Little Brother's New Workout

I felt like I was going crazy. My little brother had always been a dork but recently he started going to the new gym that opened up in town. I don't know what the hell is going on there but something is up. 

He keeps talking about how great his trainer is and all the supplements, power drinks and smoothies he's on but I'm sure something is up with that place because he barely looks like a guy anymore, he looks like a girl, he's growing breasts, his butt his huge his hair is long and he seems...flirty. He doesn't seem to notice but I sure have, and he's getting hard to ignore, next time he goes to the Gym I'm going with him and getting to the bottom of this.
