How Many Calories Do You Burn Lifting Weights?
Cardio gets all the glory for calorie burning, but a solid lifting session quietly burns a few hundred calories — plus it builds the muscle that raises your burn rate every day after. The trick is estimating your session's burn honestly, and the tool for that is a 30-second formula from exercise science called MET. Skip the guesswork and get a personalized number with our calories burned calculator — or read on to learn the formula itself and see the numbers for your body weight.
The Formula: Calories = MET × Weight × Time
Exercise scientists rate activities using METs — metabolic equivalents. One MET is the energy you burn sitting still. Lifting weights is assigned a MET value based on effort, and your calorie burn follows a simple equation:
Calories burned = MET × your weight in kg × hours exercised
Example: a 160 lb (72.6 kg) person lifting at moderate effort (5.0 MET) for 45 minutes (0.75 h): 5.0 × 72.6 × 0.75 = 272 calories.
The three MET tiers used for weight lifting, consistent with the Compendium of Physical Activities:
- Light effort — 3.5 MET: machine circuits with easy loads, long rests, slow pace. You could hold a conversation easily.
- Moderate effort — 5.0 MET: free-weight work at a steady pace, 1–2 minutes of rest between sets. You are breathing harder but not gasping.
- Vigorous effort — 6.0 MET: heavy compound lifts, supersets, or circuit-style training with short rests. You are sweating and need recovery between sets.
Calories Burned Lifting Weights: 30-Minute Chart
Every cell below was computed with the formula above for a 30-minute session. Find your weight, find your effort level, read your burn:
| Body weight | Light (3.5 MET) | Moderate (5.0 MET) | Vigorous (6.0 MET) |
|---|
| 130 lb (59 kg) | 103 | 147 | 177 |
| 160 lb (73 kg) | 127 | 181 | 218 |
| 190 lb (86 kg) | 151 | 215 | 259 |
| 220 lb (100 kg) | 175 | 249 | 299 |
Double the numbers for an hour-long session (the formula is linear in time). So a 190 lb lifter doing an hour of moderate free-weight work burns roughly 431 calories (215 × 2) — before the afterburn bonus described below.
Why These Numbers Are Estimates (But Good Ones)
The MET method is the best validated way to estimate lifting burn without lab equipment, but it has honest limitations worth knowing:
- Rest periods blur effort tiers. A session that mixes 2-minute scrolling-on-phone rests with heavy sets averages out to "moderate" even if the sets themselves were brutal. Be honest about your average pace when picking a tier.
- Muscle mass matters. Two 180 lb lifters at the same MET tier do not burn exactly the same — the one with more muscle tends to burn slightly more. The chart is a solid middle estimate.
- Fitness trackers often overread lifting. Watches and chest straps can inflate weight-room burn because elevated heart rate during rest periods looks like continuous work. MET math is usually the more conservative — and more accurate — number.
- EPOC adds a little extra. After intense lifting, your body burns additional calories repairing muscle and restoring oxygen — excess post-exercise oxygen consumption, or "afterburn." For a typical session it adds roughly 6–15% on top of the table numbers, spread over several hours. It is real, but it is not the 30–50% some influencers claim.
Compound vs Isolation: Does Exercise Choice Matter?
Within the same effort tier, yes — but not as much as the tier itself. Compound lifts (squats, deadlifts, bench press, rows, overhead press) recruit large muscle groups across multiple joints, so they push a session toward the vigorous end of your tier. Isolation work (bicep curls, triceps pushdowns, lateral raises) uses less total muscle, sitting toward the lighter end.
A practical example: two 40-minute sessions for a 160 lb lifter, both "moderate effort":
- Session A — squats, deadlifts, rows, overhead press (mostly compounds): lands near the top of the moderate tier, roughly 240–260 calories, plus the biggest EPOC bonus.
- Session B — curls, pushdowns, calf raises, lateral raises (mostly isolation): lands near the bottom of moderate, roughly 200–220 calories, with a smaller afterburn.
The compounds also build more muscle per session — and every pound of muscle you add raises your resting burn by a few calories a day, every day. That long-term effect is arguably worth more than the session numbers themselves.

Bottom Line
Expect 100–300 calories per 30 minutes of lifting depending on your size and effort. Use MET × weight (kg) × hours for a personalized estimate, lean on compound lifts for the bigger burn, and remember the real prize: muscle that raises your daily burn permanently.
Frequently Asked Questions
Roughly 100 to 300 calories depending on body weight and effort. For example, a 160 lb (73 kg) person burns about 127 calories at light effort, 181 at moderate effort, or 218 at vigorous effort in 30 minutes, per the MET formula.
Calories = MET × your weight in kilograms × hours exercised. One MET is your resting burn rate. Weight lifting is rated 3.5 MET (light), 5.0 MET (moderate), or 6.0 MET (vigorous). To convert pounds to kilograms, divide by 2.205.
Per minute, running usually burns more. A moderate run (8.0 MET) burns roughly twice what moderate lifting (5.0 MET) burns in the same time. But lifting adds muscle, which raises your resting calorie burn permanently — an advantage cardio does not match. The best strategy for fat loss is both, not either/or.
Yes. Exercises that use more muscle mass across multiple joints — squats, deadlifts, rows, presses — burn more than single-joint moves like curls or pushdowns. The difference mostly shows up as your session shifting to a higher average effort tier, plus a larger EPOC afterburn afterward.
EPOC — excess post-exercise oxygen consumption — is the extra calorie burn in the hours after intense exercise while your body repairs muscle and restores energy. For a typical lifting session it adds roughly 6–15% on top of the session's burn. It is real but much smaller than the dramatic claims on social media.
Yes, provided your diet is on target — fat loss comes down to a calorie deficit, and lifting both contributes calories burned and preserves muscle during the deficit. People who lift while dieting keep more muscle (and a higher metabolism) than people who only do cardio. Pair lifting with adequate protein, roughly 0.7–1 g per lb of body weight daily.
Trackers commonly overestimate lifting burn because they read your elevated heart rate during rest periods as continuous exercise. The MET formula, which averages the whole session including rests, is generally the more accurate estimate for resistance training. Use trackers for trends, not exact numbers.
