Workout Update: 25 Minute Speed Train: Day 55

Day 55 was the last "real" workout of the 25-minute speed train program, which was core-cardio. This week, the workout uses the Give Me Five format. So, in each of the four blocks, you did a pre-fatigue exercise for 60 seconds and then four 40-second sets of the second exercise. I actually prefer this to doing four blocks and a burnout round, even though you do every exercise for a longer overall period of time.
