Workout Update: 645 Cardio/Lift 4 Day 15

Day 15 was the start of week 3, which means increasing the amount of weight on the Lift 4 exercises. This was the chest and triceps workout, which is a 50/50 workout in week 3. I used the microplate magnets to add weight to my metal dumbbells, which was all I needed for most of the exercises to make them more challenging. I chose very low-impact exercises in the 645 cardio workout since the Lift 4 workout had the HIIT component.  That worked out well.
