Workout Update: 645 Cardio/MBF Day 9

Day 9 was the core circuit workout again in MBF and the 15-minute cardio routine from 645.

Core circuit was very similar to the week-1 version of the workout. In fact, the exercises that used the weighted jump rope were exactly the same. The core exercises were, however, switched up. The AMRAP four-minute block was also the same as week 1 (with the idea of keeping track of how you progress). This week I got through five rounds of the four exercises, which is 1.5 more than I did the first week. 

I definitely feel that my cardio fitness is improving. Adding the 645 cardio has helped a lot, as I can do moves that do not combine cardio and strength and just aim to do them faster.
