Biology-mysteries - http://list25.com[..]manity-has-not-figured-out-yet/?view=all

Over 50 years ago, researchers circumnavigated the Americas sampling ocean life along the way at regular intervals. In the process, they discovered a striking relationship: the abundance of a certain marine species is linked to its body size such that its collective mass is basically the same. Krill are a billion times smaller than tuna, but their numbers are a billion times more abundant. If you were to weigh all the krill in the ocean, the mass should be close to all the tuna — but not anymore. - https://www.zmescience.com[..]umans-broke-a-natural-law-of-ocean-life/

*簡單的說:** **就是《氣血不通、不活絡順暢、阻塞了**....**》** *

*《就像都市裡的下水道、使用久了、淤塞了、 不通了。》*

*所以要保健膝蓋、就是要活絡這個部位的氣血**..*

*每天只要**10**分鐘、就能保健您的膝蓋:*

*1.**使用手掌拍打膝蓋的外側、內側各**2**分鐘。*

*? q這樣子就可以活絡腳上外側的膽經、胃經、以及內側的脾經、肝經、腎經〉。*

*2.**再來、拍打後膝窩的部位** 2**分鐘、〈活絡膀胱經〉。*

*3.**再搓揉膝蓋** 2 **分鐘。** **最後:跪膝** 2**分鐘。*

*貼心叮嚀** :*

*1.**一定要每天做、運動之前要先做、如果不方便做跪膝動作、那麼就拍打後膝窩**4**分鐘。*

*2.**千萬千萬不要跑步**....**有了年紀、跑步是最傷害膝蓋無知的動作、可以改用:快走的活動。*

*3.**登**山活動可以參加、但是下坡時、一定要以《整個腳板著地踩下的姿勢來走下坡路》** *

*千萬不能以腳尖先著地的踩下姿勢走下坡路段、這樣的走法、全身的重量經由腳尖全部卡在膝蓋上**!!*

*也就是說:你是以膝蓋來支撐下坡時全身的重量。*

10個令腿粗的原因:

10步骤让大粗腿立刻变细腿

腿粗原因

 1。飯後經常坐

 2。喜歡翹腳

 3。不喜歡做運動或討厭走路的人

4。站一整天后沒有適時按摩小腿

 5。每天用淋浴洗澡

 6。愛喝凍飲

7。常穿不合腳的鞋走路

 8。喜歡吃濃味食物

9。站姿不正確,例如側重一邊

10。有便秘困擾

這是糾正你的壞習慣的好方法!

10步骤让大粗腿立刻变细腿

糾正你的壞習慣

1。良好的生活習慣是基礎,更搭配合理的早餐,能讓你一天都精神充沛,幹勁十足。

2。踝關節,膝關節,股關節都要用力才是正確的走路方法,這也是打造美腿的關鍵了。

3。在搭乘電車時,正好可以為肌肉做牽拉運動,堅持一段時間後,就能出現明顯的效果了

4。有效的散步,這是最簡單有效的燃脂有氧運動了,要點是:首先走姿一定要正確,其次時間要長。

5。保持正確的坐姿,雙腿靠攏,背部挺直,養成良好的習慣後,慢慢你就會發現這樣坐姿會令身資變得更加挺拔。

6。伸展運動,長久坐或站時,要適時地伸展一下肢體,讓肌肉和關節放鬆一下,對美體很有功效哦!

7。每天舒適的泡澡,每日泡澡非常有益健康哦。這樣不僅可以消除疲勞,還能加速新陳代謝,起到減肥功效。

 8。腿部的按摩,另外告訴你一個小貼示:在泡過澡後進行腿部按摩可以消除浮腫,而且會事半功倍哦!
