Workout Update: 645 Cardio/Chalean Extreme Day 4

On day 4, I did 645 cardio in the morning and Burn Intervals in the evening. Since the interval workout contains many HIIT exercises, I did a lower-impact version of the 645 cardio workout. It has been a long time since I did that workout, and it was tough. I used light weight (5 lbs for the bicpes curls, rows, and squats and 3 lbs for the shoulders and triceps exercies). I still find Skip irritating as all hell (especially given that he lies about how much weight he is using) and try to tune him out, but I loved seeing my workout crush, Toni, again.
