What is Ninja

Ninja Warrior is a mix between gymnastics, parkour, and playground. Here we learn to do monkey bars, swing from bar to bar, gain upper body strength and grip strength. On the floor we work on balance, jumping, precision landing, and body control. 

is this for me or my child

Like every sport you try, it takes time to learn the basics and get better. No prior experience is required. If you are new to the sport, we will teach you how to swing, best way to monkey bar and body control. Most importantly, we teach confidence when trying a new skill. If you are experienced in ninja, we will challenge you to make you better.

We offer classes starting as young as 3 with a parent involvement. Kids ages 4+ can do class without a parent on the floor. Whether you're 6 or 60, you don't need experience to get started. We'll teach you the skills, build your confidence, and challenge you to become stronger. 

How do classes run

is my kid to young?

Each class starts with a 2-minute jog and 8-minute stretch. After stretching, we explain the obstacles we will try that day. The kids are separated into small groups to attempt each obstacle as many times as they can in 5 minutes. they will then switch to the next. The last 5 minutes are for running the warped walls.

Ninja is a very upper body intensive workout. It takes time for your hands and shoulders to get used to it. We generally see progress made after 4-6 weeks of training.
