Classes
Our classes are designed to help kids move with purpose, and build confidence. With two separate gym spaces, we’re able to give every age group the attention they need. Our younger kids (under 4) have their own dedicated space to explore and grow, while kids 4 and up train in our main gym with age-appropriate challenges. It’s all about creating a positive experience where kids stay active, engaged, and excited to come back.

“All Out Ninja Sarnia has been a wonderful obstacle course race facility for my 7 year old boy and my 3 year old girl. The family that owns it and the coaching team are very friendly, accommodating and great with the kid.”
“My 3 year old grandson has been to the "open gym" 3 times in the past month. He loves it. He loves all the staff and knows 99% of them by name. The staff are very attentive and they play and teach the kids. The staff are good at encouraging and building the confidence of the kids. Good job ALL OUT NINJA staff.” -Deb
