Recess Was the Best Part of the Day
Momentum opened in 2020 in Northeast Minneapolis on a simple, joyful idea: that the best workout doesn't feel like a workout at all — it feels like recess. Six years later, our 40-plus obstacles have turned thousands of Minneapolis kids, teens, and adults into stronger, braver, grinning versions of themselves, one warped wall and flying leap at a time.
Here's the magic of ninja training: chasing an obstacle is so much fun that you forget you're building serious strength, agility, balance, and grit — and that's exactly why it works, especially for kids who'd never touch a treadmill. Behind the fun is real substance. Our coaches are certified in movement and obsessed with safety: everything is padded, supervised, and scaled, so a nervous five-year-old and a competitive teen both get challenged at exactly their level, and everybody lands soft. We build confidence as deliberately as we build strength, because watching a shy kid conquer an obstacle they were scared of — and light up — is the whole reason we do this. Kids' classes, teen and adult ninja, open gym, camps, parties, and a competition team that's traveled the Midwest: whatever brings you in, you'll leave stronger and smiling. Your first class is free. Come play.

The Best Screen-Time Antidote There Is
Three reasons families across Minneapolis make Momentum part of their week.
They're Moving, Not Scrolling
Ninja is so much fun that kids beg to come — no bribing required. It's the rare activity that pulls them off the couch and leaves them genuinely, happily exhausted.
They're Building More Than Muscle
Strength and agility come free with the fun, but so do focus, resilience, and courage. Kids learn to fail at an obstacle, try again, and finally conquer it — the most important skill there is.
They're Making Real Friends
The ninja community is warm and supportive, cheering each other up the wall. Kids build friendships and belonging here that reach far beyond the gym.
Minneapolis Loves Momentum
My eight-year-old was shy, unathletic, and glued to a screen. Six months at Momentum and he's a different kid — he's climbing the warped wall, he's made real friends, and for the first time he's genuinely proud of what his body can do. The coaches are incredible with kids: patient, encouraging, and safety-obsessed. He counts down the days between classes. Honestly, it's done more for his confidence than anything else we've tried.
I signed up for the adult ninja class as a joke and it's become the highlight of my week. It's the most fun I've ever had working out — one hour flies by, I'm shockingly sore the next day, and I'm building strength I never got from a regular gym. The obstacles scale to any level, the coaches cheer you on, and there's zero ego. I never thought 'recess for grown-ups' would get me in the best shape of my life.
We've thrown two birthday parties here and they were both absolute magic. The kids had the time of their lives on the obstacles and in the foam pit, the coaches ran the whole thing so we could actually relax, and every parent asked where we found the place. Stress-free for us, unforgettable for the kids. Momentum has completely ruined every other birthday venue for our family.
My daughter joined the competition team two years ago and it's shaped who she is. She's strong, focused, and resilient, she's competed across the Midwest, and she carries the confidence from this gym into everything. But what I love most is the culture — the coaches build character as much as skill, and the whole ninja community lifts each other up. Momentum isn't just a gym; it's the best thing that's happened to our family.
40+ Obstacles. Endless Grins.
Warped walls, swinging rings, cargo nets, and the softest foam pit in the Twin Cities — come see where Minneapolis comes to play.
First-Timers Are Our Favorites
Whether it's a nervous five-year-old, a teen who thinks they're 'not athletic,' or a grown-up who hasn't played since childhood — the total first-timer is exactly who Momentum is built for, and genuinely our favorite ninja to coach. You do not need to be strong, coordinated, or brave to start; those are the gifts ninja gives you.
Every obstacle scales, so there's a version for every body and every level, and our coaches are experts at meeting a newcomer exactly where they are — starting easy, building confidence, and turning 'I can't' into 'I did it!' faster than you'd believe. Everything is padded and supervised, so parents can relax and first-timers can be brave. Your first class is completely free, with zero pressure and zero commitment. Worst case, you (or your kid) have an absolute blast for an hour and get a great workout. Best case, you find the activity that becomes the highlight of the week, builds strength and confidence that last, and a community that cheers you up every wall. Come exactly as you are — we'll bring the high-fives.

Ninja Gym FAQs
What ages do you take?
Everyone five and up! We have dedicated Kids Ninja classes (ages 5–12) grouped by age and level, Teen & Adult Ninja classes, open gym for all ages, birthday parties, camps, and a competition team. Whether it's a five-year-old's first warped-wall attempt or a grown-up rediscovering recess, there's a class built for you. Little ones under five aren't quite ready for our obstacles, but they'll be counting the days.
Is it safe? My kid (or I) can be clumsy.
Safety is the foundation of everything we do. Every obstacle is padded, the foam pit is deep and soft, and every class is fully supervised by coaches trained in movement and spotting. We scale each obstacle to the person, so nobody is ever pushed past what's safe for them, and 'clumsy' is exactly who we love to build up. Falls are soft and part of the fun — that's the whole point of all the padding.
How does the free class work?
New ninjas get their first class completely free, with no commitment. Pick a class that fits — Kids Ninja, Teen & Adult, or open gym — and come try it. A coach will match you to the right level and guide you through your first obstacles. It's the best way to feel the fun and see the coaching for yourself. There's no obligation to sign up. Just fill out the form on this page and we'll get you booked in.
Do you host birthday parties?
We do, and they're legendary! Our party packages include private or semi-private access to the obstacles and foam pit, a dedicated coach to run the whole thing, and a stress-free setup so parents can actually relax. The kids get an unforgettable, active celebration, and you get zero cleanup. Parties book up fast, especially on weekends — reach out early and we'll help you plan the best birthday your kid's ever had.
Is ninja actually a good workout?
Absolutely — it's one of the most complete workouts there is, disguised as pure fun. Running obstacles builds functional strength, grip, agility, balance, coordination, and cardio all at once, using your whole body. Adults are consistently shocked at how sore they are the next day, and kids get a full-body workout without ever realizing it. It's why ninja works so well for people — especially kids — who find regular exercise boring.
What should we wear and bring?
Just comfortable athletic clothes you can move and climb in, and athletic shoes with good grip — no sandals or slippery soles. Bring a water bottle. We provide all the obstacles, mats, and equipment, and grippy socks aren't required (proper sneakers are best). Arrive about ten minutes early for your first class so a coach can get you signed in and set up. No experience and no special gear needed — just show up ready to play.
