Workout Update: 645 Cardio/Lift 4 Day 16

Day 16 was the back and biceps circuit workout from Lift 4 and 645 cardio. Again, I mostly used the microplates to add 2.5 lbs to most of the exercises, which was a good way to increase weight while maintaining proper form. In the 645 workout, I chose more intense exercises since there was no HIIT in the Lift 4 workout.
