Video Details

Understanding the biomechanics of exercises like pull-ups can greatly enhance your performance and protect against injury. When performing a pull-up, it’s essential to know which muscles are engaged and how to utilize them effectively. This tutorial will guide you through the primary muscle groups involved, how to achieve better technique, and additional tips to optimize your form.

When you initiate a pull-up, your primary muscle groups at work are the latissimus dorsi (the lats) and the biceps. The lats, located along your back, are the major players in pulling your body upward, while the long head of your bicep assists in this motion. To maximize efficiency, focus on pulling your elbows down towards your sides instead of just thinking of pulling with your arms. This engagement helps you emphasize your lats and take pressure off your biceps. Additionally, as you pull up, you should maintain tension by externally rotating outwards, which means your elbows should come in while pushing outward against the bar.

Incorporating stabilizer muscles and breath control is also crucial for a successful pull-up. Engaging your core and contracting your abs will help stabilize your spine, allowing for a controlled motion without risking injury. Remember to hold your breath while pulling up to create intra-abdominal pressure, which further supports your spine, and then exhale when you reach the top of the movement. Implementing these techniques will not only help optimize your pull-up but will also contribute to better overall strength and control during your workouts.

Highlights:

  • Engage your lats by focusing on pulling your elbows down rather than just pulling with your arms.
  • Maintain stability by contracting your core muscles and engaging your abs during the exercise.
  • Control your breathing by holding it during the pull and exhaling at the top for better spine support.

