The Outsiders Adds Four Advanced Metrics for Power-Based Training

Apple’s fitness app The Outsiders has released version 1.6, adding four new power‑based metrics—Relative Intensity, Variability Index, Efficiency Factor, and Aerobic Decoupling—to its session summary for cyclists and runners. The metrics aim to quantify session demand, pacing consistency, power‑heart‑rate efficiency, and sustained aerobic performance. They are accessible through the Outsiders Absolute subscription, which also offers personalized training goals introduced earlier this year. The update rolls out now on the App Store.
