Scaling:
Today’s workout is a grind. How far into the pain cave do you want to venture? There are two ways to attack this workout: Sprint each effort and bank as much rest as possible before the next interval, or move at a moderate pace and aim to sneak by each minute. If you finish the round of 20, your workout is over. If you didn’t finish the round of 20 in your last attempt, aim to complete one more round than you did last time.
