100 calorie workout?

Maria_Fatima

There's this really popular "100 calorie workout" consisting of 40 jumping jacks, 30 crunches, 20 squats and 10 pushups.
How much does a person have to weigh for these to burn 100 calories?

Edit: I got twice as confused when I saw that this is a pretty easy workout, but when I try to put them separately in MFP, it amounts to like, 50ish calories. That's a whole 100% difference..

I don't think that's even 10 minutes of work, you're not going to get very much of a calorie burn from it. Workouts that assign a burn probably use the upper end of what can be achieved by a pretty heavy male, it's essentially click bait.

I don't know, but I don't know if I could do 40 jumping jacks without dying, LOL.

That's probably a 6 minute net workout (meaning no breaks between exercises). I burn about 150 kcal on about 35 minute on such type of workout, thus it would probably be around 25kcal. Female, 125lbs, 5'65

You would have to do those over and over for quite a while to get close to 100 calories! Like someone else said - that might be 10 minutes worth of exercise. No one is burning 100 calories in 10 minutes.

Do it for 20 minutes straight. That'll get your 100 calories burned.

But it's still not burning 100 calories!

It's 100 total reps but unlikely to be 100 cal burn, as stated above.

Sorry, but energy expenditure has fairly little to do with how difficult it is for you but mostly with the weight (body or weight) you move in a certain direct (horizontally or vertically) and maybe a tiny bit of friction or resistance. Thus 40 jumping jacks would pretty much burn the same amount of calories for you and a twin of you who could do them in 30 seconds.

Yesss, that is extremely exaggerated! Thanks a lot for putting things in better perspective.

I figure about 80-100 calories per mile, or 250-300 calories per hour of moderate paced walking, or low impact aerobics. I agree with everyone else that the "100 calorie workout" is probably more like 25-35 calories.

There's an equation published in various papers that quantifies calories expenditure for running and walking.
Running is around 0.67 x weight in lbs x distance in miles
Walking around 0.3 x weight in lbs x distance in miles
(note: these are net calories. The calories you'd burn anyway just for existing are not included. But those are part of your MFP calorie budget anyway)

It's higher for running because you use more muscles and because running includes a 'jump' where you fight against gravity and have no feet on the ground.

Thank you so much yirara, that's really helpful!
