It's Niner Niner! Our Weekly Challenge is SHOWING UP WITH YOUR "A" GAME. You are tasked to be ready, focused, an maximally invested in 1 each of Workouts A, B, and C this week. In the other (secondary) version of each workout, bring the B game, as in just cruise through it with a little less purpose and effort. This undulating output is nonlinear. Instead of thinking you either have to totally smash everything, or do every workout at a B+ level, go high/low in your sessions of the same letter. This is a peak performance secret and it will enable you to bump up fitness and recover better as well.
