Workout Update: 645 Cardio/Lift 4 Day 46

 Day 46 was shoulders and arms in Lift 4 and the 645 cardio in the evening. The Lift 4 workout was a circuit-style workout, and it was tough. I found myself having to lower the amount of weight I used for multiple exercises in both blocks of the circuit, and in the burnout block. I was able to get at least one set in with the higher amount of weight for every exercise in each block. However, by the second and third sets I was having to reduce the amount of weight, sometimes for each exercise. For the 645 cardio workout I did a harder version by swapping out exercises from Insanity and P90x plyometrics.
