弯举技术 让肱二头肌更抢眼

[fhhuo6059]

其实，无论初习者还是有一定训练年限的“老手”，拥有令人羡慕的肱二头肌始终是他们的追求与梦想，并为此一 直不懈努力。那么，发达肱二头肌究竟有哪些较为有效的方法，技术特点和需要注意的细节又是什么 呢
肱二头肌理想的形态是：直臂状态下侧视，其下端一直长达臂弯。弯曲时，呈半球状明显隆起(施瓦辛格和冈特的 肱二头肌呈抛物线状，如停留在胳膊上的两座高耸的山峰)。这种理想形态对于先天长条形的训练者来说，可谓得 天独厚。但拥有这种形态的人极少，大部分人侧视时臂弯处都有一个或大或小的缺口。所以，应针对性地优先刺激 肱二头肌的下端部分，这样才能获得较为理想的上臂形态
下面介绍各类弯举动作的细节要点。
一、杠铃弯举
1、立姿直杠弯举
站立，双手同肩宽握杠，自然速度弯举，时间1～2秒：下放时控制还原，时间3～4秒。上举时注意力应集中在 整个肱二头肌上，想象并排的两条肌束如钢绳般收缩。如果想尽快使肱二头肌下端发展起来，则应将注意力和起动 点均放在此处。还有、杠铃下放到底部时要有意识地伸直胳膊。如果屈臂，则难于刺激到嵌入肘弯的肱二头肌下端 .这是很多健身者不太注意的地方，只要做标准次数(8～12次/组)，都应刻意伸直胳膊，但8次以下(承重较大)为避免肘关节和肌腱无谓受伤，应保持胳膊自然 的屈伸度。
常规重量组为每组10～12次至力竭，做3～5组。上身应保持正直，不要靠晃动身体借力，这对初练者最合适 。系统训练半年以上者，应采用变速组或爆发式上举。实践证明，只要采用逐加重量的方法充分热身(至少2组， 一般是3组)，使肌肉和神经系统进入训练状态，同时注意力高度集中在目标肌上，用适宜的重量(8次左右)做 变速或爆发式弯举就不会产生伤害事故。中、高级水平者应在正式组的第3或第4序列将试举次数降 至6～8次/组或4～6次/组，然后再回升到正常训练次数。这样既能调动更多的肌纤维参与运动，又能保证足够的训练量，使目标肌更好的 充血膨胀。变速组是指将一个训练组分为前、后两个半程，两个半程的上举速度和还原速度有较明显的区别，从而 使肌肉受到更强烈的刺激。
这个动作的主要作用是全面增大肱二头肌的厚度与块头，另外，可通过握距的变化重点刺激内外两个肌束：宽于肩 部的握距对肱二头肌外束刺激较大，略窄于肩的握距对内束刺激较好、可根据个人情况侧重采用。
2、曲杠弯举
站立，双手执杠做弯举。由于是曲杠，小臂不像直杠那样紧张，参与用力较少，可保证更多的负荷加在肱二头肌上 。
曲杠弯举的效果有争议，部分训练者认为效果不如直杠，主要是施加在肱二头肌上的张力不明显。
曲杠由于角度基本符合自然状态下手臂的内旋状态，肌肉感觉较舒适。直杠迫使双小臂呈一定的外旋角度，上臂和 小臂肌肉都有一定的紧张度，对抗负荷做动作时更明显，故感到张力效果十分明显,盟特新奇特批发。且无论上举还是下放都能保持持续紧张，使目标肌没有多少“喘息”机会，这种紧张度的存在使直杠弯举在发展 肱二头肌的同时，对小臂也有一定促进作用，这是曲杠难于比拟的地方。从肱二头肌承担的负荷来看，曲杠由于小 臂参与用力少，若重量相同，则承担的负荷大于直杠，对肱二头肌的刺激作用更大些，但在肌肉的持续紧张度上逊 于直杠，特别是在杠铃下放阶段。由于角度适宜。对腕部不适或有伤者，曲杠则是代替直杠弯举的好 方法。
