this has already been somewhat covered, but i just wanted to emphasize this point - everything, everything, is an opportunity for a 'character piece.' or, a chance to flesh out your character.
this is particularly true as most roleplays tend to be 1x1s, where characterization is arguably more important than anything else. pardon my french but - what makes your character more fuckable than everyone else in that multiverse? the answer to that question goes far deeper than 'he stronk' or 'she hot'. both of those traits are dime a dozen in roleplay. what really makes the reader connects with the main cast though? it's characters that come off the sheets. characters with multi-faceted personalities, backstories that have meat and funny stories. depth, nuances, progression. the golden standard in a long-term rp is that whenever something happens (a new foe arises, an argument occurs, etc.), the reader should be able to point at your character and say, 'i think this character will behave in roughly this fashion.' would they know exactly what action or exactly what dialogue said character will do or say? no, but they should get the gist. at that point, i would say, amazing, you've successfully conveyed what you needed to convey of who she or he is
^take that last bit with a grain of salt though. if a character's response to everything is 'murderhobo it', that is predictable, but uninteresting.
besides, i've never seen anyone complain if you write an extra 200 words or so just describing how attractive your character is performing a certain action.
His battle-honed physique tightened, arms flexing like bows drawn taut. He brought the greataxe down - thunk - splitting wood with a tool unfitted for its purpose, with the unspent violence knitting his brows and clenching his teeth from a foe that yet evaded him. A waste of the sharpness of his weapon, but necessary. Stranded as they were, firewood was essential, and he would provide warmth for his unexpected allies as a show of good faith. Sweat glistened his naked back, rivulets highlighting tendons and emphasizing the inverse v of his build, licking along the deep shadow of that muscle-flanked line splitting down the middle. Even in the dead of winter, he needed no protection from the elements. No, the Iceborne was a furnace all by his lonesome, fueled by that ceaseless inner fire that bellowed with every heave. Again! The greataxe raises high, deltoids clenched and biceps bulged, every atom working in unison - thwaak! He would return to his village triumphant! This monstrosity that lurked just beyond the hungering edges of his axe shall become the new pelt wreathed around his loins, reduced to another harrowing story to tell around campfires. Like this lifeless log he split, so too, shall his foe lay wasted and fallen beneath the unconstrained power of his rage and conviction.
tl;dr: buff dude split some firewood while angry, but hotter and with more character development. easy filler! :v
