The truth about all of these calorie counting devices is that there is absolutely no way for them to give you an accurate number. Caloric expenditure shows the energy used for work and the definition of work is the product of force and distance. Is it possible for those trackers to measure these two components while you squat or do your jumping jacks? I don't think so! Although we can't deny the motivational effect of these gadgets for many individuals, fitness professionals shouldn't rely on the numbers out of their client's trackers to set up the exercise plans.
