Weight lifting and calories burned: How many calories does lifting weights burn for men?

Most men burn roughly 200 to 600 calories in a 45 minute lifting session depending on body weight, the MET level of the workout (traditional lifting around 3.5 METs vs vigorous circuits around 8 METs), and how dense the session is (rest times and transitions). Compared with a steady cardio session of the same length, many men still burn fewer calories during the lift itself. The real win is that smart programming can raise your workout’s intensity, protect muscle during fat loss, and add a small “afterburn” effect that supports long term body recomposition.

Key takeaways

• According to the 2011 Compendium of Physical Activities, a typical strength workout done for sets of 8 to 15 reps is about 3.5 METs, while vigorous circuit training can reach about 8 METs, meaning much higher calorie burn for the same time.^[1]
• Research summarized in Sports Medicine suggests that after a “typical” strength workout, excess post exercise oxygen consumption often lasts about 1 hour and averages about 35 extra calories burned, which helps but will not replace a calorie deficit.
• A small 2008 study found that a very high volume, eccentric emphasized full body session produced an unusually large, multi day rise in energy expenditure (reported as roughly 550 calories over 72 hours), but this is an aggressive protocol with high soreness and recovery demands and it should not be assumed to occur after normal lifting sessions.^[3]
• Research published in Medicine and Science in Sports and Exercise supports that progressive resistance training can increase resting metabolic rate by about 5 percent on average in some men, mainly by supporting lean mass.^[2]
• A 2021 systematic review found that resistance circuit based training can improve body composition and fitness while saving time, which is useful when your goal is weight loss with limited gym hours.

Why weight lifting and calories burned matter for men

Weight lifting and calories burned are linked in a straightforward way. The harder your body works to move load, stabilize joints, and recover between sets, the more energy it spends. But if you are asking, “how many calories does lifting weights burn,” the most accurate answer is that it depends on your body size and how you structure the session.

According to the 2011 Compendium of Physical Activities, a “general” strength training session is often categorized around 3.5 METs.^[1] MET stands for metabolic equivalent of task, which is a way to express how hard an activity is compared with resting quietly. That same Compendium lists higher values for more vigorous, more continuous styles of lifting, especially when the workout starts to resemble cardio because rest periods shrink.^[1]

For men, this matters because fat loss is usually limited by total weekly energy balance, not by any single workout. If traditional lifting feels “slow” because of long rest periods, the calorie burn can be modest. But you still want resistance training in your plan because it helps you maintain lean mass during weight loss, and leaning out while keeping muscle is the look most men are after.^[6]

How lifting weights burns calories

your body size sets the baseline

According to the Compendium of Physical Activities, MET values let you estimate relative effort, but total calories burned still scale with body mass because moving a larger body and stabilizing heavier segments costs more energy.^[1] This is one reason two men can do the same session and get very different numbers on a tracker.

If you want a practical estimate, use a calculator that accepts METs, body weight, and time, then compare sessions. The goal is not a perfect number. The goal is a repeatable way to see whether today’s “weights session” was closer to a low intensity strength day or a high output conditioning day.

intensity is not only the weight on the bar

In strength coaching, intensity often means how heavy the load is relative to your max. But for calorie burn, intensity also means how continuously you are working. According to the Compendium, a typical weights session with multiple exercises and moderate rest is about 3.5 METs, explosive or more demanding lifting can be around 5 METs, and vigorous circuit training with minimal rest can reach about 8 METs.^[1]

Circuit training is a format where you move exercise to exercise with short transitions. This keeps your heart rate higher, drives breathing, and makes weight lifting and calories burned look more like a hybrid of strength and cardio. The tradeoff is that you will not lift your heaviest weights in this format because fatigue accumulates faster.

the afterburn effect exists, but it is usually small

Excess post exercise oxygen consumption is the period after training when your body uses extra oxygen to recover. EPOC means your system is paying back the metabolic “loan” from hard work. According to a 2014 study in the Journal of Strength and Conditioning Research, resistance training and high intensity intervals can create more EPOC than steady state cardio when workouts are matched for calories burned during the session.

