Become a ninja on the Upper East Side

Yes — completely free, and no card is required. Pick a time from the schedule above and come in. Once you join, classes come out of your plan as normal; the free one is the trial, before you commit.

You choose how often they come — once, twice or three times a week — and how long you want to commit for. Longer terms cost less per class. Everything is shown in the pricing section above, and you pay online right here — there is no separate account to create.

Little Ninjas is ages 1–2 as a parent-and-child class. Ninja Warrior runs 2–12, split into age bands so nobody is on the course beside a child much older or younger. Taekwondo starts at 3. If your child is on a boundary, tell us their age when you book and we’ll place them in the right room.

Comfortable clothes they can move in and hair tied back. Nothing else is needed — we provide all the equipment. For Taekwondo, a uniform comes later; the trial does not need one.

Yes — thirteen weekly sessions from 8 June to 4 September, ages 2–11. Full day runs 9am–2pm at $699 a week, half day 9am–12pm at $480, with early care from 8am. Siblings get 10% off.

We do, and they are one of the most popular things we run. Every party is set up around your child — the room, the group size and the timing all change with the booking, so we arrange them by phone rather than a fixed package. Call us on +1 917-639-3351 and we will walk you through what is included and what dates are open.

Yes. Playdates are a smaller, less structured way to use the gym — good for a group of friends or a quiet first visit. Times vary by week, so call us on +1 917-639-3351 and we will tell you what is running.

Tell us as early as you can and we will do our best to find another slot in the same week. Illness happens and we are not rigid about it. Give us a call on +1 917-639-3351 and we will sort it out with you.

Most families walk or take the subway — street parking nearby is limited, as it is anywhere in the neighbourhood. There are paid garages within a few blocks. If you are driving for the first time, give us a call and we will point you at the closest one.

For the youngest classes a parent is in the room with their child. For the older groups most parents watch from the side or drop off and come back — whichever suits you. Ask the coach on your first visit and they will show you where to wait.
