It's incredibly convenient—after 30 minutes on the treadmill, the display shows exactly how many calories you've burned. Yet most cardio machines rely on incomplete data for these estimates.
They primarily factor in your activity level, overlooking crucial variables like gender, age, height, and body fat percentage that truly determine calorie expenditure.
Researchers at the University of California tested the accuracy of popular fitness machines. Treadmills overstated calorie burn by an average of 13%, stationary bikes by 7%, and cross-trainers by a staggering 42%.
Indulging in a post-workout slice of pie? You might consume more calories than you actually burned.
