Can practice memorizing with a wide grip really make your back wider?

　　If you have been training in the gym for a while, then you may have heard this argument---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Three different grips were used to use the pull-down of the front neck pulley as a training action. During the experiment, electromyography was used to measure electromyography activation.

　The idea of ​​this experiment was that one of the grips would inevitably produce the greatest stimulation of the latissum muscle, and this would be the best grip to increase the size and strength of the back.

　These three grips are: distinguished by the spacing between the hands, which are shoulder width, one-half shoulder width and twice shoulder width, while the subject used 6RM weight as weight bearing.

　After the study, there was no obvious difference between these three grips. These three grips were comparable to those of the latissum muscle, and the only difference was the biceps brachii. The degree of participation of this phenomenon is reflected in the different training weights (6RM) that can be used when using different grips.

　　When the subject uses a double shoulder width grip, he cannot use the same weight training as the other two grips, although the stimulation of the back is not different from the other two grips.

　　I think almost everyone has this experience. The reason why the biceps are less involved in the wide grip is that they cannot directly pull the grip down. Because the distance between the palms is large, the distance between the elbows is also lengthened

　　So when the biceps are activated, the grip is not pulled too much, but the arms are retracted.

　　And from the above study we learned something, When you change the spacing between your palms, the stimulation of the back does not change significantly, at least when the straight grip (pals facing outward) and the elbows continue to face outward.

　　In other words, no matter whether the wide grip is narrow grip, there is no difference to stimulation of the latissimus dorsi! There is no saying that wide grip is wide! 　　The biggest change in changing muscle tension is: the direction of pulling down and the plane of the elbow joint.

　　In order to obtain different stimulation from the pulley pulley pulling down, you will need to pull the grip to the front, and keep the elbow direction outward during the pull-down process. In this way, the direction of tension will be horizontal and train to the upper part of the latissimus dorsi
