Is it possible to cancel membership within 24 hours of creating it....?

I've been wanting to join a gym basically because the one I've been using at college is always filled with a bunch guys hogging the equipment. My college is currently under construction so theres only limited equipment in the athlete/commuter gym. So I'm pretty broke and after looking into planet fitness I thought I'd be getting my money's worth. I've spent the last two weeks looking into it. So I joined today and was planning on picking up my stuff tomorrow. BUT I just found that planet fitness doesn't have squat racks, benches, or allows jump ropes & deadlifts. I'm going to ask tomorrow, but I'm going to be pretty pissed if I just wasted money on a gym that has nothing. If I knew that I would have just invested in crossfit.

So do you think there is any way of taking back a membership if it hasn't even been 24 hours yet?
