Stretching, performed after exercise helps to unleash the power of the body, relax the muscles, help with circulation and muscle recovery and extend the range of movement. The Finish Line workout provides all of that without taking up too much time. Done regularly it helps increase the power output of muscles by increasing the degree of freedom in muscle motion. Add EC and you will feel a little more of the burn you need to feel, particularly if you do this after a hard workout.
Extra Credit: Do side leg raises and leg raises non-stop, no pauses.
