Answer:
In general, and depending of course on the institution that issues the membership, exercise classes are not part of a basic membership holding, especially not for free.
Explanation:
Reading on internet, and especially researching different gym sites, free exercise classes are offered during a trial period, which is established for no longer than a month, mostly, but after that, almost all require a premium enrollment in order to offer access to all types of classes. But on a basic membership, these exercise classes are only reserved for free when there are special offers, or when there are trial periods to attract the client to engage in further spending.
