Qi Gong constitutes an ancient form of exercise used to generate health, balance and vitality in its practitioners; it is consequently invaluable for relieving stress. Matthew Cohen represents one of the world's foremost experts on this practice; he headlines the instructional release Matthew Cohen: Qi Gong Fire and Water, in which he primes participants on the basics of the practice with two fundamental Qi Gong exercises. The first, christened 'Fire,' emulates its titular element by imbuing the body with heat and strength, purging out toxins, relieving depression and expanding the range and scope of the five senses. The second, christened 'Water,' mirrors the effect of H2O by relaxing one's central nervous system, increasing muscular flexibility, generating inner grace and relaxation and relieving anxiety.
