Parent and Tot

Parent and child classes that encourage developing your child’s natural and physical ability in a fun and safe environment. Parents participation in class entices their children’s involvement in class. The more involved the parent the greater the experience for the child.

Ages: walking – 2 years old

The children learn coordination, fine and gross motor skills. We use specialized gymnastics equipment and props. Ball handling, body recognition and rhythm are other areas of our preschool program.

Ages: 3 – 4 years old

At NinjaZone, we are dedicated to creating early positive experiences with health, fitness, and sports. Baby Ninjas is the first step in creating confidence in young children! In an organized, yet playful structure, this parent and tot class is the perfect way to socialize your child, allow them to learn and understand what it means to follow instruction, and of course, get them moving!

Ages: walking – 2 years old


Lil’ Ninjas is the entry level to the all-new sport discipline inspired by gymnastics, martial arts, obstacle training, and freestyle movement.

Ages: 5-6 years old

NINJA Program

Children learn a combination of flips, rolls, jumps, and kicks. Strength and agility are tested through obstacle courses and various training techniques.​

A progressive level system evaluates and advances children in their skill and knowledge of core values as described in the NinjaZone creed. Children advance and learn at their own pace.​

The coaches are great. Firm but compassionate at the same time. They believe in what they are teaching. My daughter loves it! I would recommend J Star for any child at any skill level.

The coaches at J Star have been amazing! They were patient and encouraging with my daughter as she progressed from a shy (and often crying) preschooler to a confident little gymnast! Gymnastics is now her passion. Thank you J Star!
