Building Wings: Is it really about proper grip width or are effort and genetics the real determinants of your wing-size?

Even though it's more difficult (you can handle less weight), the wide grip is not necessarily more effective. Individuality counts & difficult does not equal effective: In view of interpersonal differences and the fact that it is, much contrary to popular believe, not the exercise or way to execute a certain exercise that hurts the most, which is most effective, it is well possible that the previously mentioned "generations of bodybuilders" were right and the extra-wide grip gave them their impressive wingspan. It is yet equally possible that they fooled themselves into believing that this was the most effective way to perform the exercise due to the "good pain" they (mis?)interpreted as a signal of optimal muscle stimulation.

sets were not performed until or close to failure

In the study referenced in the SuppVersity EMG Series, it's the underhand shoulder- wide grip which produces a maximal activation of the latissumus dorsi - the wings, so to say | learn more "To simulate a set in a typical workout, the participants performed a 6RM test (Pollock. 1998, Bird. 2005, Kraemer. 2004), which corresponds to approximately 85% of 1RM (Baechle. 2008) and is a recommended intensity for increasing muscle strength and hypertrophy (American College of Sports Medicine. 2009, Peterson. 2004).



By using equal relative load for each exercise with heavy loads performed to volitional failure, we can assess the practical significance of how the independent variable, grip width, affects the dependent variable, muscle activation." (Andersen. 2014)

Values are given as mean 6SD (Andersen. 2014)

Figure 3: If total time under tension (TUT | learn more) determined your gains, a medium grip would excel. When all is said and done, we are thus - once again left with the ultimately valuable insight that it's not really worth to overthink the matter of "optimal muscle stimulation". The time you waste pondering the pros and cons of certain grip widths, of which you don't even know if their effects on the electromygraphical activation does even relate to their mass- and/or strength-building qualities, would be better spend actually doing lat pulls, or - even better - pull ups.

As areader you will be well aware that the term "optimal" in conjunction with grip width will always be goal-specific. It is, for example, well possible that you would have to use completely different grips to "optimally" train the posterior chain of the rotator cuff muscle and your lats and the results Vidar Andersen and his colleagues from the, theand theat thepresent in their latest paper in thecould help us to find out which grip widths these are (Andersen. 2014).While the researchers point out, "the effects of pronated grip widths in the anterior lat pull down are not yet fully determined" (Andersen. 2014),readers know better. There is actually conclusive evidence from a study by Boeckh-Behrens & Buskies I discussed at length in thethat an optimal stimulation of the latissumus dorsi is achieved with a shoulder-wide and thus probably 10-15 cm narrower overhand grip; and not with the popular "grip-as-far-apart-as-possible crucification" grip generations of bodybuilders considered the "optimal wing builder."I am not sure, whether or not Andersen et al. even know the said study, the results of which have only been published in German. What they do know, though, are the results of a similar, yet small-scale study by Lusk et al. with methodological issues- e.g.:As the Swedish researchers rightly point out, the two latter "methodological limitations make it difficult to transfer the findings to real life training" (Andersen. 2014). To underline the validity of this claim, the scientists cite a set of studies by Saeterbakken et al. (2011-2013) to substantiate the hypothesis that using equalloads when comparing different exercises is a prerequisite for a reliable comparison of different exercises and exercise modalities.Accordingly, a within-participant repeated-measures design was used to examine the6RM strength and concomitant EMG activity in anterior lat pull-down using narrow, medium, and widepronated grip widths, defined as 1, 1.5, and 2 times the biacromial distance (BAD), respectively (see).As Andersen et al. point out, "the participants took part in 1 session approximately 1 week before the experimental test to familiarize the participants with the procedures and identify the 6RM load for the different grip widths." For the test, the exercise order was randomized and counterbalanced for each participant and was identical in the habituation and experimental tests.Thus, the scientists hope to produce practically relevant results, which would make an "important" contribution to the "knowledge for athletes and coaches" (Andersen. 2014) -- and in view of the fact that their subjects were 16 healthy (age, 24 years; body mass, 81 kg; stature, 180 cm) with 63 years of resistance training experience the latter, i.e. practical relevance, may actually have been achieved.Whether or not the same can be said of the differences you see inis yet (imho) questionable; and that not simply because of the negligible effect size, but also due to the fact that we still don't know how and if high EMG values of which we believe that they tell us something about the intensity of the muscular contraction are even associated with skeletal muscle growth and / or strength gains.In their discussion of the results, Andersen et al. sidestep this issue and zone in on the quasi non-existent differences between narrow, medium, and wide pronated grips in the anterior lat pull-down, pointing out that a medium grip may still "have someminor advantages over small and wide grips", because - and this is a non-sensical assessment imho - "the biceps brachii had greater activity using a medium compared with a narrow grip in the concentric phase" (Andersen. 2014)And while Andersen et al. are right and the overall activation of the latissimus dorsi does not appear to be significantly impaired by the increasing biceps involvement, it's still not exactly, what the previously referenced real trainer or trainee will be interested in.
