Doing exercises in the gym(健身房)
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 mbbell （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.
一些Funny Gym Stories
1.A buddy of mine uses an iPod shuffle when he works out and usually clips it to his waistband. We're working out one day and he's doing the seated leg press and next thing you know, I hear an ever increasing noise in the background, my friend screams, pushes the weight up, and promptly removes his earbuds - his love handle managed to somehow push the volume button ALL the way up on the Shuffle (there's no Hold button on it).
One time, a big muscular de was setting up to do some deadlifts. There were some ladies in the area, so of course, he stacks on more weight. On his first rep, he ripped his pants.
In general, I find it amusing how guys will attempt to lift more weight than usual when women are around. The funny thing is, the more weight you push, the more constipated you look. In fact, my wife thinks I look like I'm taking a massive mp when I'm lifting - something which, for some odd reason, she doesn't find attractive.
2.
I frequnetly go to the gym in the AM... like 445 AM! And so there are very few people at the gym at that time. Well i typically run on the treadmill on those days. Well like clockwork every day there is this strange old man that gets on the treadmill RIGHT NEXT to me! There are 20 extra open treadmills and he always picks the one right next to me. So if that isnt that funny... he also farts.. a lot. It smells sooo bad. Every step he takes he rips a fart and its just embarassing for him.
I seriously have stopped running in the morning because i was so creeped/disgusted out
3.I do treadmill races in my head with whoever is on the treadmill next to me, seeing if I can outlast them, while they're probably oblivious and just doing their own thing. One day, I'm walking to my apartment, and this guy stops me and asks me if I was in the gym that morning in green shorts. He says, "I was on the treadmill next to you, and you just kept running and running. I thought I should be able to outrun a girl, and I was trying to keep up with you for a long time, but in the end I gave up."
Totally made my day.
4.Once saw a guy at the Fitness First off Layhill Road try and flat bench 405 with no spot. Now of course he was a big de, but c'mon nobody plays around with that kind of weight sans spot. Well he did- and regretted it. My buddy and I had to pull it off of him. He then went into a whole "I could have gotten it if my shoulder was better, or my wrist." lame.
At the University of Maryland Campus Rec Center I've seen a few people bring food in. And not like a protein shaker, or the like. But Ive seen guys in between sets eating Cluck U (?).
Finally there was an older gentleman that worked out at the WSC in downtown Bethesda that my freinds and I used to refer to as "the vinegar man" because he stank like bad vinegar. f'n gross!
5.One of my friends, who is a marathon runner (that should have been my first clue), somehow convinces me to go to a spinning class with her. As I've been hearing all sorts of things about how spinning is so "in", I figure hey why not.
We get to class and I'm completely overwhelmed by how hard it is. However, my friend is next to me, and she hasn't even broken out into a sweat (we were in a beginner's class). I vow to keep up with her, even if it'll kill me.
The instructor then tells us that now that we're "warmed up", she's going to increase the resistance. And we had to reach down to turn the little resistance knobby...
...and I promptly fall off the bike.
The stationary bike.
My friend, after gasping in horror...immediately whips out her celphone and takes a picture of me and texts it to all of our friends. By the time I got home from the gym, there were 20+ messages waiting for me...all mocking...
Wah.
6.New funny gym story. i got these new shoes to wear while spinning. They clip onto the pedals and dont make my feet swell like normal shoes. So there i am about to stop and get off and my shoes got stuck. I was able to get one off but the other was stuck. So everyone in the class is laughing at me and i feel awful. I finally am able to get it out and i had to use so much force that it threw me off balance and i lost my footing and literally flew off my bike and hit my head and elbow on the bike next to me. Needless to say i will be taking a break from my spinning shoes until i figre out how to use them :P

❹ 有什么增加腰背肌力量的训练方法

从运动来锻炼腰背肌的方法：
调整腹肌的平衡
1、将双腿站开与肩同宽，双手伸直并交握于身后，慢慢吸气。
2、一边慢慢吐气，一边配合肩胛骨、头部的运动。
3、吸气，并且全身放松。
上述3步骤，反复做5次。
紧缩腰部肌肉
1、仰卧、双膝靠拢，并将膝盖弯曲成90度。双手置于头下，慢慢吸气。
2、一边慢慢吐气，一边将上半身尽量往上抬，并且保持5秒钟，将气完全吐出后，重回到“1”的姿势，重复做5次。
平卧位做腹肌运动。
脐上练习：下身固定不动，仰卧起坐，旨在使胃部凸出部分收紧平坦。
脐下练习：上身固定不动，双脚抬起做屈伸腿和头上举练习，目的是收紧和减去整个下腹围。
腹外斜肌练习：完成上下腹部练习后，再做各种腰部转体练习。这种练习作为辅助练习，使上下腹部练习的减肥效果更加明显。

