Ashe and Sejuani are from a Nordic inspired warrior race. Sejuani swings around her ball and chain like it's nothing, so of course she should have larger shoulders. Ashe on the other hand, while she can remain thin, for the most part, her arms should be crazy toned. She is pulling at maybe a 20-40 lbs string at upwards of 6 times a second. Like, I get that it's a magic bow, but still, that's crazy.
In the case of Ashe, No - Not really. Archery is an intensive sport, but not to the extent of creating extensive muscular growth. Let's have a look at Linda Ochoa, currently 8th in the compound Archery scene. http://www2.pictures.zimbio.com/gi/Linda+Ochoa+Archery+World+Cup+2015+Stage+1+W6qyLTKSNe6l.jpg For the most part, she is not exceptionally ripped, her arms are definitely strong though. As far as Arm anatomy goes, Ashe's arms are pretty up to par of what an IRL Archery professionals arms would be like. Her body weight is disproportionate, but her arms are fine.
Sejuani on the otherhand yes, she should more then likely see an increase in muscle tone. Let's have a look at Olympic Ball chain thrower, Betty Heidler https://aos.iacpublishinglabs.com/question/aq/1400px-788px/much-hammer-hammer-throw-weigh_3c0505ad738481b9.jpg?domain=cx.aos.ask.com This woman is built like a brick truck. It's important to take into mind, For this woman to throw the Ball Chain ONCE, she is required to be built like this. Your average Ball Chain weighs up to 35lbs, and Sejuani's flail would be a LOT heavier that that and she's swinging that thing over 6 times a minute. (Betty is NOTHING but muscle btw.) https://dz0obzljr6jvm.cloudfront.net/media/image/ef/e1/cd/betty_heidler_galerie_2.jpg
(Don't Olympic athlete's make the funniest faces???)
Some might call it out as Betty's genetics, but that's not the case. This body type is consistent amongst intensive sport players, from Shotput, to Ball Chain to Javelin, these body types are consistent.

It's also important to note, that unlike weightlifters, Olympics Athlete's bodies are made for function, not just for show.
TL;DR: Ashe's body is fine save for some body weight issues. Sejuani should be built a lot stockier however.
Ashe looks fine, you can see her muscles, they're just toned (Which is way more attractive than bulky muscles). You don't have to look ripped to have strong upperbody strength and she is probably in peak physical condition as well.
I like the idea of Sej being like a warrior, but I've always imagined Ashe to be like tribal nobility rather than a harsh, muscular warrior-queen
Sejuani being Illaoi levels of buff would definitely make sense, but Ashe feels more fitting being so tiny, as a squishy ADC, and especially one who focuses so much on scouting and kiting
I think Ashe is fine, maybe is not completely realistic but well, this is a fantasy game, some design are stretched on purpose.
I can give Ashe a pass mainly because I probably wouldn't notice a toned body for archery in this game unless I was actively looking for it.
Sejuani imo could be a bit bulkier, but I'll just have to be satisfied with her fan art for that.
I've seen threads like this before and I think Riot should really pay attention. I don't think either needs a drastic change, but some obvious beef and muscle tone should happen.
IMO Sej would look good in between what she is now and Illaoi. As big as Illaoi would be too much, but in between keeps her enough of the same but makes her more visibly strong in appearance.
I cannot pass any judgement with certainty on Ashe, but Sejuani a little beefing up.
20-40 lb draw-weight? What is she using, a kid's bow?
Come on now, that bow is almost as tall as she is. The closest parallel would be an English longbow, those things had draw weights of 80-110 lbs. They needed it to have a chance of piercing through some weak points in armor. They were so heavy that when archeologists looked at the corpses from the Mary Rose they could tell which ones were archers by the way the muscles developed causing permanent disfigurement in their skeletons.
If you wanted to make Ashe look realistic, she should look lopsided, with one bulging shoulder and a twisted spine. But, this is a fantasy game and I don't think Riot really wants to make one of their poster children look like that.
Sejuani could need a bit more musclemass,but then again its not like you can see her body in her classic skin anyway and she doesn't need to be Illaoi-levels of buff.
yes plz
muscle babes ftw
oooh i like me some strong ladies, i support OP's post. make 
and 
stronk
Ashe is an archer, it makes sense to not be a bigger, bulkier character because that's not the kind of athleticism her combat style requires or optimizes for.
Sejuani should be built like f@@@ing Illaoi though, flinging a giant ice mace around like a toy would make you bulk up like a power lifter.
Noty. Hot chicks only pls, this isn't Mass Effect Andromeda.
Ashe looks frail. Like a snowflake. I think she is supposed too. (as in, what they intended with her)
Ashe is totally fine as is. She's royalty and a "swift" (LOL, that movement speed) archer, not a bulky shield maiden on the frontlines.
I can understand your point about Sej, though. Then again, this is fantasy, and tits are nice.
I don't see any muscle maybe because his arms are covered but that hammer sure looks heavy. And he fcking jumps with it and swings it around and stuff...
Logic doesn't exist in league lol.
Eh, the archetype of archers is to look lithe and all. But Sejuani, on the other hand? I wish she looked more ripped.
vayne should have scoliosis or something from all that tumbling around.
If you're asking for more body diversity, then sure. If you're asking for a Fiora facelift...
Would you prefer Sejuani to have Illaoi's size? Just curious.
I think Ash is fine as she currently is as I think they designed her to seem a bit on the weak side for her will and determination to unite Freljord seem stronger, as for Sejuani I wouldn't mind if they gave her a bit more bulk, though maybe not Overwatch Zarya bulk I won't as I don't think it would suit her incredibly well I won't argue much if Riot decides to change her like that.
For Ashe, I'd say it makes a lot of sense for her to be relatively lithe. As an archer, her main skills should be arm-strength and precision, and you don't need to be super muscular to have good strength in your arms.
Sejuani on the other hand; She should probably be larger. Or at least a bit broader. Compared to what she used to look like, current sej is a massive improvement, but I wouldn't mind her being a bit larger. Not Illaoi size, but a smidge larger than she currently is.
I'd personally also like to know why the designers felt it necessary to leave cleavage in Sej's design when they changed her from "Bikini Cavalry" to "Badass Warlord". Like, I get it, people like tits, but to me at least that opening in Sej's outfit feels really... Out of place. She really doesn't feel like the kind of character to show cleavage to me.
Kinda related, but at least Irelia has an excuse lol
