Kardia Ninjas

Fantastic experience: My kids went to Kardia Ninjas for summer camp 2025 and had a great time! My daughter loved it, and the staff were patient and kind with my autistic son. They played games, ran obstacle courses, and had outdoor fun. Joel, the owner, is great — very welcoming and great with the kids.

Fantastic experience: Just went for a kids birthday party! What a blast. Very friendly and inviting, kids had a great time, and the pricing seems fair. What a epic gem here in brantford.

Fantastic experience: Great people. Excellent venue. Highly recommended.

Fantastic experience: Joel and his staff are great, I recently visited the gym for a competition and it was really fun and well organized. Everyone was very friendly and helpful and you can tell they are passionate about the sport of Ninja. Go check it out, get a good workout and support a great local business

Fantastic experience: Expensive party

Fantastic experience: It is way harder than it looks. I suggest being able to do playground monkey bars and at least 5 pushups minimum so you can really have the most fun! Great spot for active kids.

Fantastic experience: Very nice set up gym for Ninja Warrior practice.

Fantastic experience: My kids love it here

Fantastic experience: I can't believe how amazing the coaches are (especially Joel) my daughter has just started taking courses, and the coaches really take the time with each kid. They are super encouraging, and if a kid is having a hard time grasping a concept the take the extra time to make sure they figure it out. It's been an absolute joy to watch as a parent!

Fantastic experience: Positive: Communication , Professionalism , Quality

Fantastic experience: Not only do my kids (5 & 7) love this place, but so do I. Seriously. Their staff are helpful and encouraging, which is so nice for a change. I'm not a super fit guy but that doesn't matter at this gym. They genuinely seem to care more about you enjoying what you're doing (and being safe) than about whether you're in shape or not. My kids keep asking to go back. I can't wait to take them. Heck, I can't wait to go back myself. Maybe for a guys night or a work trip. If you're tired of boring treadmills and muscle-bound jerks at those other gyms, you should check these guys out.

Fantastic experience: What a great new space in town!! Everyone had a blast and Joel and Austin were extremely welcoming and super helpful. Will definately be coming back
