Corrected read: yesterday was a controlled 45-min workout, 96–128 bpm, with 128 brief/near-isolated rather than sustained over-cap. Today: longer controlled aerobic, not a 6% repeat. Soft cap 120–122 sustained; hard cap 128 with coffee. If HR <112 after min 25 and you feel normal, you may step to 2.9/3%. If HR >122 sustained, drop to 2.5/1%; if near 128, 2.3 flat until settled. STOP if dizzy, chest symptoms, unusual breathlessness, headache, vision changes, or calf pain.
