Calories Burned Weight lifting at a light effort at 75 kg — 225 kcal per Hour
Weight lifting at a light effort at 75 kg (154–176 lb) burns about 225 kcal per hour. That figure comes from the activity's MET value of 3.0 in the 2011 Compendium of Physical Activities, multiplied by body weight: 3.0 × 75 kg × 1 hour = 225 kcal. This page works the numbers out in full — for 15, 30, 45, 60 and 90 minutes, across all four weight bands, and against four comparable activities at the same weight — so you can plan sessions with real figures instead of guessing.
Weight lifting at a light effort — easy sets with light weights, long rests, a pace that never leaves you breathless — burns about 225 kcal per hour at 75 kg. The Compendium rates it at 3.0 METs, which is a light intensity: roughly the same as walking the dog or doing Pilates. That low figure surprises people who expect lifting to burn like running, but the maths is honest — light lifting is mostly resting between short sets, and resting burns little. The value of light lifting is not in the calories it burns during the session, but in what it builds over months: strength, balance, bone density and the muscle that raises your daily energy use.
It suits beginners learning the lifts, older adults building strength safely, people returning to exercise after illness or injury, and anyone on a recovery day who wants to move without taxing their system. It is also the right intensity for a first month of lifting, when the goal is to learn the movements rather than to chase numbers. If you are already strong, light lifting is a warm-up or a deload week, not a training stimulus — and that is fine, because deload weeks are part of a good programme, not a sign of laziness.
If you sit in this weight band, your figures will be higher than those on the lighter pages — that is expected, because a heavier body costs more energy to move. Do not read a bigger number as a better workout: the effort is the same, and the calorie total is physics, not a score. What matters is the effort and the consistency, not the raw number.
Calculate your own numbers
Use the Calorie calculator to work out your own burn for weight lifting at a light effort at your exact weight and session length. Enter your weight, pick the activity and set the duration, and the tool applies the same MET formula shown below. Use the one rep max calculator as well if you want to plan your working weights from a tested lift.

The formula, shown and cited
The standard way to estimate the energy cost of an activity is the MET formula from the Compendium of Physical Activities (Ainsworth et al., Medicine & Science in Sports & Exercise, 2011; 43(8): 1575–1581):
Calories (kcal) = MET × body weight (kg) × duration (hours)
One MET is the energy you use sitting quietly at rest — about 1 kcal per kilogram of body weight per hour. An activity rated at 3.0 METs therefore uses 3.0 times as much energy as resting. The Compendium's MET values come from published studies that measured oxygen use during each activity, so they are measured averages, not guesses. The value used here, 3.0, is the one recorded for weight lifting at a light effort in the FitCalc activity data.
Worked through for this page:
- MET for weight lifting at a light effort: 3.0
- Body weight: 75 kg (the midpoint of the 70-80 kg band, 154–176 lb)
- Duration: 1 hour
- Calculation: 3.0 × 75 × 1 = 225 kcal
For a 30-minute session the same calculation is 3.0 × 75 × 0.5 = 112 kcal. Nothing else is hidden in the maths — if your weight or duration changes, only those two numbers change.
Your numbers at 75 kg
| Duration | Calculation | Calories burned |
|---|---|---|
| 15 minutes | 3.0 × 75 × 0.25 | 56 kcal |
| 30 minutes | 3.0 × 75 × 0.5 | 112 kcal |
| 45 minutes | 3.0 × 75 × 0.75 | 169 kcal |
| 60 minutes | 3.0 × 75 × 1 | 225 kcal |
| 90 minutes | 3.0 × 75 × 1.5 | 338 kcal |
That is about 3.8 kcal per minute of weight lifting at a light effort at this weight. A short session still counts: even 15 minutes burns 56 kcal, and three 15-minute sessions across a day add up to the same 169 kcal as one 45-minute session.
How the burn changes with body weight
The MET value stays the same — it describes the activity, not the person — but the calorie total scales with weight, because a heavier body costs more energy to move:
| Body weight | Calories per hour | Calories per 30 minutes |
|---|---|---|
| 55 kg | 165 kcal | 82 kcal |
| 65 kg | 195 kcal | 98 kcal |
| 75 kg | 225 kcal | 112 kcal |
| 85 kg | 255 kcal | 128 kcal |
Two people doing the same activity for the same time can therefore burn quite different amounts, and that is expected — it is physics, not a mistake in the formula. If your weight sits between two rows, your figure sits between the two values.
