—immediately and over time—you can tailor a fitness plan that suits your goals, schedule and preferences. Remember, consistency matters more than perfection. Start where you are, track your progress, and adjust as you get stronger and fitter.
