Workout Update: 645 Cardio/Chalean Extreme Day 5

On day 5, I did the 645 cardio routine in the morning and the Burn Circuit 3 workout in the evening. Most of the exercises in BC3 combine a shoulder exercise (a press or lateral raise) with a leg exercise. Since my shoulders are my weak area lifting-wise, I started using 10 or 12 pounds for most of the workout. For the couple of exercises in which you do two lower-body exercises at the same time, I used 20 pounds.
