Workout Update: 645 Cardio/Chalean Extreme Day 1

I decided to go back to one of my older workouts as my "main" workout for the next few months: Chalean Extreme. Today was day 1, so I did 645 cardio in the morning and Burn Circuit 1 from CE in the evening. The cardio workout was fine. I selected more intense/higher-impact exercises since CE does not have a HIIT component on Day 1. The Burn Circuit 1 workout was challenging but doable. I had to drop the weight I used on one of the exercises because I forgot it required lifting weights to my shoulders for 10-12 reps. Other than that, my initial weight selection was good.