训练要求与立姿直杠弯举基本相同，注意力应集中在整个肱二头肌上，标准的训练安排是：12、10、8、6、 10次，做5个正式组，其中孤立重量组(10～12次/组)必须保证做3组，较高次数与较低次数的合理搭配，既能保证调动更多的肌纤维参与运动，又能保证动作的规 格与次数，利于产生“泵”感的充血效应，
二、哑铃弯举
1、坐姿哑巴铃交替弯举
坐于凳端，双手各执一哑铃，左右交替做弯举动作。
弯举时为保证动作的准确性，可采用对镜训练方式。这样可纠正低头助力的毛病。
为了让肱二头肌弧度更饱满、肌肉更厚实，应做“均衡弯举”，哑铃尽量保持水平，不要左右晃动，使肱二头肌的 内外两个肌束均匀受力;若为打造肱二头肌的尖峰。则须有意识地外旋小臂，仿佛要用小指去触碰肩膀。另外，可 用一个小技巧来修饰上臂形态，兼顾肱二头肌下端;这就是在哑铃下放至底部时有一个自然后撤动作，幅度不大， 但能令胳膊彻底伸直。然后以肱二头肌下端为起动点(意念也集中于此)，带动哑铃弯举。次数变化在每组10～ 12次之间，下限不要低于8次，否则难以保证动作的规范。
为打破适应性，接受不同的刺激频度，有时可安排连续试举，一般是安排从重至轻的不同重量，而不是反向顺序。 这更符合肱二头肌的耐受特点，也更容易挖掘其生长潜力，同时可避免拉伤肌腱。例如，以25公斤的哑铃弯举至 力竭后(10～12次左右)，紧接着试举20公斤的哑铃，无法再完成一次时立即接做15公斤的哑铃至力竭。 这样重量呈现2～3个阶梯，但至多不要超过3个，每个阶梯重量相差5公斤左右，过大过小都会影响进一步挖掘 肌肉潜力，影响训练的综合效果。
2、哑铃斜板交替弯举
坐在后倾角为45度的斜板上，双手各执哑铃做交替弯举。
第一组的重量不要过大，目的是热身、确定动作路线和感觉，然后再逐加重量。正式组为5组，第3、4组可加至 最大负重，次数为6～8次。
这种后倾角度能使肱二头肌上缘与肩部交接的肌腱处始终处于牵拉的紧张状态，利于发展肱二头肌上部。由于无法 像普通状态那样“夹肘”，下放时手臂的后展和上举过程的转腕动作对肱二头肌的下缘与尖峰都有一定的刺激作用 。所以这是一个较全面锻炼肱二头肌的动作，也是健美巨星施瓦辛格极偏爱的一个必练课目。
由于这个动作的“支持性”较差，故整个动作过程应全神贯注。必须均匀发力,盟特新奇特产品，下落也应如此。上升至顶部时做顶峰收缩2～3秒钟效果会更好。
3、单臂哑铃斜托弯举
杠铃斜托弯举的目的是为了刺激肱二头肌的下端,盟特新奇特，所以下放至底部时双臂必须有意识地伸直，否则就失去了动作的意义、单臂哑铃斜托弯举不具备双臂执握的稳定 性，对关节和肌腱的要求也较高，训练的目的主要是通过肌肉的持续紧张给肱二头肌以集中刺激。
