Workout Update: 25 Minute Speed Train: Day 17

 Day 17 was the core cardio day for week 3. It has a very similar format to the workouts from weeks 1 and 2. You alternate between a plank (or bear stance) exercise to a core exercise. So, the entire workout is on the floor. You do need light weights for a couple of the core exercises. There are four regular blocks and then a burnout block where you do four of the eight exercises from the regular blocks of work for 45 seconds each with no rest between them. While the workout is hard, I can definitely tell I am getting stronger as I can do more of the plank-based exercises on my toes than I could in weeks 1 and 2.