we're going to make things a little bit
1.56
more technical now and move into basic
4.71
biomechanics and this means we're going
6.87
to analyze what muscles and what kind of
10.08
things are happening in your body when
12.3
you do the pull-up the primary muscle
15.75
groups for this type of exercise a
18.47
upper-body pulling exercise is going to
21.84
be what you call your lats your latinus
25.65
d'Orsay which if we were to turn around
28.23
are gonna be these big muscles along our
31.17
back and they essentially create our
33.57
wings of our back so it's gonna start up
37.23
from the elbow here and they run all the
40.32
way down across the side and towards the
44.46
bottom of your spine the second primary
48.809
muscle that is used is also your biceps
52.44
so your bicep is on the front here of
54.69
your arm and as the name suggests is bi
58.109
which means that there are actually two
60.39
muscles in here your short head earnings
64.439
called the short head of the bicep and
66.18
your long head of the bicep with this
70.2
particular pulling action the one that
72.93
you're going to be using is the long
75.509
head of the bicep so the long head and
78
the lat is what's going to create the
81.47
maximum amount of pulling when you do
84.21
the pull-ups
84.99
a good way of thinking about engaging
87.619
the lats and letting them lats do the
90.9
work is by thinking about when you're on
94.079
the bar instead of thinking about trying
97.02
to use your bicep and what a lot of
99.6
people do is think that they are pulling
101.34
here what you really want to do is think
104.52
about your elbow pulling down to your
107.189
side instead so you're doing this action
110.31
rather than here to here so instead of
113.46
this you're doing this okay and the idea
117.42
is that you can actually move your arm
120.14
quite far down without a bit having to
124.439
bend too much of the arm
126.21
okay so there's quite a lot of pull
128.25
happening with the lats now the reason
131.7
that we use the lats is big
133.47
they are the biggest muscle that we can
135.72
use to engage and do that pole the bicep
139.74
is also going to have to do work because
141.96
essentially to do this action of your
144.99
arm the bicep has to pull and contract
147.75
to bring your arm in so this is also
151.5
going to be used but the major part of
153.84
bringing your body up is going to be
156.12
this huge muscle down the back that is
159.27
going to do all of the pulling and then
161.82
it is going to be up to the bicep to do
164.22
the rest of it so these are the primary
167.16
muscles there are also what we'd like to
170.37
call antagonists so the antagonist
173.28
muscles are the ones that are going to
176.22
be working in the opposite way so when
179.61
we use our lats actually what was also
182.88
happening is our pecs
185.13
so our chest here is also going to be
188.19
using in the opposite way it's going to
190.71
be used in the opposite way and you're
192.75
going to feel that a lot more when you
195.36
are coming back down in the opposite
197.79
direction and the PEC is going to slow
201.54
your descent okay so the PEC is what we
205.32
call the antagonist and it is the
207.27
opposite the opposite muscle group to
209.88
the lats and the bicep so the third part
213.06
that I'd like to cover is what we call
215.43
the torque and tío are qu e so the
220.29
torque is tension essentially and the
224.34
way that you want to think about this is
225.93
in which direction is all of the tension
229.86
now an analogy that is pretty good to
234.54
make you remember this is if you were to
237.45
push out in a punch when you push out
242.3
you are going to internally rotate your
246.48
punch so when you see fighters you're
249.18
going to see that they're going to
250.1
internally rotate and the tension in
252.87
their shoulder it is internally rotated
256.109
okay
256.859
and they're going out when they pull
258.6
back what's happening is there's
261.109
external rotation so you're externally
264.09
rotating outwards as you come back
266.9
so internally rotated forwards when so
269.3
when you're doing a push-up you are
271.04
pushing in and externally when you pull
274.76
out now when that translates on to the
277.43
bar what that means is that when you are
280.01
pulling you want to think about
282.52
externally rotating out so your elbows
285.47
are gonna start coming in and you're
287.51
going to externally pull outwards so
291.5
imagine that you're bending the bar in
293.15
half outwards what you don't want to do
296.27
is pull and come in words and this is
299.57
the internal rotation when you're doing
301.88
the pull up you want to do external and
304.61
you're going to bring that elbow in and
307.19
using the lats and the bicep you're
309.229
gonna be pulling and externally rotating
312.47
obviously your hands are not going to be
314.09
able to do this they're not going to be
315.74
able to twist because the bar is solid
318.05