Still, the size of that afterburn is easy to overhype. Research summarized in Sports Medicine reports that after a typical strength workout, EPOC often lasts about an hour and averages about 35 extra calories burned. That helps, but it does not “erase” a weekend of overeating.

eccentric training can increase calorie burn after lifting, with a recovery cost

Eccentric contraction is the lowering phase of a lift, like lowering a squat or lowering a dumbbell curl. It can cause more muscle damage and soreness because it loads muscle fibers while they lengthen. A 2008 study in the Journal of Strength and Conditioning Research reported that a single, very high volume full body session with an eccentric emphasis increased post exercise energy expenditure for up to 72 hours, averaging about 550 additional calories burned across that window.^[3]

It is important to interpret that finding as a high volume outlier, not the expected result of normal training. Most lifting sessions produce EPOC in the range of tens of calories, not hundreds, and individual response varies widely with training status, total volume, and how close you train to failure.

That approach is not for every man. The same mechanism that increases energy cost can also increase delayed onset muscle soreness, which can wreck the rest of your training week. A 2010 study found a more conservative option. One set with a slower four second eccentric produced a similar multi day rise in energy expenditure, around 300 additional calories over 72 hours, while reducing total volume.^[4]

muscle supports resting metabolism, but do not expect miracles

Basal metabolic rate is the calories your body burns at rest to keep you alive. Lean mass is everything in your body that is not fat, including muscle. According to research published in Medicine and Science in Sports and Exercise, progressive resistance training can increase resting metabolic rate by about 5 percent on average in some adults, likely because it helps build or preserve lean mass.^[2]

The realistic take for most men is this. Strength training can help your “background burn,” but it is not a free pass. Your nutrition still drives whether you lose fat. Think of muscle as making your plan easier to sustain, not as a loophole.

Clinical note for men: If fat loss is unusually hard despite consistent training, sleep, and a calorie deficit, it can be reasonable to talk with a clinician about evaluation for medical or hormonal factors. The Endocrine Society and American Urological Association recommend diagnosing testosterone deficiency only in men with consistent symptoms plus repeatedly low morning testosterone on reliable testing, and then doing further lab work to evaluate the cause (for example, primary vs secondary hypogonadism). Only a clinician can diagnose hypogonadism; confirm abnormal results with repeat morning labs and symptom review before considering treatment.^[9],[10]

Health issues tied to low activity and low muscle mass in men

Weight lifting and calories burned are not only about abs. For many men, strength training is part of preventing a slow slide into low fitness, chronic pain, and metabolic risk as the decades stack up.

Here are clinical situations where the calories you burn lifting weights and the muscle you keep can matter.

• Overweight and obesity: According to a 2022 systematic review and meta analysis, resistance training in people with overweight and obesity improves body composition outcomes across the lifespan, which supports fat loss efforts when paired with nutrition changes.^[6]
• Loss of lean mass during dieting: When men diet aggressively, it is common to lose some lean mass along with fat. Resistance training is a key tool to bias weight loss toward fat rather than muscle, especially when combined with adequate protein intake.^[6]
• Time constrained lifestyle: If your barrier is time, circuit based lifting can be a practical compromise. A 2021 systematic review found that resistance circuit based training improves strength and cardiorespiratory fitness while supporting body composition changes, in less time than traditional longer sessions.

Limitations note: Most calorie burn numbers in weight lifting come from lab estimates or averages. Your real total depends on exercise technique, rest periods, how close you train to failure, and even how much you fidget between sets. Wearables can be useful for trends, but they often struggle with resistance training because heart rate is an imperfect proxy for lifting workload.

Signals your lifting plan is not burning what you think

If your main goal is fat loss, “how many calories does lifting weights burn” is only useful if your program matches your goal. These signs suggest your session may be too low output to move the needle, or too aggressive to recover from.

• You finish most workouts feeling like you could repeat the whole session immediately, and your breathing never picks up.
• Your lifting sessions are dominated by long rest periods, and total “work time” is low compared with time on your phone.
• You only do isolation lifts, and you rarely train big movement patterns like squats, rows, presses, lunges, and loaded carries.
• Your weight and waist size have been stable for 4 to 6 weeks, and your daily steps and diet have not changed.
• You try eccentric focused training often, and you stay sore for several days, which reduces weekly training quality.
• You rely on a watch estimate as a license to eat more, even though your weekly trend is not moving.
• You feel persistently run down and your performance is dropping week to week, which can mean recovery is not keeping up.

