律动与外丹功的分别
外丹功和全身垂直律动的原理都是让身体在自然频率弹抖， 让全身处于放松状态。 在弹抖的作用下， 全身的每处细微部分都在抖动，血管易于扩张，血液自然加速运行，而微循环随之增强。
两者不同点在于， 外丹功需要靠自身的力量弹抖，而且需较长时间的练习， 才能达到自然动抖及弹抖频率一致的状态。 而全身垂直律动则是靠机械发力， 让身体在同一频率下自然抖动。
外丹功利用「吐」与「纳」的自然呼吸作用的方式与肢体的配合，来达到全身气血通畅。外丹功总共有十二式，视练功功龄深浅而定，招式可在30分钟至60分钟内完成。弹抖动作配合节奏的呼吸，可使人体保持肌肉松弛，呼吸平顺，血管易于扩张，血液自然加速运行，而微循环随之增强，身体的供氧量充足。经过约数十分钟的弹抖动作之后，整个人便觉身轻气爽。
全身垂直律动与外丹功于发功后所产生的和谐共振频率是有异曲同工之妙的。所以外丹功其实与全身垂直律动，有其相同与不谋而合之处。都可以促进血液的循环，以供应身体各部分充分的氧气与滋养，使脏腑正常运作，实是增进健康的基本条件与法则，达到健美健康的目的。
而全身垂直律动就是透过地心引力的物理上下的快速频率震动，对于身体产生一种特殊型态的冲击，改变身体的肌肉骨骼神经系统，更进一步影响内分泌及其他生理系统，以产生各种有益健康的效果。全身垂直律动无需练习招数，也无需深厚的练功功，只需站在全身律动仪上15分钟，就能达到外丹功的效果。
The Difference between Vibration and Wai Dan Gong
The difference between the two is that Wai Dan Gong needs to bounce by its own strength, and it takes a long time to practice in order to achieve a state of natural shaking and consistent shaking frequency. The Whole Body Vertical Vibration(WBVV) depends on mechanical force, which makes the body shake naturally at the same frequency.
Wai Dan Gong uses the natural breathing methods Tortoise Breath- "exhale" and "inhale" to cooperate with the limbs to achieve smooth Qi-blood circulation throughout the body. There is a total of twelve types of Wai Dan Gong, depending on the level. The moves can be completed within 30 to 60 minutes. Bounce and shake for rhythmic breathing can relax the body, breathe smoothly, blood vessels are easy to expand, blood naturally accelerates, and microcirculation is enhanced, and the body's oxygen supply is sufficient. After about ten minutes, one will feel the whole body felt refreshed.
The Whole Body Vertical Vibration(WBVV) and the harmonious resonant frequencyproduced by the Wai Dan Gong after the exercise are similar. So, Wai Dan Gong is similar with whole body vertical vibration. Both can promote blood circulation to supply sufficient oxygen and nourishment to all parts of the body, so that the organs can function normally. In fact, it is the basic conditions and rules for improving health and achieving the purpose of bodybuilding and health.
The Whole Body Vertical Vibration(WBVV) is the rapid up-down frequency vibration through gravity, which produces a special type of impact on the body, changes the musculoskeletal nervous system of the body, and further affects the endocrine and other physiological systems to produce a variety of efficacies. The Whole Body Vertical Vibration(WBVV) does not require any tips nor does it require tense practice. All you need is to just stand on the Whole Body Vertical Vibration(WBVV) machine for 15 minutes, you can achieve the effect of Wai Dan Gong.