but you're going to feel that the
319.699
tension is outwards so we've looked at
323.72
the correct muscles being used the lats
326.12
and the bias there we've looked at the
328.37
antagonists the the pecs that are being
330.68
used for the opposite direction we've
333.38
got the talk down so in essence is
336.32
externally rotated in the shoulder so
339.5
you are going to find that you are
341.51
tensing outwards bringing those elbows
344.63
in as you pull and forth what we're
348.889
gonna have a look at is the stabilizer
351.11
muscles now these are going to be the
353.75
ones that are doing work in other places
356.449
and primarily for this we are looking at
360.02
the abdominals so the abdominals are
362.96
right here and what's going to happen is
365.66
they are gonna stabilize your body so
368.84
when you're doing the pull you don't
371.69
want your bottom half to be just moving
374.3
around what you need to be able to do is
377.09
put your body in the correct position so
379.52
we've already talked about the dish
381.199
shape position and you're gonna have to
384.11
contract your abs to do that okay it
387.169
also allows you control over your spine
389.66
especially your lower spine your
391.55
thoracic so rather than it moving in
394.37
weird positions and potentially causing
396.71
you harm you want to contract those ABS
399.77
make sure
400.58
everything is stable you have control
403.37
over your body and it is aligning your
405.949
hips so the stabilizer muscles are right
409.189
here the last point I'd like to cover is
412.78
breathing now it's something that's
415.31
often forgotten about when we are doing
417.139
exercise but the breathing part is very
420.53
important so when you're doing a pull
424.159
what you want to do is have a think
427.31
about holding your breath now when
429.979
you're doing the pull what's going to
431.419
happen is to support the ABS to
434.12
stabilize your spine holding your breath
437.3
is going to expand your lungs so you're
439.55
filling your lungs up with oxygen you're
441.5
holding it and that expansion in your
444.86
body is called inter abdominal pressure
447.44
and what's going to happen is it's going
449.69
to apply pressure internally which is
452.629
going to help stabilize your spine even
454.759
more you can see this most when you see
458.81
weight lifters squatting or dead lifting
461.9
you will see them holding their breath
464.36
when they are trying to exert energy and
466.99
what's going on is they're trying to
469.52
stabilize their spine and they're
471.59
creating that into abdominal pressure
474.159
pushing outwards to keep that spine
476.69
straight and reinforcing everything with
479.69
the apps' so as you're exerting your
483.08
energy to pull up you can hold your
485.81
breath when you get to the top you can
487.789
breathe out and then you come back down
489.919
again so we've now got four things five
493.969
things to think about extra when we are
496.37
doing our pull-ups we can start getting
498.199
a little bit more technical with how we
500.479
do the pull-up we've got to start
502.55
thinking about primary muscle groups so
505.31
we're not just doing all the work on the
507.08
biceps we're doing most of the work on
509.479
the lats the biceps are also going to be
512.029
used and primarily you're going to be
514.849
using the long head of your biceps so
517.76
the outside part of your bicep is the
519.979
one that is going to be used as well as
522.079
the lats on the way down the antagonist
526.85
muscle the PEC is going to be used as
529.699
you slowly come back down
531.529
thirdly the talk
533.99
externally rotated so you're going to be
536.66
really tensing outwards fourth you're
540.02
gonna be thinking about stabilizer
541.7
muscles your abs you're gonna make sure
543.98
that your hips are aligned you've got
546.2
control of your body everything is not
548.63
just loose and not doing and I think
550.61
you've really got to contract get those
553.04
abs involved
554.18
lastly breathing you're gonna hold your
557.149
breath as you pull up create that into
559.91
abdominal pressure breathe out at the
562.279
top as you come back down you can
564.17
breathe in again and you repeat the
565.94
process so here you can see that the big
569.209
green marked muscle groups is your lats
572.6
at the bottom this is how big that
574.91
muscle is and it stretches all the way
577.43
from the mid-back and the lower back all
580.79
the way around your side up to under the
583.85
shoulder and connecting and it all
585.83
connect all the way up to your elbow you
588.11
can also see that the bicep is
590.12
highlighted here and the bicep is gonna
593.69
be the long head of the bicep the outer
596.42
one and this is going to be also helping
600.29
around the front in blue you can see
602.57
here these are the abdominals and the
605.779
obliques server side muscles these are
608.57
going to be used for stabilizing when
611.18
you do the pull as well
620.19
you

