Last week we looked at high/low output cycling in the weekly workouts. Now, we're going to explore workload extension. In two workouts (any of your choosing) this week, get to the end of the Primary section, and then add 10-20% more volume (at same but not higher intensity). This is as much mental as it is physical and it's one way we build not just endurance but all-day durability in the BEAST.
The cover photo for this challenge says it all. Can you do everything you want (in work, sport, and life) using 1/2 of what you've got (your total capacity)? This is the type of engineering that makes machines last a long time. The same is true for our bodies. Build them up so that most of what we do feels relatively easy.
