Workout Update: 25 Minute Speed Train: Day 38

Day 38 was a total-body workout. Like the other total-body workouts in the program, this focuses more on cardio and muscular endurance, so only a few of the exercises use weights. Most of them rely solely on your body weight. And, for the couple of exercises for which you do use weight, it is a single light dumbbell. The first two blocks in the workout have a lot of squats and lunges, and the other two use more plank-based exercises.