1
00:00:00,000 --> 00:00:04,000
we're going to make things a little bit

2
00:00:01,000 --> 00:00:06,000
more technical now and move into basic

3
00:00:04,000 --> 00:00:09,000
biomechanics and this means we're going

4
00:00:06,000 --> 00:00:11,000
to analyze what muscles and what kind of

5
00:00:10,000 --> 00:00:15,000
things are happening in your body when

6
00:00:12,000 --> 00:00:18,000
you do the pull-up the primary muscle

7
00:00:15,000 --> 00:00:21,000
groups for this type of exercise a

8
00:00:18,000 --> 00:00:25,000
upper-body pulling exercise is going to

9
00:00:21,000 --> 00:00:27,000
be what you call your lats your latinus

10
00:00:25,000 --> 00:00:30,000
d'Orsay which if we were to turn around

11
00:00:28,000 --> 00:00:33,000
are gonna be these big muscles along our

12
00:00:31,000 --> 00:00:37,000
back and they essentially create our

13
00:00:33,000 --> 00:00:39,000
wings of our back so it's gonna start up

14
00:00:37,000 --> 00:00:44,000
from the elbow here and they run all the

15
00:00:40,000 --> 00:00:48,000
way down across the side and towards the

16
00:00:44,000 --> 00:00:51,000
bottom of your spine the second primary

17
00:00:48,000 --> 00:00:53,000
muscle that is used is also your biceps

18
00:00:52,000 --> 00:00:57,000
so your bicep is on the front here of

19
00:00:54,000 --> 00:00:59,000
your arm and as the name suggests is bi

20
00:00:58,000 --> 00:01:04,000
which means that there are actually two

21
00:00:60,000 --> 00:01:05,000
muscles in here your short head earnings

22
00:00:64,000 --> 00:01:09,000
called the short head of the bicep and

23
00:00:66,000 --> 00:01:12,000
your long head of the bicep with this

24
00:00:70,000 --> 00:01:15,000
particular pulling action the one that

25
00:00:72,000 --> 00:01:17,000
you're going to be using is the long

26
00:00:75,000 --> 00:01:20,000
head of the bicep so the long head and

27
00:00:78,000 --> 00:01:24,000
the lat is what's going to create the

28
00:00:81,000 --> 00:01:24,000
maximum amount of pulling when you do

29
00:00:84,000 --> 00:01:27,000
the pull-ups

30
00:00:84,000 --> 00:01:29,000
a good way of thinking about engaging

31
00:00:87,000 --> 00:01:33,000
the lats and letting them lats do the

32
00:00:90,000 --> 00:01:36,000
work is by thinking about when you're on

33
00:00:94,000 --> 00:01:39,000
the bar instead of thinking about trying

34
00:00:97,000 --> 00:01:41,000
to use your bicep and what a lot of

35
00:00:99,000 --> 00:01:43,000
people do is think that they are pulling

36
00:00:101,000 --> 00:01:46,000
here what you really want to do is think

37
00:00:104,000 --> 00:01:49,000
about your elbow pulling down to your

38
00:00:107,000 --> 00:01:53,000
side instead so you're doing this action

39
00:00:110,000 --> 00:01:57,000
rather than here to here so instead of

40
00:00:113,000 --> 00:01:59,000
this you're doing this okay and the idea

41
00:00:117,000 --> 00:01:64,000
is that you can actually move your arm

42
00:00:120,000 --> 00:01:66,000
quite far down without a bit having to

43
00:00:124,000 --> 00:01:67,000
bend too much of the arm

44
00:00:126,000 --> 00:01:71,000
okay so there's quite a lot of pull

45
00:00:128,000 --> 00:01:73,000
happening with the lats now the reason

46
00:00:131,000 --> 00:01:75,000
that we use the lats is big

47
00:00:133,000 --> 00:01:79,000
they are the biggest muscle that we can

48
00:00:135,000 --> 00:01:81,000
use to engage and do that pole the bicep

49
00:00:139,000 --> 00:01:84,000
is also going to have to do work because

50
00:00:141,000 --> 00:01:86,000
essentially to do this action of your

51
00:00:144,000 --> 00:01:90,000
arm the bicep has to pull and contract

52
00:00:147,000 --> 00:01:93,000
to bring your arm in so this is also

53
00:00:151,000 --> 00:01:95,000
going to be used but the major part of

54
00:00:153,000 --> 00:01:98,000
bringing your body up is going to be

55
00:00:156,000 --> 00:01:101,000
this huge muscle down the back that is

56
00:00:159,000 --> 00:01:103,000
going to do all of the pulling and then

57
00:00:161,000 --> 00:01:106,000
it is going to be up to the bicep to do

58
