you'd think that, but I've gained 25lbs in the last 6 weeks or so as part of my fitness goal, and a lot of that has been focused on building my upper body in order to make my job a little easier (the stock I move is only about 42lbs/20~kg but I do it probably 150 times per sales floor shift). so whatever notions you may have previously had about my body type, they may be a little outdated. this is what I'm built like nowadays. my bird legs have turned slightly more froglike, which I think is awesome.
for reference, below is me in October, coincidentally in the same pair of jeans. this is actually more of a difference than I thought it'd be, there ain't a single bit of slack left in them anymore.
