Next, schedule “oxygen guided sessions.” In these, intensity floats so SmO₂ stays inside a defined window. Cyclists may climb hills but ease off near the top if saturation drops too far. Runners can accelerate only when SmO₂ sits comfortably above 50 %. This method turns every terrain into a smart, self‑adjusting workout. Recovery days become crystal clear: spin or jog until SmO₂ equals resting levels, then call it done.
