不少人都有这样的体验，经常久坐屁股会变大身材走样，但是其中的科学原理你知道吗？
Sitting down all day can lead to a flat butt because muscles are disengaged for so long that they forget how to wake up.
终日久坐会导致屁股变大，因为人的臀肌长期保持一个动作，忘记了如何恢复原状。
Officially called gluteal amnesia, doctors have seen a rise in the numbers of people who are desk bound for so long that their behinds essentially falls asleep.
这种症状的正式名称叫“臀肌失忆症”，医生们发现越来越多的人由于长期久坐而导致臀部变大无法恢复原状。
In addition to causing harm to the butt, sitting for long amounts of time can lead to other problems including poor posture, pain in the lower back, hips and knees.
久坐除了会对臀部造成伤害以外，还会导致其他诸如体姿难看、腰椎臀部和膝盖疼痛等问题。
Not working the gluteus maximus frequently can also lead to the muscle losing its tone, meaning a flat and flabby backside.
而由于没有经常使用臀大肌也会造成那里的肌肉失去弹性，从而失去你的小翘臀。
What is sleeping butt syndrome?
1、什么是臀肌失忆症？
Sleeping butt syndrome was coined by Chris Kolba, a physical therapist at Ohio State Wexner Medical Center, and refers to a combination of tight hip and weak gluteal muscles in the bottom.
臀肌失忆症是美国俄亥俄州维拉克斯医疗中心理疗师克里斯·柯尔巴创造的名词，指的是臀部很紧而臀肌又非常薄弱这样一种症状。
Kolba first recognized the problem when one of his clients came in from knee pain while training for a marathon.
一名客户因马拉松训练时膝盖疼痛来找他，那时他第一次意识到了这种问题。
Taking a deeper look at the issue, he found that the knee pain was likely caused by the gluteal muscles not functioning as efficiently as they should.
在深入了解这个问题之后，他发现膝盖疼痛是由于臀肌功能没有有效运作引起的。

2、久坐怎么会导致屁股变大？
Dan Giordano, a New York-based personal trainer of Bespoke Treatments Physical Therapy, has warned that sitting all day will make your bottom flat, flabby, and saggy.

The lack of blood flow and the slouching position that people generally sit in will do harm to muscle, causing it to slowly waste away.
人们长期久坐会导致臀部缺乏血液供应，从而对臀肌造成损伤，逐渐变废。
A startling majority of people, 90 percent, sit the wrong way, with the pelvis shifted forward which puts pressure on the spine.
而且令人惊讶的人，90%的人坐的方式都错了！他们的盆骨向前倾斜，给脊椎造成了巨大的压力。

Reversing the effects of sleeping butt syndrome and firming up a saggy posterior is possible but will take some effort.

Specific moves that will target the behind specifically include, donkey kicks, squats, deadlifts, lunges, bridges and planks.
