I was at the car dealer for 3 hours to change tires and regular check-up so I decided to do some work with computer while waiting.

There were couture top, so I didn’t need to sit down on the chair.

After almost three hours of standing, a man came and said “you are standing whole time, why?’

I explained how I try to avoid sitting in a chair too much to maintain my core strength and good posture.

He liked my idea, and when it came time to pay for the service, he came to where I was standing and he said “I guess I don’t need to sit down so…..”

At home, I have my computer on the second shelf of desk so I can stand when working.

We sit too much.

Sitting increases stress on the body core 40 % more than standing.

座った姿勢の時は腰への負担（ストレス）が立っている時よりも４０％増加します。

立ちながら体幹を鍛え正しい姿勢を保ちましょう。
