Expect most of us distance fans will get geeked up over her workouts:
"Muhammad spent the fall of 2018 focusing on strength and foundational work during long and arduous training days. Among the early workouts that stuck out were multiple 12 x 400-meter sessions with 60 seconds rest. Each lap had to be run between 70 and 72 seconds. She would nail the times and come back the next day to run a mile time trial anywhere from 5:07 to 5:17. For 800-meter work, she could comfortably run 2:06 and she believed in a race, she’d dip under two minutes."
