So you want to know how many jumping jacks to burn 100 calories. Fair question. Jumping jacks (or star jumps, as we call them in Australia and the UK) need no gear and no gym, so they are an easy way to squeeze in some cardio.
The honest answer depends mostly on your body weight and how hard you jump. Below you’ll find a chart by weight, a calculator, the maths behind it and a simple workout. Every number is an estimate, and we show you exactly where it comes from.
Key takeaways
- How many jumping jacks to burn 100 calories? Most adults need roughly 450 to 900 fast ones, or about 8 to 15 minutes.
- 100 jumping jacks burn only about 11 to 22 calories, depending on your weight.
- For weight loss, jumping jacks work best as part of regular activity plus sensible eating, not on their own.

How Many Jumping Jacks to Burn 100 Calories?
Most adults burn 100 calories with roughly 450 to 900 jumping jacks, or about 8 to 15 minutes of brisk, non-stop jumping. A 70 kg (154 lb) person needs about 11 minutes, or roughly 650 jacks at one per second. Heavier people need fewer jacks; lighter people need more.
That’s 100 kilocalories, the “calories” on food labels. In kilojoules it’s about 420 kJ.

Jumping Jacks by Body Weight
Find the row closest to your weight. The jack counts assume a brisk pace of about one per second (60 a minute).
| Body weight | Calories per minute | Minutes to burn 100 kcal | Jacks for 100 kcal (at 60/min) | Calories from 100 jacks |
|---|---|---|---|---|
| 50 kg (110 lb) | 6.6 | 15 | about 910 | 11 |
| 60 kg (132 lb) | 7.9 | 13 | about 760 | 13 |
| 70 kg (154 lb) | 9.2 | 11 | about 650 | 15 |
| 80 kg (176 lb) | 10.5 | 9.5 | about 570 | 18 |
| 90 kg (198 lb) | 11.8 | 8.5 | about 510 | 20 |
| 100 kg (220 lb) | 13.1 | 7.6 | about 460 | 22 |
If you jump faster than one per second, you’ll do more jacks in the same time. The minutes column is the steadier guide.
Calories Burned Per Minute of Jumping Jacks
Brisk jumping jacks burn about 7 to 13 calories per minute for most adults: roughly 8 at 60 kg, 9 at 70 kg, 10.5 at 80 kg and 13 at 100 kg. Ten minutes burns about 80 to 130 calories. Lighter, slower jacks burn about half that.
| Body weight | 10 minutes | 20 minutes | 30 minutes |
|---|---|---|---|
| 60 kg (132 lb) | 79 kcal | 158 kcal | 236 kcal |
| 70 kg (154 lb) | 92 kcal | 184 kcal | 276 kcal |
| 80 kg (176 lb) | 105 kcal | 210 kcal | 315 kcal |
| 100 kg (220 lb) | 131 kcal | 263 kcal | 394 kcal |
How the Jumping Jacks Calorie Maths Works
Exercise scientists rate activities in METs. One MET is roughly the energy you use sitting quietly, defined as 3.5 ml of oxygen per kilogram per minute.
The 2024 Adult Compendium of Physical Activities lists vigorous calisthenics, including jumping jacks and burpees, at 7.5 METs. There’s no separate entry for jumping jacks alone, so this is the closest official value.
The Compendium gives this conversion:
Calories per minute = MET × 3.5 × body weight in kg ÷ 200
Here’s a worked example for a 70 kg person:
- 7.5 × 3.5 × 70 ÷ 200 = 9.2 calories per minute
- 100 ÷ 9.2 = about 11 minutes
- 11 minutes × 60 jacks = about 650 jumping jacks
As a sanity check, Harvard Health lists about 306 calories for 30 minutes of vigorous calisthenics at 155 lb. That’s around 10 a minute, close to our 9.2.
Why your number will be different
The Compendium’s own authors say it wasn’t built to give the precise energy cost for an individual. It doesn’t adjust for age, sex or body composition. So treat any answer to how many jumping jacks to burn 100 calories as a ballpark, ours included.
Effort matters too. Lazy, half-height jacks are closer to moderate effort. The Compendium rates moderate calisthenics at 3.8 METs, which roughly halves the burn.
One more honest detail: the formula counts total calories, including about 1 MET you’d burn anyway sitting on the couch. The extra burn is roughly 13% lower.
And sweat isn’t a reliable sign of calories burned. We explain why in does sweating burn calories?
Calories in 100 Jumping Jacks
At one jack per second, 100 jumping jacks take under two minutes. That burns roughly 11 calories at 50 kg, 15 at 70 kg and 22 at 100 kg.
So no, 100 jumping jacks won’t burn 100 calories. You’d need several sets of them.
How many calories do 50 or 200 jumping jacks burn?
At one jack per second, 50 jumping jacks take under a minute and 200 take just over three minutes.
| Body weight | 50 jumping jacks | 100 jumping jacks | 200 jumping jacks |
|---|---|---|---|
| 50 kg (110 lb) | about 5 kcal | about 11 kcal | about 22 kcal |
| 70 kg (154 lb) | about 8 kcal | about 15 kcal | about 31 kcal |
| 100 kg (220 lb) | about 11 kcal | about 22 kcal | about 44 kcal |
Burning 500 or 1,000 Calories With Jumping Jacks
Using the same formula, here’s the time and rough jack count for bigger targets:
| Body weight | 500 kcal | 1,000 kcal |
|---|---|---|
| 60 kg (132 lb) | 64 min, about 3,800 jacks | 127 min, about 7,600 jacks |
| 80 kg (176 lb) | 48 min, about 2,900 jacks | 95 min, about 5,700 jacks |
| 100 kg (220 lb) | 38 min, about 2,300 jacks | 76 min, about 4,600 jacks |
Very few people can keep vigorous jumping going for an hour or more. It’s also a lot of impact on your ankles, knees and calves.
For big calorie goals, mixing activities works better. Our guide to burning 1,000 calories a day shows how to spread it out.
A 15-Minute Jumping Jacks Workout for 100 Calories
Non-stop jacks get dull fast. This interval plan gives you about 10 minutes of actual jumping, which covers 100 calories for most people around 80 kg.
- Warm up (2 minutes): march on the spot, then add arm circles.
- Main set (about 13 minutes): 10 rounds of 60 seconds of brisk jumping jacks, then 20 seconds of marching on the spot.
- Cool down (1-2 minutes): walk around, then stretch your calves and shoulders.
Lighter than 80 kg? Add a few rounds; check the chart above for your minutes. New to exercise? Start with three or four rounds and build up week by week.

