How does Peloton calculate workout output?

Peloton calculates workout output by multiplying the cadence (how fast you pedal) with the resistance level on the bike, and then this figure is translated into a power output number measured in watts. Cadence refers to the revolutions per minute (RPM) of the pedals, whereas resistance reflects how hard those pedals are to turn, simulated by using magnetic resistance or a weighted flywheel. Peloton's proprietary algorithm takes these two input factors along with the time duration to provide an aggregated output, which is often used to quantify the rider's effort during a class. This power output is then displayed as a running total during workouts and is key for assessing performance improvements over time or when participating in competitive leaderboard rankings.
