Correction applied: yesterday's high HR was from drinking water/Apple Watch artifact, not sustained load. Since you also had to dial up settings to reach the target, today is controlled moderate, not recovery Z2 Forecast-derived Fremont garage ~78–84°F because it is sunny (outside ~75°F noon, ~81°F afternoon). Actual thermometer overrides. If garage ≥82°F or stuffy, reduce Push to 2.7/2% and keep it Z2/moderate-light Target Push HR 115–124. If HR is <115 after minute 20 and garage is <80°F, add one small notch only: 3.0/3% or 2.9/4%, not both. If still low after 3 minutes, add the other notch If HR >124 for more than 2 minutes, drop to 2.6/1%; sustained >125 walk flat/easy. Hard stop 128 with AM coffee Small single-point spikes while drinking water do not count; judge sustained HR for 60–120 seconds. STOP if headache, dizzy, vision changes, chest symptoms, unusual shortness of breath, or calf pain.