动作的细节要求是：一手扶凳，以提供稳固的支撑，持铃臂的伸展不要太充分,加湿器价格，以免给关节带来不必要的麻烦，不要尝试做顶峰收缩(会很别扭，找不到通常的训练感觉)，也无需刻意伸直胳 膊，这样才能让肱二头肌保持持续紧张状态，达到较好的训练要求。
另外，由于单手执握依托凳面，没有任何借力机会，故采用的重量也应谨慎。仍然是5个正式训练组，第1组采用 较高的次数，然后逐增重量。标准的训练安排是：15、12、10、8、6次，这更符合动作的特 点和要求。
三、牵拉类动作
牵拉类动作的特点有二：一是超常的持续紧张状态;二是为了对抗负荷和保持动作的稳定性，肌肉要承受强大的张 力。
比较有效的动作是：
1、单械徒手(或负重)引体向上
掌心向内反握杠，注意力完全集中在肱二头肌上。拉起时要以肱二头肌的收缩力带动身体移动，下放时必须做到控 制还原，保持身体稳定，缓慢降至最低位，不要顺势而下，否则得不到负功收缩的效益，肌纤维也得不到拉伸的张 力，这正是引体向上训练的关键之处——拉伸使肌纤维产生的有益损伤(相比屈伸类动作，拉伸使肌纤维的有益损 伤更显著)使肌纤维在获得充足营养和休息的情况下，能更好的超量恢复，体积和力量增长更明显。
一旦能徒于完成10～12次/组，就应在腰部挂杠铃片，使每组次数降至6～8个，若又做能到8个以上，则应再增加铃片重量，使之回归到6 个左右。中高级水平者也可通过每组4次以下的低次数针对性地发展力量，以挖掘更大的潜力，使基础训练的负重 得到提高，也相应提高了训练强度。
标准的训练安排是：12、12、10、8、6次，共做5组。关面2组12次为徒手动作，后3组逐增负重，这 样总的组次数和强度都有了保证
2、拉力器直杠弯举
立于十字拉力器架一侧，调节好拉力器长度。然后进行弯举、
先进行1～2组的轻负重练习，以确定一下线路及动作感觉，然后再逐步加大重量。
拉力器弯举的最大优势在于：施加在肱二头肌上的压力不会因动作角度而变小，张力效果非常明显。所以提倡下降 时刻意控制动作，与铁块配重相抗。上升时速度应较快，也可用爆发力，但必须在充分热身后，且注意力必须高度 集中在目标肌上、
我喜欢将注意力完全集中在肱二头肌下端，以此发力带动整个弯举动作.做爆发式弯举。至顶部时停留1～2秒， 做顶峰收缩，然后控制性还原，上臂形态因此获益匪浅。
3～5个正式组，逐加重量，次数为15、12、10、8、6。如果体力下降，也可只做3组高次数组，以肱二 头的“泵”感为主要训练目的。
一般而言，拉力器弯举应安排在杠、哑铃弯举之后.偶尔(10～15天左右)也可倒过来，给肌肉一个“冷不防 ”，以激发其活力，打破刚刚建立的动作定型。
除上述动作外，还有反向布道凳弯举、固臂板弯举、顶肘式弯举、俯姿哑铃集中弯举等动作，可做为训练的替代或 补充。但不要为了追求动作形式的变化而采用一些看似花哨实则有害的弯举动作，如平肘式弯举(胳膊平放在凳面 上)、倒地(卧姿)拉力器直杠弯举等等。这样，我们就可以在掌握尽可能多的训练手段的同时，避开不必要的动 作伤害，稳妥地取得一个个实质性的进步，使健美的臂膀成为你倍感骄傲的风景。

