★★★★★ 5.0

"We love California Strong Athletics! Their expert coaches are kind and motivating. I can't believe how my daughter's skills have developed over the couple of years she has been here. I recommend it to everyone—especially if your kids actually want to learn gymnastics skills vs just doing obstacle courses."

"My son is absolutely OBSESSED with California Strong! He begs to go every day and can't wait for his next class. The coaches are truly invested in each child's development. It's clear they're not just teaching gymnastics, but building confident athletes. It's been a game-changer for my son's physical and emotional growth!"

Ivana S.
Parent, Recreational Program
★★★★★ 5.0

"Both of my kids are enrolled and they absolutely love it! The staff is incredibly accommodating—they helped us find overlapping class times so I could watch both kids without running between locations. The facility is clean, professional, and the coaches genuinely care about each child's progress. Worth every penny!"

Parent, Multiple Programs
★★★★★ 5.0

"The competitive team program here is top-notch. My daughter went from recreational gymnastics to competing at Level 5, and the coaching has been exceptional every step of the way. They push the athletes while keeping it fun and supportive. The team culture is unlike anything we've experienced—true community and genuine care."

Parent, Competitive Team
★★★★★ 5.0

"What sets Cal Strong apart is the intentional skill progression. My son isn't just doing random flips—he's learning proper technique from USAG-certified coaches who break down every movement. In six months he went from struggling with cartwheels to confidently performing back handsprings. These coaches know their stuff!"

The Foundation
WHY GYMNASTICS?

Ask any coach, trainer, or athlete what separates good athletes from great ones, and they'll tell you: it's the fundamentals. Body awareness. Balance. Strength. Flexibility. The ability to think quickly, adapt, and recover.

Gymnastics builds all of this faster and more completely than any other sport. It's not just about gymnastics—it's the foundation for every sport, and for life itself.

KinderGym students

Strength & Conditioning

Develops full-body strength, core stability, and functional power athletes need for every sport.

Body Awareness

Spatial awareness and body control that translates to faster learning in any athletic activity.

Mental Toughness

Builds resilience, focus, and the ability to overcome fear and push past limits.

Confidence & Character

Every mastered skill builds self-confidence and teaches discipline, perseverance, and goal-setting.

Have Questions?
FREQUENTLY ASKED QUESTIONS
What ages do you serve? +

We offer programs for ages 2.5 through 18+. KinderGym (2.5-5.5), Recreational Gymnastics (5.5-14), Tumbling (all ages), Competitive Teams (5-18), and Adult Gymnastics (16+).

How much does it cost? +

KinderGym starts at $125/month. Recreational Gymnastics (Levels 1-2) and Tumbling start at $145/month. Rec Level 3 starts at $170/month. We offer flexible month-to-month memberships with three tiers (Kickoff, Platinum, Ultimate). You can upgrade or downgrade anytime through your portal.

What is the 30-day trial? +

Yes! We offer a 30-day trial. Enroll, attend all your scheduled classes for 30 days, and if your child isn't absolutely loving it, we'll refund your tuition. The catch? You have to actually show up—one class isn't enough to know if gymnastics is right. Total risk: just the $75 annual insurance fee (non-refundable).

Are your coaches certified? +

Absolutely! All our coaches are USAG (USA Gymnastics) certified and trained in safety, progressions, and age-appropriate instruction. Many competed at collegiate and international levels.

What should my child wear? +

Comfortable athletic wear that allows full range of motion. Leotards, athletic shorts, and fitted t-shirts work great. No jeans or baggy clothing. Bare feet or gymnastics shoes only—no socks.

Can parents watch classes? +

Yes! We have a comfortable viewing area where parents can watch their children during class. We find that some younger kids focus better without parents in the gym initially, but you're always welcome to observe.

How do I cancel my membership? +

Log into your portal or email info@californiastrongathletics.com before the last day of the month to avoid being charged for the next month. Our memberships are flexible month-to-month with no long-term contracts.

Do you offer makeup classes? +

We don't offer traditional makeup classes. Instead, every membership includes 1-2 bonus classes per month depending on your tier. Use these as makeups when needed or for extra practice.

Can my kids take classes at the same time? +

We do our best to coordinate schedules for families! Email info@californiastrongathletics.com with your kids' ages/programs and we'll help find overlapping class times. Plus, you'll get a 20% sibling discount.

Can my child do both Rec and Tumbling? +

Yes! Since they're priced the same, you can use one Platinum membership ($185/month) for 1 Rec class + 1 Tumbling class per week. This is more cost-effective than two separate memberships.
