"Slender," may not be the word. I don't know what the word would be. (Not a "twink"-ish build.) It'd probably be more of a muscular build but not a really big bodybuilder type. Based on my build, I've been asked before if I had been a wrestler. Smaller stature; broadish-shoulders, built torso; thinnish waist in comparison to shoulders, with a "bubble butt"- ha; I run; fit. (Though, lately, I've not been regularly exercising at all. Got to get back to it!) As you can tell, I don't describe my build so much, ha.
