Week four of the CrossFit open is a chipper, lots of reps for each exercise which tempt you to push hard in the beginning. A good tactic is to break the reps up early so you still have some energy to do the last 15 or so reps well.
The scaled version of this workout has hand release push ups instead of handstand push ups.
