MUSCULAR  ANATOMY 肌肉解剖——腿部
( e0 M9 a- u+ r) }4 c5 M, I& P  Yours legs are a massive collection of muscle groups, joints, and bones.
5 S3 ^$ U) _/ G& x. F- q$ i2 V) F* v, ]To better target specific muscles and increase the overall strength and
performance of your lower body, you need to know a little bit about your
anatomy and how each bone, joint, and muscle work together. Let's start with
7 V4 e2 v$ r( J4 O2 `! Pthe muscles.

  腿部由肌群、骨骼和关节组合在一起。为了针对性的训练目标肌肉和增加下肢总体强度和表现，在健身之前需要了解一点解剖学，每块骨、关节、和肌肉如何组合在一起。我们先从肌肉开始介绍。

2 h" j& G( A. P: P6 P; P" T6 g0 T; Z0 |

QUADRICEPS FEMORIS
  Your quads are made up of four main muscle groups—hence the prefix,
"quad." These muscles are the vastus lateralis, vastus medialis,
5 _( ~  y8 T# O7 y) M& m' `! z" q- Rvastus intermedius, and rectus femoris. These muscles work in concert to extend
your knee（伸膝关节）.

- j& n8 ^" W% y& J% P6 U0 T
VASTUS LATERALIS
A lot of bodybuilders and fitness athletes covet《渴求》 an outer-thigh sweep（广阔宽大）. This sweep comes from developing your
vastus lateralis, which sits on the outside portion of your thigh. The muscle
+ z8 `" p* y9 M2 @3 m' e6 r% kstarts at the top of your femur (thigh bone) and attaches to the patellar
tendon in your knee joint.
  e3 T; g$ T' T: B
  很多健身者和健美运动员都渴求宽阔的大腿外侧，宽阔的大腿来自于发达的股外侧肌，此肌肉位于大腿的外侧。起自股骨的上部，连接到膝关节的髌韧带。

  x6 R& N, R0 iVASTUS MEDIALIS
* A& P) a( w& x8 ]8 P% N( Y# nYou want that tear-drop shape on your inner thigh? Then you want a big
vastus medialis. The vastus medialis starts at the top of the femur and
attaches to the patellar tendon. The tear drop sits just above your knee on the

; M: c9 X! O8 C+ g

    你是否梦想大腿内侧锻炼的像汗珠样？这滴汗珠需要一块发达的股内侧肌。股内侧肌起始于股骨上部，也连接到髌韧带。汗珠正好位于膝关节上方大腿内侧。

VASTUS INTERMEDIUS

The vastus intermedius is deep in the middle of your thigh. You can't see
it because it's covered by the rectus femoris, but it also originates on the
) D) x: Y9 z0 `! {femur and attaches to the patellar tendon.
( c7 T/ W5 }7 k/ E( J- ?

HAMSTRINGS
If you want to develop big quads, you need to spend an equal amount of
/ f* F# q) I1 i* T6 V$ Utime developing the back of your legs. The hamstrings have three main muscle
& K. e  l* D8 r# V9 V! Jgroups: the biceps femoris, semimembranosus, and the semitendinosus. These
muscles work to flex your knee（屈膝关节）. In other words, they bring your heel toward your butt.

如果你想锻炼出发达的四头肌，也需要给予大腿后部肌群—腘绳肌以同等训练时间。腘绳肌主要由三大肌群组成：股二头肌、半膜肌、半腱肌。这些肌肉用来屈膝关节，亦就是说可以带动脚后跟踢向屁股。

BICEPS FEMORIS

The biceps femoris is a two-headed muscle. The long head runs from the
5 L5 c+ k3 r1 \! v) [3 s3 E+ Gischial tuberosity—or the sitting bones—and attaches to the fibula. The short
9 L' S. t$ C, }head originates on the back part of the femur and attaches to the fibula.

    股二头肌有两个头。长头起自坐骨结节，止点在小腿的胫骨。短头起自股骨后方，也止于胫骨。

This wide, flat, and deep muscle originates at the ischial tuberosity and

SEMITENDINOSUS
3 e6 F1 E3 u( _* O: V. n# QThe semitendinosus runs from the ischial tuberosity and also attaches to
the tibia. This muscle is notable for the length of its tendon insertion, which

& Y# n5 ]' M; {& j半腱肌起自坐骨结节，也止于腓骨。此肌的特点是它很长的韧带，可以部分的切除来替代磨损的前十字韧带（位于膝关节内的韧带）。

GLUTES

We like to talk about glutes because of their potential beauty, but it's
important to note that the glute muscles are hugely important for keeping our
# |  }6 |8 U3 ]% A6 ctrunk upright. We don't have big butts just for looks, after all. The gluteal
muscles are made up of the gluteus maximus, the gluteus medius, and the gluteus
minimus.

