how many calories does weight lifting burn
Weight lifting typically burns about 90–250 calories per 30 minutes for most people, depending heavily on your body weight and how hard you train.
How Many Calories Does Weight Lifting Burn?
Quick Scoop
Think of weight lifting as a “slow burn” workout: it may not torch as many calories per minute as intense cardio, but it works your muscles, boosts metabolism, and keeps burning energy even after you rack the weights.
Typical calorie ranges
These are rough ranges for a 30–60 minute session of general weight training:
- 30 minutes, light–moderate effort: about 90–150 calories.
- 30 minutes, more intense lifting: about 150–250 calories.
- 60 minutes, light–moderate: about 200–300 calories.
- 60 minutes, heavy/intense: about 350–500+ calories for larger individuals.
For many people around 155 lb (70 kg), general weight lifting comes out to roughly 100–150 calories per 30 minutes in typical studies and fitness references.
What Changes Your Calorie Burn?
Several levers control how many calories weight lifting burns in practice:
- Body weight
- Heavier bodies burn more calories doing the same task because they move more mass.
* Example: For general lifting, a 185 lb person often burns more than a 155 lb person in the same 30–60 minute workout.
- Intensity and style
- Long rests, light weights, lots of chatting: lower calorie burn.
* Short rests, compound lifts (squats, deadlifts, rows, presses), circuits or supersets: higher calorie burn, often double or more per hour.
- Duration
- More total minutes = more total calories, though the rate can drop a little if you get tired.
- Muscle mass and training age
- More muscle increases your resting metabolic rate slightly, meaning you burn more calories all day, not just in the workout.
* Over months of lifting, total daily energy burn may rise even if your workouts themselves don’t feel “cardio-like.”
Simple Way to Estimate Your Burn
Many calculators and official tables use a concept called METs (Metabolic Equivalents) to estimate calories.
A common formula is:
Calories burned = MET × weight (kg) × time (hours)
Typical MET values for strength work:
- Light bodyweight / easy resistance: about 3.0 METs.
- General weight training: about 3.5 METs.
- Heavy squats / deadlifts: about 5.0 METs.
- Vigorous powerlifting/bodybuilding style: about 6.0 METs.
Example story :
Imagine Alex weighs 70 kg (about 154 lb) and lifts at a moderate effort for 30
minutes. Using 3.5 METs:
- 3.5 × 70 × 0.5 ≈ 123 calories for that half-hour session.
If Alex instead does a high-density, heavy circuit at 6 METs for 45 minutes:
- 6 × 70 × 0.75 ≈ 315 calories in that workout.
How Weight Lifting Compares to Cardio
Weight lifting usually burns fewer calories per session than hard cardio, but it has different perks.
- Brisk walking: ~150–175 calories per 30 minutes for a 155 lb person.
- Running at 6 mph (10 km/h): ~350+ calories in 30 minutes for that same person.
- General weight lifting: ~100–130 calories per 30 minutes for that person.
Where lifting shines is:
- Building and preserving muscle, which helps keep your metabolism higher over time.
- The afterburn effect (EPOC) after intense strength training, which can add roughly 6–15% more calories on top of what you burned during the session.
So a tough one-hour lifting workout that burns ~400 calories could lead to an extra few dozen calories burned afterward as your body recovers.
Approximate Calorie Burn Table (By Weight & Intensity)
Below is a simplified view based on multiple references and MET-style estimates. Values are approximate and assume 60 minutes of lifting.
| Body weight | Light / casual lifting (1 hour) | Moderate lifting (1 hour) | Vigorous / circuit-style (1 hour) |
|---|---|---|---|
| 125 lb (~57 kg) | ~180–220 calories | [5]~220–300 calories | [1][7]~300–380 calories | [3][5]
| 155 lb (~70 kg) | ~200–260 calories | [7][9]~260–400 calories | [1][3]~350–450+ calories | [3][5]
| 185 lb (~84 kg) | ~230–300 calories | [9][5]~300–430 calories | [1][3]~400–520+ calories | [5][3]
| 215 lb (~98 kg) | ~260–340 calories | [5]~340–470 calories | [1][3]~450–580+ calories | [3][5]
Latest Forum & “What People Are Talking About” Angle
In recent years, especially 2024–2026, weight lifting has shifted from a niche “bodybuilding” thing into a mainstream wellness and longevity habit.
On social and forums, you’ll often see a few recurring viewpoints:
- “Lifting doesn’t burn enough calories to lose weight.”
- Many people compare their smart-watch numbers and see running out-burns lifting per session.
* This is partly true on a per-minute basis, but it misses the long-term benefits of more muscle mass and higher resting burn.
- “Heavy lifting with short rests is my secret fat-loss hack.”
- Some lifters use “metabolic” sessions—circuits, supersets, compound lifts—to get a cardio-like calorie burn plus strength gains.
* Their watches and calculators often show 400–600 calories for a very hard hour, especially if they’re heavier.
- “Calories are cool, but strength is cooler.”
- Another camp focuses less on the exact calories burned and more on performance, bone health, and aging well.
* For them, the calorie burn is a bonus on top of better posture, joint stability, and everyday strength.
A common trend now is mixing lifting with some form of cardio (zone 2, steps, or intervals) so you get both decent weekly calorie burn and steady strength progression.
TL;DR
- Most people burn around 90–250 calories per 30 minutes of weight lifting, depending on weight and intensity.
- Expect roughly 200–500+ calories per hour , with heavier, faster-paced, compound-heavy sessions on the higher end.
- Weight lifting might not beat intense cardio per minute, but it helps build muscle, slightly boosts daily calorie burn, and supports long-term body composition and health.
