It is more economical to have a monthly membership rather than a 10 block pass if you attend classes more than once/week. The 10 block pass costs you $13/class and at $65/month once you attend 6 classes in a month then the membership is more economical. If you plan on attending more frequently for a few months then the tri class pass may be best for you. Passes bought through Fit4Mom San Diego are good at any of our locations within our San Diego franchise. If unsure which pass is best for you, consult with any of our instructors and they can help you decide. You can buy the passes online or from any of our instructors at class.
