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.
0.12we're going to make things a little bit1.56more technical now and move into basic4.71biomechanics and this means we're going6.87to analyze what muscles and what kind of10.08things are happening in your body when12.3you do the pull-up the primary muscle15.75groups for this type of exercise a18.47upper-body pulling exercise is going to21.84be what you call your lats your latinus25.65d'Orsay which if we were to turn around28.23are gonna be these big muscles along our31.17back and they essentially create our33.57wings of our back so it's gonna start up37.23from the elbow here and they run all the40.32way down across the side and towards the44.46bottom of your spine the second primary48.809muscle that is used is also your biceps52.44so your bicep is on the front here of54.69your arm and as the name suggests is bi58.109which means that there are actually two60.39muscles in here your short head earnings64.439called the short head of the bicep and66.18your long head of the bicep with this70.2particular pulling action the one that72.93you're going to be using is the long75.509head of the bicep so the long head and78the lat is what's going to create the81.47maximum amount of pulling when you do84.21the pull-ups84.99a good way of thinking about engaging87.619the lats and letting them lats do the90.9work is by thinking about when you're on94.079the bar instead of thinking about trying97.02to use your bicep and what a lot of99.6people do is think that they are pulling101.34here what you really want to do is think104.52about your elbow pulling down to your107.189side instead so you're doing this action110.31rather than here to here so instead of113.46this you're doing this okay and the idea117.42is that you can actually move your arm120.14quite far down without a bit having to124.439bend too much of the arm126.21okay so there's quite a lot of pull128.25happening with the lats now the reason131.7that we use the lats is big133.47they are the biggest muscle that we can135.72use to engage and do that pole the bicep139.74is also going to have to do work because141.96essentially to do this action of your144.99arm the bicep has to pull and contract147.75to bring your arm in so this is also151.5going to be used but the major part of153.84bringing your body up is going to be156.12this huge muscle down the back that is159.27going to do all of the pulling and then161.82it is going to be up to the bicep to do164.22the rest of it so these are the primary167.16muscles there are also what we'd like to170.37call antagonists so the antagonist173.28muscles are the ones that are going to176.22be working in the opposite way so when179.61we use our lats actually what was also182.88happening is our pecs185.13so our chest here is also going to be188.19using in the opposite way it's going to190.71be used in the opposite way and you're192.75going to feel that a lot more when you195.36are coming back down in the opposite197.79direction and the PEC is going to slow201.54your descent okay so the PEC is what we205.32call the antagonist and it is the207.27opposite the opposite muscle group to209.88the lats and the bicep so the third part213.06that I'd like to cover is what we call215.43the torque and tÃo are qu e so the220.29torque is tension essentially and the224.34way that you want to think about this is225.93in which direction is all of the tension229.86now an analogy that is pretty good to234.54make you remember this is if you were to237.45push out in a punch when you push out242.3you are going to internally rotate your246.48punch so when you see fighters you're249.18going to see that they're going to250.1internally rotate and the tension in252.87their shoulder it is internally rotated256.109okay256.859and they're going out when they pull258.6back what's happening is there's261.109external rotation so you're externally264.09rotating outwards as you come back266.9so internally rotated forwards when so269.3when you're doing a push-up you are271.04pushing in and externally when you pull274.76out now when that translates on to the277.43bar what that means is that when you are280.01pulling you want to think about282.52externally rotating out so your elbows285.47are gonna start coming in and you're287.51going to externally pull outwards so291.5imagine that you're bending the bar in293.15half outwards what you don't want to do296.27is pull and come in words and this is299.57the internal rotation when you're doing301.88the pull up you want to do external and304.61you're going to bring that elbow in and307.19using the lats and the bicep you're309.229gonna be pulling and externally rotating312.47obviously your hands are not going to be314.09able to do this they're not going to be315.74able to twist because the bar is solid318.05but you're going to feel that the319.699tension is outwards so we've looked at323.72the correct muscles being used the lats326.12and the bias there we've looked at the328.37antagonists the the pecs that are being330.68used for the opposite direction we've333.38got the talk down so in essence is336.32externally rotated in the shoulder so339.5you are going to find that you are341.51tensing outwards bringing those elbows344.63in as you pull and forth what we're348.889gonna have a look at is the stabilizer351.11muscles now these are going to be the353.75ones that are doing work in other places356.449and primarily for this we are looking at360.02the abdominals so the abdominals are362.96right here and what's going to happen is365.66they are gonna stabilize your body so368.84when you're doing the pull you don't371.69want your bottom half to be just moving374.3around what you need to be able to do is377.09put your body in the correct position so379.52we've already talked about the dish381.199shape position and you're gonna have to384.11contract your abs to do that okay it387.169also allows you control over your spine389.66especially your lower spine your391.55thoracic so rather than it moving in394.37weird positions and potentially causing396.71you harm you want to contract those ABS399.77make sure400.58everything is stable you have control403.37over your body and it is aligning your405.949hips so the stabilizer muscles are right409.189here the last point I'd like to cover is412.78breathing now it's something that's415.31often forgotten about when we are doing417.139exercise but the breathing part is very420.53important so when you're doing a pull424.159what you want to do is have a think427.31about holding your breath now when429.979you're doing the pull what's going to431.419happen is to support the ABS to434.12stabilize your spine holding your breath437.3is going to expand your lungs so you're439.55filling your lungs up with oxygen you're441.5holding it and that expansion in your444.86body is called inter abdominal pressure447.44and what's going to happen is it's going449.69to apply pressure internally which is452.629going to help stabilize your spine even454.759more you can see this most when you see458.81weight lifters squatting or dead lifting461.9you will see them holding their breath464.36when they are trying to exert energy and466.99what's going on is they're trying to469.52stabilize their spine and they're471.59creating that into abdominal pressure474.159pushing outwards to keep that spine476.69straight and reinforcing everything with479.69the apps' so as you're exerting your483.08energy to pull up you can hold your485.81breath when you get to the top you can487.789breathe out and then you come back down489.919again so we've now got four things five493.969things to think about extra when we are496.37doing our pull-ups we can start getting498.199a little bit more technical with how we500.479do the pull-up we've got to start502.55thinking about primary muscle groups so505.31we're not just doing all the work on the507.08biceps we're doing most of the work on509.479the lats the biceps are also going to be512.029used and primarily you're going to be514.849using the long head of your biceps so517.76the outside part of your bicep is the519.979one that is going to be used as well as522.079the lats on the way down the antagonist526.85muscle the PEC is going to be used as529.699you slowly come back down531.529thirdly the talk533.99externally rotated so you're going to be536.66really tensing outwards fourth you're540.02gonna be thinking about stabilizer541.7muscles your abs you're gonna make sure543.98that your hips are aligned you've got546.2control of your body everything is not548.63just loose and not doing and I think550.61you've really got to contract get those553.04abs involved554.18lastly breathing you're gonna hold your557.149breath as you pull up create that into559.91abdominal pressure breathe out at the562.279top as you come back down you can564.17breathe in again and you repeat the565.94process so here you can see that the big569.209green marked muscle groups is your lats572.6at the bottom this is how big that574.91muscle is and it stretches all the way577.43from the mid-back and the lower back all580.79the way around your side up to under the583.85shoulder and connecting and it all585.83connect all the way up to your elbow you588.11can also see that the bicep is590.12highlighted here and the bicep is gonna593.69be the long head of the bicep the outer596.42one and this is going to be also helping600.29around the front in blue you can see602.57here these are the abdominals and the605.779obliques server side muscles these are608.57going to be used for stabilizing when611.18you do the pull as well620.19you
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 tÃo 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
