Workout Update: 645 Cardio/Lift 4 Hybrid: Day 50

Day 50 was the legs 50/50 workout in Lift 4 and the 645 cardio workout. Both of them went well, but I did still have to modify some of the HIIT exercises in the Lift 4 workout. I can tell that I am getting stronger and that my cardio is getting better, but I still have a long way to go.
