FITNESS & SPA
Alameda Fitness & Spa is where performance meets community—a full-service health club that blends professional-level training with a family-friendly, high-energy atmosphere. As the proud continuation of Mariner Square Athletic Club, we carry forward a legacy of excellence while elevating the experience with world-class amenities and programs.
From high-energy CrossFit and elite strength training to state-of-the-art cardio and mind-body classes, we offer something for every goal and every level. Recover and recharge in our pool, spa, jacuzzi, and sauna, or train alongside the best with US National tennis programs, racquetball (leagues Monday & Thursday, casual hangouts Sundays) led by a world champion, premier BJJ instruction, and a dedicated karate school.
Whether you're here to push your limits, find balance, or simply enjoy the journey, Alameda Fitness & Spa is your home for health, strength, and community.

Share Alameda Fitness & Spa This Fall
This is our Fall 2-Day Guest Pass — a specially designed, Halloween-themed pass that gives friends and neighbors two full days to experience everything the club has to offer, from the weight room and studios to the pools and spa. We will have a counter set up at the club, and the passes will be dispersed throughout Alameda this season so they are easy to find and share.
Designed by our employee, Karina Krakowski.
