I have been a member of the Strongsville Rec Center for at least the past 15 years. For a community center they do a nice job of keeping it clean and up to date.
The busiest days are Mondays but I still never have to wait for a machine regardless of the time of day. Bring your own music if you are going to do cardio, they play it but at the annoying level of not really knowing what song it is but just that something is on. If you are going to the weight room they do a nice job of playing loud music to cover up the grunting :)
They offer student discounts and its $10 a day if you aren't a member. Usually Mon-Wed are member only days after 3.
