G3Kids

G3Kids is a gymnastics-based athletic program and interactive learning academy that offers gymnastics classes, ninja classes, parkour, Flip-2-Learn classes, enrichment and athletic classes, and evening athletic classes. The program also offers Open Gym, Work n Play where a parent remains onsite, gym rentals and parties, and camps. G3Kids is a children’s active learning center that teaches grit, grace, and growth in confidence while using a kinaesthetic learning method based on the idea that active bodies equal growing minds. The facility’s ninja course is described as one of the best equipped in San Diego and as San Diego’s best American Ninja Warrior Gym, and its foam pit has been replaced with an airbag that absorbs up to 90% of impact force from jumps and flips and is easy to disinfect and clean.

• Ages: 3–12 years old
• Price: If a family chooses to make a credit card payment, there is a 3% processing fee.

G3Kids states that it emphasizes maximizing brain stimulation through physical activity in an effort to reach a child’s highest potential for growth. The program notes that it will be exclusively accepting cash and electronic check (ACH) payments moving forward, with credit card payments still available but subject to the 3% processing fee. One parent, Kelly G., a San Diego mom, shared that her 4-year-old son took a class for about six weeks, that he loved it and looked forward to going each week, and that there was a talent show at the end to show tumbling skills. The same parent also described G3Kids as a great way to burn off kids’ excess energy and stated that she guarantees kids will love it.