锻炼背部肌肉
趴在地板上，两臂两腿尽量伸直伸长，然后两头翘：上半身最好胸部抬起，下半身要从跨部抬起（断后跨），大腿跟部要脱离地面，两边都抬的越高越好，即：身体呈现的反弓形越厉害，那么你是身体条件就越好．这个练习可以每天做三组，每组20个，每次至少在空中控制3秒注意事项：1.要尽量拉伸，即：手臂伸长，收腹，断跨，尽量绷直脚尖，用脚尖带动腿伸直伸长并且控制住（而不是用大腿的力量，那样腿会越来越粗），使身体成为一个坚实的整体2．初步开始是你的两腿也许会分开，因为这样比较容易控制住，但你要渐渐并笼双腿，并且最好把你的腿从跨部到漆盖到脚尖向外转开，上身肩膀也要转开（也就是肩胛骨尽量向后扣，颈椎骨尽量向下沉）3．大多数人很难作到腿”完全”伸直，你可以让旁人观察你的漆盖，当腿真正伸直时膝盖中间会有一个凹陷处，只有这样才是真正的用跨部和脚尖两点控制住了腿（两点固定一条线的原理），才是发挥了腰部，背部，腹部，臀部的力量4．这个练习很好的训练了腹背肌，对腰部和臀部也效果很好
劳作方式来保护腰背肌：
a、屈膝、屈髋、直腰搬重物：采用此种姿势搬重物，无需用大力伸展腰部，仅待两手握住重
物后，伸展髋及膝关节，重物即被搬起。伸展髋膝关节主要靠臀大肌及股四头肌。此两肌均较强
大，肌纤维较长，其工作效能远较短的骶棘肌为强大，因而被撕裂的机会甚小。
b、肩扛或头顶重物：肩扛或头顶重物远较搬物时省力。原因是“力臂”缩小或无，作用无垂
直，直接作用于脊柱骨，骶棘肌只需负担脊柱稳定。
c、正确的站立体位：在劳动时经常站立的较好的体位是：膝关节微屈，臀大肌轻轻收缩，自
然缩腹肌。此位置与标准站立体位相似，这样使骨盆轻微后倾，腰椎轻度变直，减少腰骶角，增加脊柱支撑力，使椎间盘不变或少受劳损。
d、坐位姿势与坐具：对于长时间坐位工作的人，则应保持或尽量不减少固有的腰椎前凸的坐位姿势，用靠椅较合适，使腰背部有所依靠,以减轻其负担。对体弱或高龄人要尽量避免低坐位姿势。
坐具以高矮合适并有适当后倾角的靠背为佳。椅的靠背以后倾100度左右为宜，高为20～25厘米，摸板宜恰好顶住腰部，其下空10～15厘米可使臀部向后移动，保持骨盆的位置（直位），以维持正常前凸。其它坐椅坐板高度以能使膝部屈曲90。～100。、两足能平放地面为宜，坐板长度以腰部按前坐定后，其前缘恰好在膝上2～3厘米，小腿能自由屈伸为宜。
e、适当的睡床：仰卧时能保持腰椎生理前凸，侧卧时不使脊柱侧弯，平板床或平板上垫较厚的垫子最好，绷紧的床次之，一般软钢丝床最差。因钢丝床在仰卧时脊柱呈孤形，易使腰部肌肉、韧带、骨关节疲劳、劳损。
F、积极治疗腰背部损伤是预防慢性腰背痛的积极措施，以免形成粘连或瘢痕。治疗腰部骨折时，要积极做好复位及腰背肌锻炼。上下楼梯对提高肌肉力量也很有效。

❻ pulley健身器材怎么用

首先说一下，跑步机的使用方法:
跑步机可以说是每一家健身房都会有的健身器材，但是往往很多人会忽视其使用注意事项。跑步机主要发展人体髋关节和腰部肌肉群的力量，增强人的心肺功能和协调能力，对舒缓压力也有明显的效果。在使用跑步机的使用，健身者双脚分开，站在左右踏板上，双手握住横杠，双腿前后交叉自然摆动。使用时必须双手握横杠，防止摔下;双腿摆动幅度不宜过大，避免肌肉拉伤。儿童使用该器械时，必须有成年人保护。非使用者不要站在器械前后，避免被器械碰伤。
第二个，腰背按摩器的使用方法:
腰部按摩器也是健身房的宠儿之一，这健身器材不仅锻炼腰、背部肌肉，而且对缓解腰、背部疲劳有非常显着的效果，对于长期坐在办公室的人来说这最好不过了。在使用腰背按摩器的时候腰部应该紧靠按摩柱，双手握扶手，上下拉动按摩柱;双腿呈马步，背靠按摩柱，双手握扶手，身体左右运动。但有的人会贪求快，所以双手运动的频率会很快，其实这是非常危险的，不仅达不到健身的效果而且还会有烧伤的危险。切记手臂运动速度不要太快，站立按摩时，双手应握紧扶手。
第三个，扭腰器的使用方法:
扭腰器在健身房中算是消耗能量较少的一种健身器材，扭腰器主要锻炼腰、髋部，增强腰部的灵活性和柔韧性。健身者只需要双手握扶手，站稳后向左、右转动，即可达到健身锻炼的效果。虽然扭腰器的使用方法相较于其他健身器材来说简单，但是不正确使用的话还是会造成腰部扭伤的危险。所以在使用扭腰器的使用速度不要太快，双手不要脱开扶手把，以免摔下。

