Why Ninja Class?

1. Build Physical Strength »
Your kids will become stronger each week in a healthy environment utilizing our progressive training program.

2. Gain physical coordination »
Along with increased physical strength comes the fine-tuning of motor skills that contribute to one's overall coordination.

3. Develop Self-awareness »
You will see your child become more aware of what they are truly capable of accomplishing.

4. Gain self-confidence »
As they become stronger and faster, their self-confidence will grow, and they'll be able to take pride in the physical things they can now do and appreciate the progress they've made.

5. Increased mental focus »
Physical activity can also help their concentration skills, by providing a release valve for stress and pressure and encouraging higher levels of endorphins. If you can concentrate well on important work and social tasks, you’ll be happier overall.

6. Learn to overcome problems »
With each new obstacle comes new problems to solve.  Your child will learn how to problem-solve in a controlled and positive atmosphere.

7. Create strong friendships »
One of the biggest social benefits of exercise is just that – an improved social life. Especially if you participate in team sports or exercise with a group, you’ll develop greater empathy and social skills. You’ll also make new friends and gain new social outlets.

What Parents Are Saying About Our Gyms Around The Country!

This gym is such a breath of fresh air for a parent! The parking is easy, the seating in the observation room is nice, chairs can move around for strollers or wheelchairs, the kids are constantly moving for an hour on the obstacles/challenges, the coaches are encouraging and challenging, and they keep track of how each student is doing! My son recently achieved Level 1 for the course and they had a sweet minute at the end of the class to congratulate him. I think the training can be tailored for most kids. So helpful for kids who have loads of energy! My girls (9 and 11) and son (7) love it. My oldest was really nervous about her abilities/coordination, but was laughing and enjoying quickly at the start of her first class. We’re more excited to watch Ninja Warrior on TV now :)Also! We got to have a trial class which was really nice. The annual fee was around $60 per student, and monthly fee was about $150 per student (for weekly classes 1 hour each). Highly recommend this new business. I’m glad we get to have them in San Jose!

My son's 7th birthday party was a hit! All the kids and parents totally loved it. The kids couldn't stop talking about how much fun they had with Coach Arnaldo and his team. The coaches were awesome at keeping the kids entertained and involved. I totally recommend this place—it's great for kids to stay active, challenged, and it really gets them having a blast with all the cool obstacles.

We are very happy to have this facility in the South Bay. My child has been looking for a Ninja class for a couple of years and this facility opened up recently. It is run by Arnaldo and his family. They are warm and welcoming, and are highly motivated to teach the kids. I like how Arnaldo changes the course each class and constantly challenges the kids to get better. My child is having a lot of fun and looks forward to their class each week.
