The WBA, WBC, IBF, WBO, and BoxRec have standard weight classes that they assign to boxers. My walkaround weight of 138 pounds places me in the Super Lightweight/Junior Welterweight division. This class has traditionally been highly-skilled, ferocious fighters—individuals who I will likely spar with as I mature in boxing.
With sufficient training, I will increase my muscle mass and decrease my fat, so my competitive weight would likely hover around 134 or 135 pounds. I don’t expect to lose much weight because I am naturally svelte, much like Sammy Davis, Jr. (but I am, admittedly, a tad taller, heavier, and much more handsome than Sammy). With the weight adjustment, my competitive weight class would, most likely, be Lightweight.
