Q & A
为什么在进行二头肌训练时,避免使用过重的重量很重要?
-使用过重的重量可能导致身体通过摇摆来作弊,这样虽然可以使用更重的重量,但并不会增加对二头肌的张力,反而会给下背部带来额外的压力。
如何避免在二头肌训练中使用过多的动量?
-可以通过将背部靠墙站立来防止身体摇摆,这样可以减少动量的使用,并确保二头肌得到更有效的锻炼。
为什么在二头肌训练中不应该缩短动作范围?
-研究表明,当肌肉完全伸展时,尤其是在动作的底部部分,可以为肌肉增长提供强大的刺激,特别是在肌肉的远端区域,如二头肌的下部。
为什么在二头肌训练中手腕的位置很重要?
-如果手腕在卷曲时弯曲,会导致前臂肌肉过度参与,从而减少了二头肌的激活,并且可能导致前臂疲劳和抽筋。正确的手腕位置应该是与前臂对齐,以减少前臂的参与。
为什么在二头肌训练中保持肘部锁定很重要?
-如果使用过重的重量,前三角肌会帮助举起重量,导致肘部向前移动,这称为肩部屈曲。这会减少二头肌的激活,而更多地激活前三角肌,与训练目标相反。
如何通过心理技巧来增强二头肌的训练效果?
-2018年的一项研究表明,专注于挤压二头肌并感受肌肉工作的那一组,在八周后几乎获得了双倍的二头肌增长。即使有正确的姿势,尝试感受二头肌的收缩也很重要。
在进行二头肌训练时,如何更好地激活二头肌?
-可以通过想象将杠铃或哑铃拉向身体,并在卷曲时将小指推向天花板,就像是尝试向外旋转手一样,这样可以强调二头肌的另一个功能——旋后,有助于获得更强的收缩。
为什么不应该只做部分范围的动作,比如只做二头肌训练的底部一半?
-尽管研究表明只做部分范围的动作可以刺激特定肌肉区域的增长,但为了全面地锻炼肌肉并避免不平衡的发展,推荐进行全程的动作。
如何通过科学的方法找到最适合自己的训练计划?
-可以通过访问builtwithscience.com并完成分析测验来找到基于科学的、适合自己身体条件的定制训练计划。
在二头肌训练中,为什么不应该忽视小细节?
-小细节,如手腕的位置、肘部的锁定、动作范围的完整性等,都对肌肉的激活和训练效果有重要影响。正确的形式可以最大化肌肉的激活,提高训练效率。
如果感觉不到二头肌的收缩,应该怎么办?
-可以尝试将手臂放在身体两侧,尽可能用力地弯曲二头肌,然后将手臂举到面前再次弯曲,在这个位置你应该能感觉到非常强烈的二头肌收缩。
为什么在二头肌训练中要避免使用过重的重量?
-使用过重的重量可能会导致身体其他部位,如前三角肌和下背部,参与到本应由二头肌完成的动作中,从而减少了二头肌的激活和训练效果。

💪 錯誤和技巧:增強二頭肌訓練效果
這段文字主要探討了在進行二頭肌卷曲訓練時常見的五個錯誤,並提出了改進建議。首先,討論了使用過重的啞鈴導致用力過猛,從而借助於身體的擺動來完成動作,這實際上增加了下背部的負擔而非二頭肌。建議使用牆壁來限制身體擺動,並使用適當的重量來保證動作的正確性。其次,介紹了兩項研究來解釋為何動作的下半部分(肌肉拉伸最大的部分)對於肌肉生長特別有效,建議在訓練時不應該忽視這一部分。最後,指出了許多人在做卷曲動作時手腕位置不正確,導致前臂過度勞累,建議調整手腕位置以減輕前臂的壓力並更有效地刺激二頭肌。
🏋️♂️ 進階技巧:最大化二頭肌卷曲效果
本段講解了如何通過注意肌肉的感受和動作的細節來提高二頭肌訓練的效果。首先,描述了一項研究,顯示在訓練中專注於肌肉的感受可以顯著提高肌肉增長。提供了一個練習技巧來加強對二頭肌收縮的感受,即在不同的位置對二頭肌進行強力收縮,以體會強烈的肌肉收縮感。接著,建議在進行卷曲動作時想象將啞鈴或杠鈴拉向身體,同時將小指向上旋轉以加強旋前肌的刺激,這將幫助實現更強的肌肉收縮。最後,強調了全面關注訓練動作的每一個細節的重要性,不僅僅是二頭肌,這對於達到最佳的訓練效果至關重要。

Highlights
二头肌训练并不复杂,尽管有多种不同的练习,但它们基本上都归结为一个动作:卷曲。
几乎每个人都会在做二头肌卷曲时犯五个常见错误,修正这些错误可以显著提高训练效果。
当你卷曲重量时,会发现它变得越来越难,但在肘部达到90度后,难度又会降低。
轻微的摆动可以使锻炼变得更容易,但也可能导致额外的负荷转移到下背部。
为了减少摆动,可以靠墙做卷曲,以防止身体摆动。
一项研究发现,仅做卷曲的下半部分可以促进二头肌增长,尤其是二头肌的下半部分。
另一项类似的研究显示,仅做腿伸展的下半部分可以显著增加大腿四头肌的增长。
训练时不应缩短动作范围,特别是在肌肉完全伸展的位置。
腕部位置错误可能导致前臂肌肉过度参与,减少二头肌的激活。
正确的腕部姿势是保持与前臂对齐,这样可以减少前臂的参与,增加二头肌的激活。
使用过重的重量可能导致三角肌前部参与过多,减少二头肌的激活。

