Walking into a small gym like 24 Hour Fitness?

Would it be weird of me to go up there and ask if there's any type of job I could get there? Such as racking weights and just such and such. I'm 18, workout regularly, knowledgeable to exercises and what works what and machines and body awareness. I'm in college studying kinesiology/physical therapy. I've taken classes such as medical terminology, health, biology and so on. What do you think kind of reply I would get?
