Doingexercisesinthegym

　　usually i would do some exercises on the weekend，because i thought keeping  in a good health can help me study well. last weekend, it was rainning outside so i decided to do some exercises in the gym. when i went into the gym, some people were doing exercises there. a man was doing weight training and trying his best to upraise heavier weight. there were two girls running on the treadmill（跑步机），neither too fast nor too slow. in the next room there was a  fitness instructor(健身教练) was teaching some young people doing yoga（瑜珈）, which made they do some strange actions.

　　after some minutes' warm up (热身)，i started to run on the treadmill and ride on the exercise bike（健身脚踏车）. both of them were easy and good for most of people. besides，i did some dumbbell （哑铃）exercises ,seating type chest pushing, high pulling force back muscle training, butterfly clamp chest muscle training, thigh stretching, leg treading, abdomen muscle training, vertical pulling force training.  (坐式推胸、高拉力背肌训练、蝴蝶夹胸肌训练、大腿伸展、蹬腿、腹肌训练、直立式拉力训练)

　　finally，i cooled down myself and had a break before i went home.
