A very simple - yet perhaps one of the most effective - cooldown session comprises an ancient yoga asana (posture). The shavasana, known in English as the "corpse pose", is exactly as the name suggests it to be. All it involves is literally just lying down flat on your back and breathing easy. The corpse pose brings to life the old Zen philosophy of "activity in inactivity".
This short session does wonders in regulating recovery and normalizing the system, especially after strenuous physical activity. This is also a great way to unwind after a hard day's work. Remember: important as it is to work the human body, rest and recovery is an equally important contributor towards maintaining good health and optimal fitness.
