Gyms with Group Classes in Costa Mesa, CA

9 of the 22 gyms we list in Costa Mesa have group classes.

Google's amenities list might flag a gym as having "group classes" without saying which ones run, how often, or whether non-members can even drop in — a gap that's invisible until you show up for a spin class that doesn't exist. Every gym on this page has its class schedule confirmed from the gym's own site or booking app, not a generic amenity checkbox.

Check the drop-in policy before you go. Many gyms sell a single class pass to non-members for around $15-25, but some require a membership or a free trial signup first — a quick look at the booking app saves a wasted trip.

Good to know

Can I take a gym class without a membership?

Many gyms sell single class passes or day passes to non-members, often through an online booking app like Mindbody or the gym's own site. Others reserve classes for members only, so it's worth checking the class schedule page before showing up.

How much do group fitness classes cost?

Drop-in classes typically run $15-30 depending on the type and city, while gym members often get classes included in their monthly dues or at a discounted punch-card rate. Specialty formats like cycling or reformer Pilates tend to sit at the higher end of that range.
