About this gym
Maine Warrior Gym is South Portland's premier ninja warrior and parkour training facility for kids and families, located at 333 Clarks Pond Pkwy behind the Maine Mall. The gym runs a 12-week semester model for its Youth Ninja Squad program, built around a wristband level system (Levels 1 through 6) that lets kids progress from Tiny Ninjas (ages 4 and under) through Beginner, Intermediate, and Advanced tiers, plus an invitation-only Competitive Ninja Team that trains for regional and national competitions. Beyond the core youth classes, Maine Warrior Gym offers Wee Ninja classes for toddlers, a Homeschool Ninja & Parkour class, Adult Hybrid Ninja/Parkour and Advanced Adult classes for grown-ups, and walk-in Open Gym sessions for all ages and skill levels. The facility also hosts birthday parties, ninja camps, field trips, and a weekly 'Parents Night Out' supervised drop-off event paired with axe throwing next door at The Axe Pit.
