Yesterday was controlled: HR 90–124 from 2:34–3:12 with good 3-min recovery (-24 bpm). Sleep 7h supports a normal controlled day. Assuming AC keeps garage near 75–77°F. If actual garage is ≥80°F/stuffy, run Steady at 2.6 mph / 1% and skip Finish; if ≥84°F, convert to easy Z2 only. Soft cap: 120–122 sustained. If HR >122 for 2+ min, drop 1% incline or 0.2 mph; if near 128, go 1.5 mph flat and end if not settling. If HR is <112 at min 20 and garage is cool, add only +0.1 mph OR +1% incline, not both. No 5% challenge today. STOP if dizzy, chest symptoms, unusual shortness of breath, headache, vision changes, or calf pain.