00:00:164,000 --> 00:01:110,000
the rest of it so these are the primary

59
00:00:167,000 --> 00:01:113,000
muscles there are also what we'd like to

60
00:00:170,000 --> 00:01:115,000
call antagonists so the antagonist

61
00:00:173,000 --> 00:01:119,000
muscles are the ones that are going to

62
00:00:176,000 --> 00:01:122,000
be working in the opposite way so when

63
00:00:179,000 --> 00:01:124,000
we use our lats actually what was also

64
00:00:182,000 --> 00:01:127,000
happening is our pecs

65
00:00:185,000 --> 00:01:130,000
so our chest here is also going to be

66
00:00:188,000 --> 00:01:132,000
using in the opposite way it's going to

67
00:00:190,000 --> 00:01:134,000
be used in the opposite way and you're

68
00:00:192,000 --> 00:01:137,000
going to feel that a lot more when you

69
00:00:195,000 --> 00:01:141,000
are coming back down in the opposite

70
00:00:197,000 --> 00:01:144,000
direction and the PEC is going to slow

71
00:00:201,000 --> 00:01:146,000
your descent okay so the PEC is what we

72
00:00:205,000 --> 00:01:149,000
call the antagonist and it is the

73
00:00:207,000 --> 00:01:152,000
opposite the opposite muscle group to

74
00:00:209,000 --> 00:01:154,000
the lats and the bicep so the third part

75
00:00:213,000 --> 00:01:160,000
that I'd like to cover is what we call

76
00:00:215,000 --> 00:01:163,000
the torque and tío are qu e so the

77
00:00:220,000 --> 00:01:165,000
torque is tension essentially and the

78
00:00:224,000 --> 00:01:169,000
way that you want to think about this is

79
00:00:225,000 --> 00:01:173,000
in which direction is all of the tension

80
00:00:229,000 --> 00:01:176,000
now an analogy that is pretty good to

81
00:00:234,000 --> 00:01:181,000
make you remember this is if you were to

82
00:00:237,000 --> 00:01:186,000
push out in a punch when you push out

83
00:00:242,000 --> 00:01:188,000
you are going to internally rotate your

84
00:00:246,000 --> 00:01:189,000
punch so when you see fighters you're

85
00:00:249,000 --> 00:01:192,000
going to see that they're going to

86
00:00:250,000 --> 00:01:196,000
internally rotate and the tension in

87
00:00:252,000 --> 00:01:195,000
their shoulder it is internally rotated

88
00:00:256,000 --> 00:01:198,000
okay

89
00:00:256,000 --> 00:01:200,000
and they're going out when they pull

90
00:00:258,000 --> 00:01:203,000
back what's happening is there's

91
00:00:261,000 --> 00:01:206,000
external rotation so you're externally

92
00:00:264,000 --> 00:01:209,000
rotating outwards as you come back

93
00:00:266,000 --> 00:01:210,000
so internally rotated forwards when so

94
00:00:269,000 --> 00:01:214,000
when you're doing a push-up you are

95
00:00:271,000 --> 00:01:217,000
pushing in and externally when you pull

96
00:00:274,000 --> 00:01:219,000
out now when that translates on to the

97
00:00:277,000 --> 00:01:222,000
bar what that means is that when you are

98
00:00:280,000 --> 00:01:225,000
pulling you want to think about

99
00:00:282,000 --> 00:01:226,000
externally rotating out so your elbows

100
00:00:285,000 --> 00:01:231,000
are gonna start coming in and you're

101
00:00:287,000 --> 00:01:232,000
going to externally pull outwards so

102
00:00:291,000 --> 00:01:235,000
imagine that you're bending the bar in

103
00:00:293,000 --> 00:01:239,000
half outwards what you don't want to do

104
00:00:296,000 --> 00:01:241,000
is pull and come in words and this is

105
00:00:299,000 --> 00:01:244,000
the internal rotation when you're doing

106
00:00:301,000 --> 00:01:246,000
the pull up you want to do external and

107
00:00:304,000 --> 00:01:248,000
you're going to bring that elbow in and

108
00:00:307,000 --> 00:01:252,000
using the lats and the bicep you're

109
00:00:309,000 --> 00:01:253,000
gonna be pulling and externally rotating

110
00:00:312,000 --> 00:01:255,000
obviously your hands are not going to be

111
00:00:314,000 --> 00:01:257,000
able to do this they're not going to be

112
00:00:315,000 --> 00:01:258,000
able to twist because the bar is solid

113
00:00:318,000 --> 00:01:263,000
but you're going to feel that the

114
00:00:319,000 --> 00:01:265,000