Form tips for better jumping jacks
- Land softly on the balls of your feet, heels kissing the floor.
- Keep your knees soft, never locked, and let them track over your toes.
- Brace your core lightly so your back doesn’t arch.
- Go full range: hands meet overhead, feet go wider than your shoulders.
- Pick your surface: a mat or wooden floor is kinder than concrete. Wear supportive shoes.
Low-Impact Alternatives (and How They Compare)
If jumping bothers your knees, ankles or pelvic floor, you don’t have to jump. Step-out jacks are a good start: tap one foot to the side at a time while your arms go up.
The Compendium has no value for step-out jacks. The closest entries are below, with minutes to burn 100 calories for a 70 kg person.
| Activity (Compendium entry) | METs | Minutes for 100 kcal at 70 kg |
|---|---|---|
| Rope skipping, general | 11.0 | 7.5 |
| Vigorous calisthenics, incl. jumping jacks | 7.5 | 11 |
| Step aerobics, 4-inch step | 5.5 | 15 |
| Elliptical trainer, moderate effort | 5.0 | 16 |
| Aerobic dance, low impact, moderate effort | 4.8 | 17 |
Low-impact options take a few minutes longer to reach 100 calories. Many people can keep them going for longer, though, which often evens things out.
Are Jumping Jacks Good Cardio?
Yes. Brisk jumping jacks are vigorous cardio: the Compendium rates them at 7.5 METs, and the US guidelines treat anything at 6 METs or more as vigorous. They raise your heart rate within a minute, need no gear and fit into any spare five minutes.
The CDC says adults need 150 minutes of moderate activity a week, or 75 minutes of vigorous activity such as jogging or running. Because jumping jacks are vigorous, every minute of them counts toward that 75-minute target.
They also count as bone-strengthening activity in the US guidelines. The trade-off is impact. If your joints complain, swap in the low-impact options above for some of your sessions.
Is 100 Jumping Jacks a Day Enough?
One hundred jumping jacks a day is a great habit starter. On its own, though, it’s only around 11 to 22 calories, so don’t expect it to shift your weight.
The US Physical Activity Guidelines recommend adults get 150 to 300 minutes of moderate activity a week, or 75 to 150 minutes of vigorous activity. Brisk jumping jacks count as vigorous, because they’re above 6 METs.
The guidelines also list jumping jacks as a bone-strengthening activity. And they note that combining physical activity with eating fewer calories tends to work best for weight loss.
A quick way to check your effort is the talk test. If you can’t say more than a few words without pausing for breath, you’re working vigorously.
The guidelines put it simply: some physical activity is better than none. If 100 jacks a day gets you moving, that’s a win. Then build from there.
