Our Location

On Your Mark NYC is located in the heart of Manhattan, on Park Avenue and 30th st. We are on the lower level, inside Structure Personal Fitness.

Our gym has state of the art fitness equipment for all types of workouts. There are separate men's and women's bathrooms with showers and lockers. Our private treatment room is situated inside the gym, giving us and our manual therapy clients quick and full access to any gym equipment when needed.

Having our own treatment room inside the gym also enables us to meet with, stretch and offer manual therapy for our personal training clients.
