Workout Update: Lift 4/Shaun 20/645 Cardio hybrid: Day 39

Day 39 was the Pure Cardio workout from Shaun 20 in the morning and Shoulders (Intervals) from Lift 4 in the evening. I found the shoulder workout was a lot more challenging than last week. So, although I started with the same amount of weight for each exercises as I used last week, I had to reduce the amount of weight I used for most of the exercises by the third set in each block (aside from shoulder presses and upright rows).
