Exercise Caloric Claims: Don’t Believe Them

century ride

It seems that every exercise video or fitness program claims that if you buy their system, you can burn up to 1000 calories in an hour. If that were the case I would be able to eat brownies every day and still lose weight (I wish!). Note the key words they use in their sales pitches:  up to, may, can, possible…etc. Unless you weigh a lot and have large muscles, it’s incredibly unlikely that you will burn 1000 calories in a mere hour of any type of exercise.

Here’s some data that I thought was interesting and quite eye-opening from WebMD’s calorie counter:

If you weigh 115 pounds & do high-impact aerobics for 1 hour you will burn 420 calories
If you weigh 185 pounds and do high-impact aerobics for 1 hour you will burn 676 calories (even at the higher weight, this person doesn’t burn 1000 cal/hr)

 

If you weigh 115 pounds and Rollerblade 8 miles in 1 hour you will burn 241 calories (That’s it? Yikes!)
If you weigh 185 pounds and Rollerblade 8 miles in 1 hour you will burn 388 calories

 

If you weigh 115 pounds and walk 3 miles in 1 hour you will burn 238 calories
If you weigh 185 pounds and walk 3 miles in 1 hour you will burn 383 calories

 

If you weigh 115 pounds and weight-train for 1 hour you will burn 289 calories (OMG! That’s all?)
If you weigh 185 pounds and weight-train for 1 hour you will burn 464 calories

 

If you weigh 115 pounds and do yoga for 1 hour you will burn 191 calories
(They’re probably referring to easy yoga!)
If you weigh 185 pounds and do yoga for 1 hour you will burn 308 calories

 

If you weigh 115 pounds and clean for 1 hour you will burn 194 calories
If you weigh 185 pounds and clean for 1 hour you will burn 313 calories

 

From this data you can see that the less you weigh, the fewer calories you burn. This is why it’s really hard for tiny folks to lose any weight at all, and why it’s easier for heavy folks to lose weight quickly. Even though this information is from WebMD, a reliable site, they’re approximations. A younger person with denser muscles will burn more calories than a senior citizen even if they are the same weight. Age, muscle mass, metabolism, and how often you move when you’re not exercising has an effect on calories burned. My husband kidded me that he burns more calories lying on the couch reading the paper than I do in a one hour high-intensity plyometric workout.

  1. These look effective, hovewer, wish I could see what the band is attached to in first exercise. What if you don’t have someone to hold it for you in next exercise? Is there a work around?

    • What blog are you referring to? So far, I haven’t posted any exercises with bands. On the blog titled, Exercise Caloric Claims, the cyclist is wearing a heart rate monitor on her wrist.

  2. I’m impressed, I have to admit. Rarely do I come across a blog that’s equally
    educative and engaging, and let me tell you, you have hit
    the nail on the head. The problem is an issue that not enough people are speaking intelligently about.
    I’m very happy I found this during my search for something
    concerning this.
