O3 Strength FAQs

Do I need experience to join adult classes?

No. Adult classes welcome beginners through experienced members. Coaches help you choose appropriate movements, loads, and intensity.

No. Adult classes, Open Gym memberships, and private adult training are open to the wider community. You do not need to be part of a basketball or volleyball program.

Adult Unlimited includes coach-led classes plus 24-hour access. Open Gym is for independent workouts using the facility. Choose the coaching and flexibility that fit your routine.

Can I train privately or with a friend?

Yes. We offer individual and small group strength training for adults and youth, including groups of two or three. Sessions are available in 30- or 60-minute formats.

How does 24-hour access work?

Eligible members use the OpenPath app to enter the facility. Our team will explain setup, access rules, and court availability when you join.

Can athletes from other sports join?

Yes. We work across sports and with athletes starting at age 6 through high school, college, elite, and professional levels. Groups and plans are matched to age, readiness, experience, and sport. See Sports Performance for training options.