tension is outwards so we've looked at

115
00:00:323,000 --> 00:01:267,000
the correct muscles being used the lats

116
00:00:326,000 --> 00:01:270,000
and the bias there we've looked at the

117
00:00:328,000 --> 00:01:273,000
antagonists the the pecs that are being

118
00:00:330,000 --> 00:01:275,000
used for the opposite direction we've

119
00:00:333,000 --> 00:01:279,000
got the talk down so in essence is

120
00:00:336,000 --> 00:01:281,000
externally rotated in the shoulder so

121
00:00:339,000 --> 00:01:284,000
you are going to find that you are

122
00:00:341,000 --> 00:01:288,000
tensing outwards bringing those elbows

123
00:00:344,000 --> 00:01:290,000
in as you pull and forth what we're

124
00:00:348,000 --> 00:01:292,000
gonna have a look at is the stabilizer

125
00:00:351,000 --> 00:01:296,000
muscles now these are going to be the

126
00:00:353,000 --> 00:01:299,000
ones that are doing work in other places

127
00:00:356,000 --> 00:01:302,000
and primarily for this we are looking at

128
00:00:360,000 --> 00:01:305,000
the abdominals so the abdominals are

129
00:00:362,000 --> 00:01:307,000
right here and what's going to happen is

130
00:00:365,000 --> 00:01:311,000
they are gonna stabilize your body so

131
00:00:368,000 --> 00:01:313,000
when you're doing the pull you don't

132
00:00:371,000 --> 00:01:316,000
want your bottom half to be just moving

133
00:00:374,000 --> 00:01:319,000
around what you need to be able to do is

134
00:00:377,000 --> 00:01:321,000
put your body in the correct position so

135
00:00:379,000 --> 00:01:323,000
we've already talked about the dish

136
00:00:381,000 --> 00:01:326,000
shape position and you're gonna have to

137
00:00:384,000 --> 00:01:329,000
contract your abs to do that okay it

138
00:00:387,000 --> 00:01:331,000
also allows you control over your spine

139
00:00:389,000 --> 00:01:333,000
especially your lower spine your

140
00:00:391,000 --> 00:01:336,000
thoracic so rather than it moving in

141
00:00:394,000 --> 00:01:339,000
weird positions and potentially causing

142
00:00:396,000 --> 00:01:339,000
you harm you want to contract those ABS

143
00:00:399,000 --> 00:01:342,000
make sure

144
00:00:400,000 --> 00:01:345,000
everything is stable you have control

145
00:00:403,000 --> 00:01:348,000
over your body and it is aligning your

146
00:00:405,000 --> 00:01:351,000
hips so the stabilizer muscles are right

147
00:00:409,000 --> 00:01:355,000
here the last point I'd like to cover is

148
00:00:412,000 --> 00:01:356,000
breathing now it's something that's

149
00:00:415,000 --> 00:01:360,000
often forgotten about when we are doing

150
00:00:417,000 --> 00:01:364,000
exercise but the breathing part is very

151
00:00:420,000 --> 00:01:366,000
important so when you're doing a pull

152
00:00:424,000 --> 00:01:369,000
what you want to do is have a think

153
00:00:427,000 --> 00:01:371,000
about holding your breath now when

154
00:00:429,000 --> 00:01:373,000
you're doing the pull what's going to

155
00:00:431,000 --> 00:01:376,000
happen is to support the ABS to

156
00:00:434,000 --> 00:01:379,000
stabilize your spine holding your breath

157
00:00:437,000 --> 00:01:381,000
is going to expand your lungs so you're

158
00:00:439,000 --> 00:01:384,000
filling your lungs up with oxygen you're

159
00:00:441,000 --> 00:01:386,000
holding it and that expansion in your

160
00:00:444,000 --> 00:01:388,000
body is called inter abdominal pressure

161
00:00:447,000 --> 00:01:392,000
and what's going to happen is it's going

162
00:00:449,000 --> 00:01:394,000
to apply pressure internally which is

163
00:00:452,000 --> 00:01:398,000
going to help stabilize your spine even

164
00:00:454,000 --> 00:01:401,000
more you can see this most when you see

165
00:00:458,000 --> 00:01:403,000
weight lifters squatting or dead lifting

166
00:00:461,000 --> 00:01:406,000
you will see them holding their breath

167
00:00:464,000 --> 00:01:409,000
when they are trying to exert energy and

168
00:00:466,000 --> 00:01:410,000
what's going on is they're trying to

169
00:00:469,000 --> 00:01:413,000
