It’s a character-building type of day
Today’s workout is the hardest of the 5 Day Challenge. It will be tough, but the workout is short and will leave you with a great sense of accomplishment and well being. This workout can make you faster.
QUICK WORKOUT OVERVIEW:
Warm Up: 15 – 30 minutes
Work: 4 x 1 minute Zone 4 intervals, with 2 minutes active rest in between.
Cool Down: 10 minutes, more or less as you wish.
About Zone 4
Zone 4 is HARD INTENSITY. You will push above and beyond “race pace” (you should only be able to hold this effort for 5 minutes maximum if you had to).
You’re in Zone 4 when:
- Your breathing is heavy and rapid, and you are becoming short of breath.
- Speaking even single words is difficult.

Why Zone 4? Zone 4 training increases VO2 max via heart adaptations by challenging the heart to pump more blood at a higher rate.
Workout Instructions
