Peloton bikes and treadmills estimate energy expenditure using a proprietary algorithm that considers several factors, primarily the user’s weight, the resistance level or incline, and the cadence or speed. Power output, derived from these metrics, is a key element in these calculations. Output is displayed in a personalized metric called “KJ,” reflecting kilojoules of work performed, which is then converted to calorie estimates.
Accurate estimations of energy expenditure are crucial for individuals tracking fitness progress and managing weight. Understanding this information allows users to balance calorie intake with output, a cornerstone of achieving health and fitness goals. Historically, exercise equipment relied on simpler calculations, often overlooking individual factors like weight, leading to potentially inaccurate readings. Modern approaches, like Peloton’s, aim to provide more personalized and precise estimations.
