No, it's not a mid-life crisis term, it's the Workout of the Day from Calgary Crossfit. See it here.
My time was 24:43. After which I followed up with 30 min treadmill incline walking 7.0 incline, 4.0 speed.
Going to see my nutritionist, Jason at Balanced Energy Systems this evening for a consult. Looking forward to seeing someone so positive and motivational!
