Monday was clean: HR 94–123 from 12:09–12:51, with a controlled rise/peak and cooldown. Tue/Wed were rest/missed days, and 8h sleep is good readiness. Garage is already 81.6°F, so today is longer-not-harder controlled aerobic, not make-up intensity. If garage reaches ≥84°F/stuffy, skip Finish and start Cool at min 35; if ≥86°F or uncomfortable, stop at 20–25 min easy. Soft cap: 120–122 sustained. If HR >122 for 2+ min, drop to 2.3 mph flat; if near 128, go 1.5 mph flat and end if not settling. If HR is <108 at min 20 and garage feels OK, add only +0.1 mph OR +1% incline, not both. No 3.0 mph / 5% push in this heat. STOP if dizzy, chest symptoms, unusual shortness of breath, headache, vision changes, or calf pain.
