Workout Update: 645 Cardio/Lift 4 Day 52

 Day 52 was the rest day in Lift 4, so I did the two recovery workouts in the morning and 645 cardio in the evening. The cardio workout was probably my best one of this round. I was able to jump for the entire 30 seconds of jump knee switches (from P90X) as opposed to just switching my feet, and I could do all 30 seconds of squat jacks (although I did have to slow down a bit on that one) without stopping.
