The pressing down of palms should be coordinated with the bending of knees generic vasotec 5mg without a prescription. This breathing method should be applied in all the forms of this exercise order vasotec 5mg online. Visualization: Imagine yourself rising and falling smoothly like the water shooting from a fountain generic vasotec 5mg visa. Effects: The rise and fall of the body helps activate the flow of Qi discount vasotec 5mg without a prescription, unblock the energy passages and regulate Qi and blood. It is good for ailments such as high blood pres- sure, heart disease, and hepatitis. Those suffering from these ailments can do this form as a separate exercise, in which the movements may be performed as many times as suits the condition of the individual. Lift both arms forward to chest level, while inhaling, with palms facing down- ward, then turn your palms so that the thumbs point upward before moving arms horizontally to the sides to expand chest and continuing the inhale [Photo 4]. Exhale and bring hands toward each other and turn palms downward when they are held in front of your chest. TLFeBOOK Q igong E xercises / 75 Points for Attention: Straighten up gradually as you lift arms in front of chest, and bend knees slightly as you press palms downward. These movements should be performed with continuity and co- ordinated with breathing. Visualization: Imagine yourself standing on the top of a high mountain and looking far into the distance with a tranquil mind. Effects: Good for pulmonary emphysema, heart disease, shortness of breath, palpitation, chest distress, neurasthenia, and neurosis. Start inhaling as you slowly straighten knees and lift arms up to chest level with palms facing down. Keep inhaling as you do the following movements: Move arms up overhead while shifting weight onto right foot with right knee slightly bent, left leg straightened and turned 90 degrees outward to the left; then, lower left arm parallel to the floor on the left side with palm up [Photo 5]. While exhaling, the bent right arm will now paint a rainbow, or move in a circular fashion overhead and to the stationary left palm. When the palms are 3 inches apart, both hands form a ball or circular- holding shape [Photo 6] and continue down to in front of the abdomen. The weight has remained on the bent right leg until the hands reach the abdomen, then the left foot turns back to the front position, the weight is centered on both legs, and the hands begin the same movement again as Step 1, this time to the opposite side [Photos 7 and 8]. TLFeBOOK Q igong E xercises / 77 Points for Attention: The painting of the arms should be gracefully coordinated with breathing and with the lifting of the arms. Effects: This form helps take off fat from the midsection and is good for backache and kidney diseases. Lower both arms and cross hands in front of lower abdomen, palms facing inward [Photo 9]. Inhale as the arms pivot upward, keeping the palms facing your body, until the hands are overhead [Photo 10]. Exhale and turn the wrists so that the palms now face outward (backs of hands are facing each other) [Photo 11] and move the arms outward and downward in a gentle arc [Photo 12]. Continue the downward motion until the hands are once again crossed in front of the lower abdomen. Points for Attention: Use shoulder joints as rotational points when you swing arms up, lifting chin slightly and expanding the chest as you inhale. Visualization: Imagine yourself thrusting your hands into the clouds, then grabbing the edges of the hole that you made and pulling the clouds apart. Effects: This form helps generate Qi and build up strength in the waist and legs, and is good for heart disease, shortness of breath, and periarthritis of the shoulder. TLFeBOOK Q igong E xercises / 79 Form 5 Whirling Arms on Horseback (*Plate of Spaghetti) 1. With feet remaining in normal stance (shoulder-width), inhale; lift both hands up to shoulder level in front of the body, palms facing downward. Still inhaling, shift the weight to the right leg, bending the right knee, and bring the right hand up to the right shoulder, fingers facing backward and palm facing up. Still inhaling, extend the left arm to the left, with a slight bend in the elbow, fingers pointing to the left and palm up.