How weight lifting at a light effort compares
Here is weight lifting at a light effort against four other activities at the same 75 kg, all using the same MET formula:
| Activity | MET | Calories per hour at 75 kg |
|---|---|---|
| weight lifting at a light effort | 3.0 | 225 kcal |
| walking the dog | 3.0 | 225 kcal |
| Pilates | 3.0 | 225 kcal |
| tai chi | 3.0 | 225 kcal |
| calisthenics at a moderate effort | 3.8 | 285 kcal |
Use this table to choose, not to judge. A higher number means a harder session, not a better one: the activity you enjoy and repeat three times a week beats the activity that burns more per hour but that you quit after a fortnight. Mixing intensities across the week — one harder session, two easier ones — is usually more sustainable than doing the hardest activity every time.
Fitting weight lifting at a light effort into your week
| Sessions per week | 30 minutes each | 60 minutes each |
|---|---|---|
| 2 sessions | 225 kcal | 450 kcal |
| 3 sessions | 338 kcal | 675 kcal |
| 5 sessions | 562 kcal | 1125 kcal |
A good light session is 30–45 minutes covering five or six exercises, two or three sets of 12–15 repetitions each, with rests between sets. At this weight, 30 minutes burns about 112 kcal and 45 minutes about 169 kcal — modest figures, and that is expected. Two or three sessions a week is enough to build a foundation; after four to six weeks, most people are ready to add weight and move towards a moderate effort. Keep a simple log of the weight and repetitions for each exercise, because progress in lifting is measured in the log, not in the calorie count.
How to use the result
Use the figure on this page to set honest expectations, not to count a light session as a big calorie burn. Add the session's calories to your total daily energy expenditure for that day, and remember the estimate carries roughly 10–20% uncertainty. The real return on light lifting is the muscle you build, which raises the calories you burn all day, every day — a return the session figure does not show. If you are aiming to lose weight, keep the deficit modest — 300–500 kcal a day is a common, sustainable range — and keep your total intake above the safety floors of 1,200 kcal a day for women and 1,500 kcal a day for men unless a healthcare professional advises otherwise. Eat enough protein to support the muscle you are building: 1.6–2.2 g per kg of body weight a day is the published range for lifters and dieters, and kidney disease changes the answer, so check with a healthcare professional if that applies to you.
Light lifting means weights you could lift for 15–20 repetitions with good form, resting 60–90 seconds between sets. The form matters more than the weight: for a squat, keep your chest up and your knees tracking over your toes; for a press, keep your wrists straight and your core braced; for a deadlift, keep the bar close and your back flat. Move the weight under control, taking about two seconds to lift and two to lower, rather than dropping it or bouncing it. If a set leaves you gasping, the weight is not light — turn it down.
What the number does NOT tell you
The MET formula measures only the energy used during the session, and for light lifting that is a small part of the story. It does not measure the muscle built, the bone density gained, the balance improved, or the calories your new muscle burns at rest afterwards. It also does not know how much of the hour you spent resting between sets, how heavy the weights actually were, or how fit you are. And it cannot tell you whether lifting is safe for you: if you have a heart condition, high blood pressure, a joint problem or any other health concern, check with a healthcare professional, and learn the lifts from a qualified coach before adding weight.
Frequently asked questions
How many calories do I burn weight lifting at a light effort for 30 minutes at 75 kg?
About 112 kcal. The maths is 3.0 METs × 75 kg × 0.5 hours = 112 kcal. That is an estimate from the Compendium average — your real burn depends on the weights you use, how long you rest between sets and your fitness. If you weigh more or less than 75 kg, use the weight table above to read your own figure.
Why does light weight lifting burn so few calories?
Because most of a light session is resting between short sets. The Compendium rates light lifting at 3.0 METs — about the same as walking the dog — and the hourly figure at 75 kg is only about 225 kcal. The value of lifting is not the session burn but the muscle it builds, which raises the calories you burn all day, every day, and the strength, balance and bone density that come with it.
Is light weight lifting enough to build strength?
For a beginner, yes — for the first four to six weeks, light weights with good form build strength, coordination and confidence. After that, most people need to add weight to keep progressing, because muscles adapt to the load they are given. Two or three sessions a week, adding a little weight when 15 repetitions feel easy, is a sound pattern.
Does the calorie burn change if I weigh more or less than 75 kg?
Yes, directly. Calories = MET × weight in kg × hours, so the burn scales with body weight. At 55 kg the same hour of light weight lifting burns about 165 kcal; at 85 kg it burns about 255 kcal. The MET value itself does not change with weight — it describes the intensity of the activity.
How accurate is the 3.0 MET value for light weight lifting?
It is a population average from the 2011 Compendium of Physical Activities (Ainsworth et al.), which compiled measured energy costs across published studies. Individuals vary by roughly 10–20% around the average, and lifting varies more than most activities because the rest periods and the weights used differ so much between people. Treat 225 kcal per hour as a planning estimate, not a precise measurement of your own session.
Estimates only, not medical advice. Minimum safe intakes: 1,200 kcal/day women, 1,500 kcal/day men — consult a healthcare professional before a very-low-calorie diet.