❼ 锻炼背部肌肉的器械有哪些

男人们都比较热衷于健身。要知道，拥有一身健美的肌肉是很有吸引力的。那么如果想要练出好看的背肌应该选择哪些器械呢？又应该怎么使用呢？快来看看吧！

大家都知道，健身房里有很多锻炼的器械，而且各种器械的作用都不同。如果想锻炼自己的背部肌肉，可以选择哪些健身器械呢？分别又有哪些动作要领呢？让我们赶紧来了解一下吧！

第一种：哑铃。有一个动作是哑铃划船，是专门锻炼背部和手臂肌肉的。这个动作是先把一只手撑在横杠上和一条腿跪在上面，同时另一只手握哑铃。让身体保持平衡，然后一手举起哑铃到你尽可能举到的高度，放下再举起，重复20次以上。再交换另一只手。在这个过程中，背部不断的张弛拉伸，有效的锻炼出肌肉。

第二种：杠铃。这也是锻炼背肌必用的器材。先弯下腰，让两手抓住杠铃。再将背部挺直，深深的吸气，将杠铃提起来。一直提到腹部的位置，肩膀用力的收缩，凝聚力量。然后放回地上。再次重复10个以上，随训练进度慢慢的递增。

第三种：坐姿下拉器。坐在坐位上面，分别抓住上方的两个柄，缩紧背肌，把头顶的横杠拉到胸前的位置，保持两秒钟，再放掉。总共要重复20次以上。

第四种：引体向上的横杠。两手握住横杠，手臂比肩部稍宽，利用背阔肌收缩的作用，让身体悬空上升，与横杠齐平。再放松落地，再重复15个左右。

这些器材对锻炼背肌真的非常有效果，大家快试试吧！下一个健身达人就是你了。

❽ 锻炼背部的器材有哪些

很多健身器材都可以训练背部肌肉。一般常见的有哑铃、杠铃、单杠。
下面给你介绍一下这几种器材针对背部的常用锻炼方法：
哑铃：
俯身划船
起始姿势：屈膝，上体前倾，两臂直垂握杠，应使杠铃稍离地面。头不要低垂。
动作过程：收缩背阔肌，将上臂上拉，把杠铃尽量拉高，静止一秒钟，让杠铃徐徐下降到两臂完全伸直下垂。
呼吸方法：上拉杠铃时吸气，放下时呼气。
注意要点：上拉时要想着让主要力量来自背阔肌的收缩，而不是臀部。上拉时，腰要收紧，上体尽量不摇动，腿部用力，臀部后移，以保持平衡。如做单臂划船，另一手可撑扶在膝上或凳上。
杠铃：
直立划船
起始姿势：两脚自然开立，两手握杠，用上握法握距比肩狭（可窄到两拳在杠中央相接）。
动作过程：把杠铃徐徐向上拉起，直到横杠几乎触及颏部。静止一秒钟，让杠铃徐徐下垂到两臂完全伸直，重复再做。
呼吸方法：杠铃上拉时吸气，下垂时呼气。
注意要点：上拉时要让横杠尽量贴近身体。如握把较宽，杠铃上提时让两肘尖向上。上拉时身体不要摆动。下垂杠铃要徐徐而行，最后要让杠铃尽量下垂到可能的最低点。
单杠：
引体向上
起始姿势：两手用宽握距正握（掌心向前）单杠，两脚离地，两臂身体自然下垂伸直。
动作过程：用背阔肌的收缩力量将身体往上拉起，直到单杠触及或接近胸部。静止一秒钟，使背阔肌彻底收缩。然后逐渐放松背阔肌，让身体徐徐下降，直到回复完全下垂，重复再做。
呼吸方法：将身体往上拉时吸气，下垂时呼气。
注意要点：上拉时意念集中在背阔肌，把身体尽可能的拉高，上拉时不要让身体摆动。下垂时脚不能触及地面。可在腰上钩挂杠铃片来加重。
