Workout Update: 645 Cardio/Lift 4 Day 20

For day 20, I just did the 645 cardio workout in the evening. I did not do the recovery workouts from 645 since I started incorporating them after the 645 workouts during the week. Since it is an off day from Lift 4 I mixed in higher intensity, higher-impact exercises, including one from P90x's plyometrics workout.