stabilize their spine and they're

170
00:00:471,000 --> 00:01:416,000
creating that into abdominal pressure

171
00:00:474,000 --> 00:01:419,000
pushing outwards to keep that spine

172
00:00:476,000 --> 00:01:422,000
straight and reinforcing everything with

173
00:00:479,000 --> 00:01:425,000
the apps' so as you're exerting your

174
00:00:483,000 --> 00:01:427,000
energy to pull up you can hold your

175
00:00:485,000 --> 00:01:429,000
breath when you get to the top you can

176
00:00:487,000 --> 00:01:433,000
breathe out and then you come back down

177
00:00:489,000 --> 00:01:435,000
again so we've now got four things five

178
00:00:493,000 --> 00:01:437,000
things to think about extra when we are

179
00:00:496,000 --> 00:01:440,000
doing our pull-ups we can start getting

180
00:00:498,000 --> 00:01:442,000
a little bit more technical with how we

181
00:00:500,000 --> 00:01:444,000
do the pull-up we've got to start

182
00:00:502,000 --> 00:01:446,000
thinking about primary muscle groups so

183
00:00:505,000 --> 00:01:449,000
we're not just doing all the work on the

184
00:00:507,000 --> 00:01:451,000
biceps we're doing most of the work on

185
00:00:509,000 --> 00:01:454,000
the lats the biceps are also going to be

186
00:00:512,000 --> 00:01:457,000
used and primarily you're going to be

187
00:00:514,000 --> 00:01:459,000
using the long head of your biceps so

188
00:00:517,000 --> 00:01:461,000
the outside part of your bicep is the

189
00:00:519,000 --> 00:01:465,000
one that is going to be used as well as

190
00:00:522,000 --> 00:01:469,000
the lats on the way down the antagonist

191
00:00:526,000 --> 00:01:470,000
muscle the PEC is going to be used as

192
00:00:529,000 --> 00:01:473,000
you slowly come back down

193
00:00:531,000 --> 00:01:476,000
thirdly the talk

194
00:00:533,000 --> 00:01:479,000
externally rotated so you're going to be

195
00:00:536,000 --> 00:01:481,000
really tensing outwards fourth you're

196
00:00:540,000 --> 00:01:483,000
gonna be thinking about stabilizer

197
00:00:541,000 --> 00:01:485,000
muscles your abs you're gonna make sure

198
00:00:543,000 --> 00:01:487,000
that your hips are aligned you've got

199
00:00:546,000 --> 00:01:490,000
control of your body everything is not

200
00:00:548,000 --> 00:01:492,000
just loose and not doing and I think

201
00:00:550,000 --> 00:01:493,000
you've really got to contract get those

202
00:00:553,000 --> 00:01:497,000
abs involved

203
00:00:554,000 --> 00:01:499,000
lastly breathing you're gonna hold your

204
00:00:557,000 --> 00:01:502,000
breath as you pull up create that into

205
00:00:559,000 --> 00:01:503,000
abdominal pressure breathe out at the

206
00:00:562,000 --> 00:01:505,000
top as you come back down you can

207
00:00:564,000 --> 00:01:509,000
breathe in again and you repeat the

208
00:00:565,000 --> 00:01:511,000
process so here you can see that the big

209
00:00:569,000 --> 00:01:514,000
green marked muscle groups is your lats

210
00:00:572,000 --> 00:01:516,000
at the bottom this is how big that

211
00:00:574,000 --> 00:01:519,000
muscle is and it stretches all the way

212
00:00:577,000 --> 00:01:523,000
from the mid-back and the lower back all

213
00:00:580,000 --> 00:01:525,000
the way around your side up to under the

214
00:00:583,000 --> 00:01:527,000
shoulder and connecting and it all

215
00:00:585,000 --> 00:01:529,000
connect all the way up to your elbow you

216
00:00:588,000 --> 00:01:533,000
can also see that the bicep is

217
00:00:590,000 --> 00:01:536,000
highlighted here and the bicep is gonna

218
00:00:593,000 --> 00:01:539,000
be the long head of the bicep the outer

219
00:00:596,000 --> 00:01:542,000
one and this is going to be also helping

220
00:00:600,000 --> 00:01:545,000
around the front in blue you can see

221
00:00:602,000 --> 00:01:548,000
here these are the abdominals and the

222
00:00:605,000 --> 00:01:550,000
obliques server side muscles these are

223
00:00:608,000 --> 00:01:553,000
going to be used for stabilizing when

224
00:00:611,000 --> 00:01:554,000
you do the pull as well

225
00:00:620,000 --> 00:01:562,000
you