Why these signals matter: if your breathing never rises and rest times dominate, your session’s average MET level is likely closer to “general lifting” than a higher output circuit, so calorie burn will be on the lower end. If you avoid compound patterns, you may be missing the biggest “bang for your buck” movements that recruit more muscle at once. If your weight trend is flat for weeks, the issue is usually weekly energy balance (food intake, steps, and training density), not a single “bad” workout. And if soreness or fatigue keeps you from training hard 2 to 4 times per week, your total weekly work can drop, which lowers both calorie burn and progress. Troubleshoot by tightening rest periods, prioritizing compound lifts, tracking weekly averages (not single sessions), and dialing back eccentric emphasis or total volume when recovery stalls.

What to do to burn more calories while lifting weights

Here is a simple, evidence based way to get more out of weight lifting and calories burned without turning every session into a sloppy cardio class.

1. Step 1: estimate your true output and pick the right target. Use a MET based calculator to estimate calories burned for your body weight and training style. Track weekly trends, not single workouts. If you are trying to lose fat, set your plan around a consistent calorie deficit from nutrition and activity, then use lifting to protect muscle and improve performance. If symptoms suggest an underlying medical or hormonal issue (for example, persistently low libido, erectile dysfunction, loss of morning erections, unexplained low energy, or unusually poor recovery), talk with a clinician for evaluation. Diagnosis of testosterone deficiency requires symptom review plus repeat morning testing, and further labs may be needed to determine the cause before any treatment decisions are made.^[9],[10]
2. Step 2: redesign your lifting session for higher calorie burn. According to a 2011 study in the Journal of Strength and Conditioning Research, lifting lighter weight for more reps can substantially increase energy expenditure compared with heavy, low rep work when total time is similar.^[7] For most men focused on fat loss, use mostly compound lifts and keep the session moving. Practical targets:
   • Choose 4 compound exercises per circuit. Examples include squat pattern, hinge pattern, horizontal push, horizontal pull.
   • Use a load that lands around 15 to 30 reps close to failure. Stop when you feel you only have 1 to 2 good reps left.
   • Keep transitions to about 15 to 20 seconds. Rest longer only if your form breaks.
   • Repeat the circuit 3 to 5 rounds, then switch to a new circuit if time allows.

   Loading note: According to a 2021 Sports Medicine review on resistance training loading, higher reps with moderate loads can still build muscle when sets are taken close to failure, as long as the load is not too light to be challenging. A 2020 meta analysis also found that low load and high load resistance training can produce similar muscle hypertrophy when effort is matched, which matters for men who worry that “lighter” work will kill gains.^[8]

3. Step 3: use “afterburn” tactics strategically, then recover and monitor. If you want to experiment with EPOC, add short blocks that increase density, such as short rest circuits or brief finishers. If you use eccentric emphasis, do it sparingly. Research published in the Journal of Strength and Conditioning Research shows that very high volume eccentric work can meaningfully increase post exercise energy expenditure in some settings, but it can also increase soreness and recovery time, and results may not generalize to typical workouts.^[3] A more conservative option is one set with a controlled four second lowering phase, which also increased energy expenditure over several days in one study.^[4] Monitor soreness, sleep, and performance. If your lifts stall and you feel chronically beat up, your calorie burn may actually fall because training quality drops.

Myth vs fact

• Myth: Lifting weights does not burn enough calories to matter.
  Fact: Weight lifting burns calories during the session and can add a small afterburn. It also helps preserve lean mass, which supports better long term body composition.^[2],[6]
• Myth: The heaviest weights always burn the most calories.
  Fact: For calorie burn, workout density matters. Shorter rest periods and circuit formats can push METs much higher than traditional heavy lifting with long rests.^[1]
• Myth: EPOC means you burn hundreds of calories after every lift.
  Fact: Most typical strength sessions produce a modest afterburn, often around 35 calories over about an hour. High volume eccentric training can be larger, but it is not the norm and it costs recovery.^,[3]
• Myth: Circuit training is only cardio and will not build muscle.
  Fact: A 2021 systematic review found that resistance circuit based training can improve strength and body composition, especially for men prioritizing fat loss with limited time.
• Myth: Doing cardio means you should skip weights if you want to lose fat.
  Fact: A prospective cohort study found that combining resistance exercise with aerobic exercise is linked with better obesity related outcomes than aerobic training alone, likely because you burn more total calories while protecting muscle.^[5]

Bottom line

Most men burn about 200 to 300 calories in 45 minutes of traditional lifting with longer rests (around 3 to 5 METs), and about 400 to 650 calories in the same time with a dense circuit style session (around 8 METs). Your exact number depends mainly on body weight, exercise selection, and how much rest you take, so use the estimate to compare sessions and manage weekly energy balance.
