Should I use the Cardio Tracker or my machine to figure out how many calories my exercise burned?

SparkPeople’s database estimates the number of calories you burn during exercise, based on generally-accepted rates of calories burned for various activities. Our tracker also bases your individual calorie burn on your weight, because people of different weights burn calories at different rates. (A person who weighs more will burn more calories doing the same activity as a person who weighs less.)

Cardio machines are also estimating your calorie burn. Some can be more accurate than others—for example, if you input variables like your age, height, weight, and gender. However, even the actual machine you use tends to be inaccurate—and some overestimate calories burned by up to 30%.

Both SparkPeople's cardio tracker and cardio machines estimate the number of calories you burn. Estimates are always a problem because you never really know how hard a person is working. For example, two different people could go on a 2-mile walk at a speed of 4 mph, and that could be very easy for a fit person (so they’d burn fewer calories), yet very difficult for a beginner (so they’d burn more calories). Because these exercise trackers don’t really know how hard you are working, the estimates can be a little off.

The best way to monitor calorie burn is to wear a good heart rate monitor. This works better because your heart rate is an accurate measure of how hard you are working, and is directly related to oxygen consumption during exercise (which is the true predictor of calories burned, but you’d have to visit an exercise lab and be hooked up to a machine for that kind of accuracy).

Why does the Fitness Tracker not calculate calories burned through strength training?

Although you will burn calories from strength training, that number is going to vary widely from person to person. It will depend on how much weight you are using, how many sets/reps you are doing, how much rest you take in between sets and how hard you are working. Therefore any estimates would not be reliable. Just consider this to be an extra bonus to your weekly goals!

Circuit training is in the Fitness Tracker, since it is both a cardio and strength training workout. Click here for a description of circuit training.

How do I lose weight from a specific place on my body?

There is no way to target weight loss to a specific area of the body because your body decides where it wants to put on weight and where it wants to take it off. The midsection is a common "problem" area for many people.

    It is hard for me to move and walk allot because I had surgery on my back with hardware,
    that's what the doc. calls it when you have allot of metal.
    I also had surgery on my left foot first, then I had one on me right, then another on my right
    again, and I was getting better and I tripped on my walker wheel and broke my ankle. So
    I really can't run or jump. I'm just thankful that I can sometimes holding on to my walker. - 7/4/2015 5:28:34 PM

    I have had a mild heart attack and have a triple A I am still in the dark as to how much exercise I can do I have just about finished 36 hours of cardio rehab and will be on my own for exercise all I've been told by my Vascular surgeons Nurse is to watch my blood pressure I take medication for high blood pressure and have had no problems. Any advice on how to monitor my blood pressure and what amount of weight I can use for strength training, I am 69 years old and am over weight by 20 lbs.

    Thank you Bill Acebes - 12/25/2014 8:40:58 AM

    Hi There,

    Why is it that when we view the Sparks exercise (s) it never tells you how many
    to do and /or how many sets? e.g. tricep exercise, shows us the exercise but
    that's all...maybe I'm looking in the wrong places. Thanks - 11/12/2014 10:33:37 PM

    Thanks for throwing more light on weight loss.
    When I do cardiovascular exercise I usually have an headache and feel odd. I don't know why. - 9/2/2014 6:48:02 AM
  • Thanks so much for this article. It really helped answer some questions for me. I couldn't believe the fact that some people say they burn over 400 calories on a gym machine whereas I work hard at home with fitness videos and only burn about 150. I was debating this with a co-worker today and said something has got to be wrong. I like your answer that some gym machines over-estimate calories by as much as 30% and also that people who weigh less would burn less calories (I think being a very short person even though I am overweight still I generally do weigh less than many of my colleagues and friends.) At least now I have some answers. - 3/13/2014 11:06:36 AM
  • Unfortunately I have lymph edema and need to keep my legs wrapped most of the day and the only pool I could use has no facilities where I could rewrapp my legs. I am trying to walk but also have breathing problems. I can walk 100 steps at a time and although I'm short of breath afterward a little rest and I'm back up and about in my power chair. I'm up to 7 sessions of walking a day. Three of them are taking my service dog outside. - 2/9/2014 7:28:15 PM

    New to the tracker. Like it very much. One question is do I need to tap it daily to wake it up once the material has been downloaded to the computer. (I don't understand modern technology to well. Old School). Reginetta - 12/17/2013 4:25:12 PM