biceps training is not complicated
although there are tons of different
exercises they pretty much all boil down
to one movement curls hold the weight
Flex the arm simple right not really
there's five common mistakes almost
everyone makes fix these and your curls
will instantly become far more effective
at growing your biceps mistake number
one you might have already noticed that
as you curl a weight up it gets harder
and harder and becomes the most
difficult Midway when your elbow is at
90 degrees after this point it actually
gets easier and your body can sense this
and it finds ways for you to cheat
through this difficult bottom half of
the movement without you even realizing
one way it does that is by initiating
each rep with a slight swing I'm sure
we've all seen guys in the gym who take
this to the extreme but even just a
slight swing at this bottom position can
make the exercise much easier and enable
you to use heavier weights the problem
with that however is although you're
able to use heavier weight it doesn't
result in more tension to your bicep
that additional load goes straight to
your lower back which is now helping you
get the weight up by using momentum in
fact next time you're in the gym try
doing a standard set of curls with your
regular form then stand with your back
against the wall to prevent your body
from swinging at all if you had to drop
the weight considerably then it means
that you've likely been incorporating
too much momentum into your regular
curls although I wouldn't recommend
doing all your curls against the wall
you'll see far better biceps growth and
reduce your risk of injury if you simply
lighten the weight and minimize the
amount of Swing you use especially
towards the end of your set when the
Reps start to get really tough for the
next mistake I want you to take a look
at two really interesting studies one
study published just last year had
subjects perform the preacher curl but
under two different conditions one group
performed only the bottom half of the
curl and the other group performed only
the top half of the curl using a weight
that matched their strength level in
each position the biceps of each
subjects were measured at three points
after five weeks here's what happened
the group that formed only the bottom
half experienced roughly 2.6 times more
biceps growth when average across the
measurement sites however what's
interesting is that most of this growth
occurred at the third measurement site
located towards the bottom of the biceps
now what makes this really interesting
is that another study also published
just last year replicated an almost
identical design not on the biceps but
this time on the leg muscles they had
subjects perform the bottom versus the
top half of leg extensions and one more
group who did the full range of motion
they measured the growth of the Quad
muscles at four different sites after 12
weeks here's what they found for the
measurement site closest to the top of
the quads growth was similar across the
groups however as you got further and
further down the quads growth became
significantly greater for the group who
only performed the bottom half of the
leg extension even greater than the
group who performed full range of motion
groups so what does this all mean well I
wouldn't recommend doing only partial
rest from now on but it does seem that
the bottom part of an exercise when the
muscle is fully stretched provides a
powerful stimulus for growth especially
in the distal regions of a muscle like
the bottom part of your biceps so
whenever you do your curls avoid cutting
the range of motion short at the bottom
position instead extend your arm fully
by flexing your triceps at that bottom
position before you go into your next
rep to ensure your biceps get fully
stretched I remember for the longest
time whenever I would do curls I'd end
up feeling it way more on my forearms
than in my biceps in some cases I'd even
have to stop my sets not because my
biceps failed but because my forearms
just couldn't handle holding the weight
any longer the reason for this had to do
with my wrist position the function of
the inside forearm muscles is to flex
the wrist many people in the curl they
subconsciously Flex their wrist when
trying to get the weight up this can
lead to the forearms working harder than
they have to be and eventually lead to
fatigue and cramping instead next time
you do a curl first bend your wrist back
so that it's aligned with your forearm
and then keep it that way as you curl
when done properly you'll notice your
forearms are now far less involved and
your biceps are activating a lot more
than they used to next let's talk about
the elbows the primary function of the
biceps is to flex the elbow but whenever
you curl with a weight that's too heavy
for your biceps to lift your front delts
will start to help out by swinging your
elbow forward now some argue that this
elbow forward movement called shoulder
flexion is actually beneficial to do
when you curl because it's one of the
functions of the biceps this is true but
it's only a secondary function of the
biceps the front delts are far better at
performing this movement and in fact a
biomechanics expert coach casim tested
this and found that along with the
elbows to success will be sway forward
are in the curl led to less biceps
activation and more front Delta
activation the opposite of what you'd
want so instead keep your elbow locked
and focus on the primary function of the
biceps flexing the arm a little bit of
elbow movement is perfectly fine and
hard to avoid but anything more than
what's shown here will likely lead to
more of your front delts taken over
instead of your biceps so if you take a
look at my form now you'll notice I've
corrected all the mistakes I've
previously went through but there's
something else not visible to the eye
that could potentially slow your gains
to explain this let's refer to a 2018
paper that some bikiniers might remember
from some of my past videos within it
researchers had one group of subjects
perform the biceps curl while really
focusing on squeezing the biceps and
feeling the muscle work the other group
was instructed to Simply lift the weight
after eight weeks of this the group that
focused on feeling their biceps working
experienced almost double the biceps
gains now although proper form will help
you maximally activate your biceps
already some of you even with proper
form may have a hard time actually
feeling your biceps if that's the case
then try the soap with your arms by your
side flex your biceps as hard as you can
then bring your arm up in front of your
face and again Flex hard you should feel
a very strong biceps contraction when
your arm is in that position almost to
the point where your biceps are cramping
you don't want to do curls in that
position but you can do this to actually
feel what a strong biceps contraction is
like and then when you go into your
curls here's some additional tips first
rather than thinking about simply
lifting the weight up think about
pulling the bar or dumbbell into your
body and as you curl the weight out
focus on driving your pinkies up towards
the ceiling as if you are trying to
rotate your hands outwards this
emphasizes another function of the
biceps supination which can help you get
an even stronger contraction to get the
most out of every single rep if you want
to speed up your results then there's
some important that you're aware of all
the little details when it comes to your
exercise form not just for your biceps
but for all of your muscles for step by
