Look at whether the floor is kept clean and the machines are maintained, whether staff are around to show you how to use things, and whether the classes or sessions you want run at times that suit you. Many members find that a trial visit tells them more than any brochure, so try the place at the hour you would really train. Long-term members often say the atmosphere matters more than the kit. Check the cancellation and contract terms before you sign anything.