A tree grows to the wall, the ancestral temple of the walls are bursting.
a snake the size of the tree as

Yiwu has trees, Cheng rebellion to the reader: Niansanli Town in Yiwu City, Tao chomchon, there is a tree which grows on the wall, and then from the roof to wear out. This house is unhistorical buildings, trees now grow up, to support the walls cracked.

reporter on the scene saw the tree on the long wall in the shrine's courtyard was the place cracked bricks scattered support the floor. The tree, like the Earlier, the crown has been sawed off the villagers from afar, as if the tree stands as a telephone pole. Although it is late autumn, but still a long tree trunk with a few leaves, revealing a very strong vitality.
discussion of this uncommon.
Villagers told reporters that any big sister, this is a Paulownia tree, long in the shrine's roof has been for years. At 14:00 on October 30,true religion outlet, she was still in the house taking a nap when he heard

Starsky polygraph experts,cheap true religion, forensic experts, Jin Dengwei Detailed Provincial Public Security Code

polygraph lie detector code

■ polygraph does not reflect the lies, but test the truth

■ The more educated people, lie the more easily measured out

■ polygraph subjects who do not understand the principle, the result is not satisfactory

■ Polygraph results not as evidence in the case, but supporting

■ polygraph is not always right!
he is not a murderer? Did he lie? Through a special set of questions and answers, the polygraph can be your body's reaction to find out. What this means, how to work the machine in the end? Yesterday, the Provincial Public Security Criminal Technology Division Chief, Jin Dengwei pan one by one for journalists to explain its mysteries. However, in these stories lie detector, the most impress you might not be that expensive machine,true religion skinny jeans, but with experience of police officers trained in psychological Running out of capacity - and sometimes, his psychological analysis, more accurate than the machine!
polygraph Code >>>

first to object to do quite particular - need to do a little test, so that any object to write a number, then asked him to write is not the number. If the person on the issues raised by examiners, respond in order to do lie detector tests, which do first if skin test prior to injection. Let us also to
test multiple body

start a lie detector, the object sitting in a chair with armrests (which can make users mental relaxation), the face of white walls (which can make the subjects elimination of the distractions), the complete set of equipment worn on his chest, abdomen, arms, fingers and other four sites (detected on the body, respectively). Examiners,levis jeans online, sat the object side of the observations from the computer.
Except for measuring the truth lies

ready, the polygraph examiner asked: is If the object is written, 3, and 3 every time he asked, the curve will be increased. It is useful to note polygraph, but if he is the response of each figure are the same height of the curve are the same, then prove that this person does not respond to the instrument.
It can be seen, the polygraph is in fact not a response to the lies, but rather a response to the truth. The polygraph also many ways according to this Q & A - the examiners,true religion sale, to your question, you answer.
culture, the higher the better identification

were unexpected conclusion - a test of the more higher level of education play a role. May also be why, in each of the lie detector test object, we need to tell people the principles of the instrument, let him understand what features of the instrument, how it is, and then start the test, since he did not understand the principle of this instrument,true religion shop, test out the effect is not ideal. murder, President should be asked to find out exactly what the police, has aroused suspicion of the police, but could not conclude that very fact is the killing of her husband's murderer.
So Jindeng Wei Ning Huijun and partner psychological test instrument carrying singled out this woman came to the scene. First, the very fact that the personal circumstances of the case and a certain understanding, Jin Dengwei start the test.
then 2 times the test results are also consistent with this, so Jin Dengwei found: Although not sure whether she was killed, but at least prove that very fact is very suspect. With the test results, with detection of the direction of police investigators in the trial increased the intensity,true religion straight, the very fact that in just a few hours later, I honestly confessed: she and her lover conspired to cheat her husband out of their strangled in the car, and then postmortem roadside.
polygraph machine >>>

98% accuracy the details of the body will betray you

Provincial Public Security Bureau Criminal Technology Division pan Chief Jindeng Wei is the first batch of examiners, the province since 1999, the introduction of polygraph technology in Sichuan, he began with the psychological liar Running out of history.
11 years, he traveled with the whole apparatus of Sichuan, do not remember how many pieces of the case, measuring the number of individuals, just remember that the test results are accurate 98%.
standard polygraph machine really so? Jindeng Wei's no doubt from the truth. Person's mouth can lie, but the body does not lie. Not only a new generation of polygraphs to make judgments from the heart how fast it can from several parts of the upper and lower body movements to make comprehensive judgments, these areas include the hip action, blood volume, skin and other fingers the ########## eye can not detect part.
Therefore, even if the liar is difficult to escape the polygraph intentionally concealed the palm. Polygraph can not directly solve the case, but it can provide real answers to handling units of the direction of the imposition of psychological pressure on the test - let him explain earlier.
polygraph highest level >>>

polygraph not sure when I have the final say

, polygraph tests are not 100% accurate, it is necessary to rely on comprehensive analysis of police.
2008, the Meishan manager of a company car on company laptops stolen containing information on the company's internal and customer information, are secret documents, valuable. Survey, the manager reflects a clue to the police: a man named Wang Qiang had his men (a pseudonym) of the employee money to help him buy a computer, which also by the staff of the paper back to the new computer. Wang Qiang, also specifically requested not let other people know. Is the employee stole a computer reselling company secrets - he was very suspicious.
psychological tests conducted since then the results also showed that - although not directly measured by Wang Qiang, the crime of telling the truth, but he could not rule out the suspect in that case. Get the results, Wang Qiang, was nearly as suspect. Jin Dengwei until his sentence to be reconsidered. is impossible to say so, and can not be interested in the World Cup - because his heart had more fear, and stress.
few days later, Meishan, a special police Danghuo goods vehicle theft gang, and that the company's computer was stolen by this gang is. At this point, we came to the understanding, Wang actually did was to prevent managers are suspected of lying.
