losing muscle Options

[lKVNiiKINKYl]

Is it possible? I need to lose weight for Crew and I want to know what is a good way to do it. Just to let you know, I do work out everyday (except sunday) after school doing running or something cardiovascular for long periods of time. Typically for practice, I run for around 30 minutes and we always do a ten minute warm-up run. If we do any less than 30, it's usually timed so I would like to say I get a decent amount of cardio in considering I do it everyday. I am 5'4 and I weight about 125 pounds and I've been at this weight a while. I was the same weight even since I began practice and for some reason I won't go down. Is there anyway way I can lose muscle (I'm not that "diesel", but there I would say I still have a somewhat decent amount) because it has been about two and a half months of me eating good foods and working out and my weight just stays the same.