, m; P* |% y, g7 r1 [& c: J

    我们喜爱谈论臀肌，是因为它潜在的美，但臀肌的重要性在于保持躯干挺直。最终我们不能拥有这样一个丰满的臀部。臀肌主要由臀大肌、臀中肌和臀小肌组成。
/ N- i' h) C: K& ~. B; Z
GLUTEUS MAXIMUS
) C0 o9 [8 F1 H- NThe glute maximus is the most visible muscle and is what people spend the
most time developing. The glute max starts on your sacrum (the triangular bone
at the base of the spine 骶骨) and your lumbar fascia (腰筋膜connective tissue in your lower back) and attaches to your iliotibial
  T8 }8 M) M$ R( gtract（髂胫束）, or your IT band. It also attaches to your outer thigh.
$ c* K) R4 k4 `  B
   臀大肌是最易看到，很多人花大把时间来锻炼的一块臀肌。臀大肌起自骶骨和腰筋膜，止点在大腿外侧下方的髂胫束。

GLUTEUS MEDIUS

People aren't usually too concerned with the glute medius because it's
1 g" `  D' G0 Q( w% sdeeper and you can't see it, but the glute medius is an important muscle. It's
a critical stabilizer（固定者） of the hip and thigh. It runs from the top of your hip bone (the iliac
( G9 k3 l" a/ u* w$ ?crest：髂脊) and attaches
7 O) b& R' \. L. }to your outer thigh.

锻炼者对臀中肌关注不多，因其位置较深，不能看到，但看不到不等于不重要。臀中肌是髋骨和大腿的固定肌肉。起自髋骨的髂嵴，止点在大腿的外侧。

GLUTEUS MINIMUS
Even deeper than the glute medius is your glute minimus. It's a very small
muscle that starts on the outer portion of your hip and attaches to the outer
thigh.
+ p5 s9 D9 p  h$ Z: \- m
比臀中肌更深的是臀小肌，体积很小。起自髋骨外侧，止点在大腿外侧。

ADDUCTORS
We've all sat in the adductor-abductor machine and wondered, "Why am
3 K  O1 r9 @/ j- C7 w3 |4 E, DI doing this?" The adductors are actually very important muscles. There
are five muscle groups to discuss here, and all of them originate at the inside
! f% C' h) ^7 t7 k1 I% @/ nof your hip (pubis：耻骨) and attach to the inside of your thigh. The adductors are layered（分层存在）, almost like the shape of a fan.

" h  D" v' Q% h当我们坐在内收外展训练机上感到奇怪，为何要做这个动作？内收肌实际上很重要，由五块肌肉组成，均起源于髋骨中的耻骨，止点在大腿内侧。内收肌分层排列，犹如扇形。
1 _" W$ \6 O" A# I) g$ u

In terms of training, the adductors are important for stabilization. They
don't get much use in common movements, so it's important to work them
specifically. Strong adductors help you stabilize during unilateral movements（单侧运动） and are essential to a good squat.

6 a( F% J# M+ F' L$ w9 i4 i% t从锻炼的角度来说，内收肌群对于下肢的稳定至关重要。内收肌在一些常规动作中用不到，在特殊动作中用到。强壮的内收肌有助于单侧运动时的稳定，是完美下蹲的基础。

) r( V. T! U. a2 E( hPECTINEUS
The pectineus begins on the pubis and attaches to top of femur.

耻骨肌起自耻骨，止点在股骨上部。

ADDUCTOR BREVIS

  R7 T" H% D, V7 I5 d4 m1 E2 NThis muscle lies next to the pectineus and attaches lower on the femur.

短内收肌与耻骨肌相邻，止点在股骨下端。

* |2 k0 ~" o- r2 ?ADDUCTOR LONGUS

The adductor longus runs from the pubis and attaches below the brevis.

长内收肌起自耻骨，止点在短内收肌的下方。

ADDUCTOR MAGNUS
/ m$ {/ t2 G/ V/ W4 ^4 E$ H5 tThis is probably the biggest adductor. It runs from your pubis and has
attachment points at the top of your thigh and down a little lower on the
inside of your mid thigh.

大内收肌是内收肌中最大的一块。起自于耻骨，止点在大腿上端的收肌结节，先下到大腿中部内侧。
3 S) I& g3 m8 J- N
GRACILIS

The gracilis is a long adductor. It originates on your pubis and attaches

8 I& i+ S8 j/ W) k7 q. I! }% n5 NThe cool thing about front squats is that you hit almost every muscle in
your legs. As you sit down into the squat, you lengthen the quads and load the

   前深蹲的迷人之处是可以刺激大腿的每一块肌肉。当深蹲时，拉伸股四头肌，施加荷载给腘绳肌和臀肌。当起身时，伸膝关节并刺激股四头肌。如果你想用一个动作来锻炼大腿，我推荐这个。这是一个给你巨大回报的锻炼方法。

EXERCISE 3 LUNGES（马步前进）

Training on one leg changes the stress on your muscles and forces your

% P/ r$ f- m/ v: gminimus and adductors to stabilize your knee and control the movement.

9 L6 W, p+ w) r% [4 t3 c我们介绍马步压腿，是因为此动作可以刺激腿部的各块肌肉。当你跨出步子和收回步子的时候时，股四头肌可以伸膝关节。而臀肌和腘绳肌可以使你下压，也可以助你起身。除了用到这些大块肌肉，还要用到臀小肌和固定膝关节并控制运动的内收肌群。

EXERCISE 4 STANDING CALF RAISE 站姿提踵

You can use your bodyweight, dumbbells, or a barbell with this movement.
5 G9 G: d. v  N7 Q2 iThe best thing about calf raises is that they're hard to mess up. Keep your

bottom of the movement, give the stretch a second or two before coming up to a
big squeeze at the top.
