Workout Update: 25 Minute Speed Train: Day 20

Day 20 was a total body workout consisting of four blocks. Each block contained two exercises, some of which used weight and some did not. There were also some unbalanced exercises in which you worked one side of the body, then the other. The main muscle groups worked today were legs, back, shoulders, biceps, and chest. And, like the other workouts, because you have very little rest in between the sets, you are getting a slight cardio effect as well.
