Ever since she's stopped being on active duty as a soldier of the Legions, Maara has taken up regular workouts which have resulted in her current rather bulked up build. To her, working out is a way to relieve stress and also a fun pasttime. Naturally this also provides the opporunity to show off which is another one of those things she likes so very much.

PS: I know it might not look that way but Maara is very much a woman. Charr as such lack any major sexual dimorphism and she's quite masculine on top of that.
