Workout Update: 25 Minute Speed Train: Day 10

Day 10 was the second core-cardio workout of the program. It was another challenging workout, but I would say it is more focused on core than it is on cardio. Because the breaks are extremely short, you will experience a cardio effect, but it is not comparable to a traditional cardio workout (such as those in Lift 4). This workout has three regular blocks in which you do two exercises, then a burnout block in which you do four exercises, back-to-back with no rest for 45 seconds each.
