How Many Calories 120 Push-Ups Burn — Realistic Ranges

Calorie burn from 120 push-ups swings with body weight, intensity, and how long those reps take. A 70 kg person finishing 120 reps in about five minutes at a strong, steady pace lands near 49 kcal based on the standard MET equation. Take longer at a gentler tempo and the number sits closer to the mid-30s. Heavier bodies spend more energy; lighter bodies spend less.

To keep things practical, the ranges below assume two common scenarios for finishing 120 reps:

• Moderate feel: controlled tempo, small pauses; treat as 3.8 MET calisthenics for about 8 minutes.
• Vigorous feel: steady, minimal pauses; treat as 8.0 MET calisthenics for about 5 minutes.

Estimated Calories For 120 Push-Ups By Body Weight

Body Weight	Moderate 3.8 MET (~8 min)	Vigorous 8.0 MET (~5 min)
50 kg	≈27 kcal	≈35 kcal
55 kg	≈29 kcal	≈38 kcal
60 kg	≈32 kcal	≈42 kcal
65 kg	≈35 kcal	≈46 kcal
70 kg	≈37 kcal	≈49 kcal
75 kg	≈40 kcal	≈52 kcal
80 kg	≈43 kcal	≈56 kcal
85 kg	≈45 kcal	≈60 kcal
90 kg	≈48 kcal	≈63 kcal
95 kg	≈51 kcal	≈66 kcal
100 kg	≈53 kcal	≈70 kcal

These figures come from two pieces of widely used guidance: the Compendium of Physical Activities lists calisthenics at 3.8 MET (moderate) and 8.0 MET (vigorous), and the standard energy equation used by coaches and trainers: MET × 3.5 × kg ÷ 200 × minutes.

What Changes The Number

Body Weight And Intensity

Energy scales with mass. Two people matching pace and form won’t spend the same calories if one weighs 60 kg and the other 90 kg. Intensity matters the same way. Fast, snappy reps feel like 8 MET work. Controlled sets with longer lowers feel like 3.8 MET work.

Tempo, Rest, And Set Design

Pace alters both minutes spent and how “hard” the work is. A brisk cadence trims minutes while keeping the intensity high. Slower reps stretch minutes but usually feel less explosive. Breaks cut the active time; brief pauses don’t add much energy on their own.

Technique That Keeps Things Honest

Chest meets depth, elbows track well, core stays tight, and full lockout. Half reps shave time without the same training value. Strict range of motion tends to raise effort per rep, even if you move a touch slower.

How We Estimated It (The MET Method)

MET stands for metabolic equivalent. One MET equals resting energy use, and for calculations it’s set to 1 kcal per kilogram per hour, or an oxygen uptake of 3.5 ml/kg/min. That standard definition comes from the Compendium and exercise science texts. Calorie math for activities then uses this simple line:

Calories per minute ≈ MET × 3.5 × body-weight(kg) ÷ 200

The Formula In Plain Words

Pick a MET value that reflects the work (calisthenics moderate vs vigorous), multiply by 3.5, multiply by your weight in kilograms, divide by 200, and then multiply by minutes spent actually moving. That’s it. The same approach underpins many trusted charts, including Harvard’s long-running “calories burned in 30 minutes” tables for calisthenics in different weight brackets.

Example For 70 Kg — Vigorous Pace

Vigorous calisthenics is 8.0 MET in the Compendium. Using five minutes of work to finish 120 reps:

• Kcal/min ≈ 8.0 × 3.5 × 70 ÷ 200 = 9.8
• Total ≈ 9.8 × 5 ≈ 49 kcal

Example For 70 Kg — Moderate Pace

Moderate calisthenics is 3.8 MET. If those 120 reps take around eight minutes with a steady cadence and mini pauses:

• Kcal/min ≈ 3.8 × 3.5 × 70 ÷ 200 = 4.655
• Total ≈ 4.655 × 8 ≈ 37 kcal

Both paths make sense: you either spend less time at a higher intensity or more time at a lower intensity. The totals end up in the same ballpark, which is why most lifters see 120 good reps fall in a ~35–65 kcal window.

Set Strategies For 120 Reps

Pick a plan that fits your current strength and keeps form sharp. Here are four common ways to get the job done and what that means for time and energy for a 70 kg body.

120 Push-Ups: Time And Estimated Calories (70 kg)

Cadence & Sets	Active Time	Est. Kcal
Fast set (≈40/min, near-max)	~3 min	≈29 kcal
Steady set (≈30/min, smooth)	~4 min	≈39 kcal
4×30 with brief rests	~4 min active	≈39 kcal
Tempo holds (≈8 min total, moderate)	~8 min	≈37 kcal

These rows treat the quicker plans as vigorous (8 MET) and the tempo plan as moderate (3.8 MET). If you add longer rests, total session time rises, but only the minutes you’re actually moving count toward the MET math.

Ways To Nudge Burn Up Or Down

• Make reps stricter: full chest-to-floor depth, one-second pause at the bottom, full lockout. Same 120 reps, a bit more effort per rep.
• Try incline, standard, then decline: three equal chunks of 40 reps change the leverage and recruit fresh fibers without wrecking form.
• Add a finisher: 2×10 burpees or push-up to pike hops will bump the session by roughly 15–25 kcal for most people.
• Walk after: a brisk five-minute lap tacks on another ~25–30 kcal for a 70 kg body, based on typical walking MET values.

Common Pitfalls That Skew Estimates

Counting Only The Clock

Long sessions stuffed with resting don’t mean you burned more from push-ups. The equation cares about the minutes you’re moving at that MET level. A tidy, focused block of work beats a drawn-out grind with sloppy reps.

Ignoring Range And Body Angle

A shallow angle or half depth turns 120 into a different exercise. Keep a straight line from head to heels, touch a target near chest level, and lockout. Adjust the angle (incline or knees) if strict reps fall apart.

Using One Number For Everyone

Energy scales with weight and tempo. Borrow the chart that matches your body and pace, then track your own cadence the next time you run 120 reps.

Where The Numbers Come From

The Compendium of Physical Activities lists calisthenics like push-ups at 3.8 MET (moderate effort) and 8.0 MET (vigorous effort). The energy equation widely taught to trainers and coaches can be found in ACE’s MET guidance. Together, they give you a consistent way to estimate calories for a fixed rep target like 120.

Build A Smarter 120-Rep Session

Warm Up And Groove The Pattern

Two rounds of 10 scapular push-ups, 10 knee push-ups, and 20-second high-plank holds gets joints ready and sets clean positions.

Pick A Rep Map You Can Own

Start with 6×20 or 8×15 and short rests. Move to 4×30 as strength and endurance rise. When 120 unbroken with strict reps is there, chase it once a week, not every day.

Mix Variations Without Guesswork

Close-grip, pause reps, and deficit variations raise effort without guessing. Keep total reps at 120 and swap one block each week.

Bottom Line For Tracking

If you weigh around 60–80 kg, 120 well-performed push-ups will usually cost 35–60 calories. Lighter or heavier bodies and faster or slower tempos slide that band a little. Use the MET formula and the tables here to set expectations, then log your own cadence and rest times so the estimate gets tighter over time.
