Workout Update: 654 Cardio/Lift 4 Hybrid: Day 18

Day 18 was the 645 cardio routine in the morning and the shoulders workout in Lift 4. This week's shoulder workout was an interval workout, so it was one of the quicker workouts, which was nice.  I was able to increase the amount of weight on the various exercises, which kind of surprised me, given that shoulders have been my weak point for the past few rounds of workouts.
