My kid spent 5 weeks here and he is now, stronger, faster, and more lean, but most importantly, he had so much fun learning new things and meeting new friends. The owner is incredibly polite, knowledgeable, and seems passionate for his work.

Great place for kids to learn some sport training skills while having fun! The staff is AMAZING . Its close and convenient for us and my son loves go there. Can’t wait for the Summer @ GRIT

My 4 & 6-year old thrived in a very safe environment and made lots of friends in the 2 weeks that they attended. They needed this badly! I’m so glad that my wife convinced me to send them. I have noticed significant growth in my youngest’s communication skills. Thank you Coach Peyton and Staff for providing such a wonderful experience!

Peyton the owner did an amazing job at this place! My fiancé’s little brother goes there for the gym and he never wants to leave! Coaches are great and the kids exercises are very healthy and fun!! Very clean place and highly recommended!

This is a great place-our kids love it. They are very accommodating, friendly, and stimulate our kids at all skill levels. We appreciate all the variety of activities-from parkour to skateboarding, professionalism and flexibility the school offers.

Both my 9 and 7 year old enjoy the parkour classes at GRIT so much! They can’t wait for the next class. In addition to being fun, the class is physically intense and challenging. The kids come back quite exhausted, very hungry, and absolutely happy! It’s a perfect afterschool activity.

We celebrated my son’s birthday 2 years in row now at Grit ! Hosts were great with children and very hands on in helping us decorating ! Everyone had the best time ! Totally recommended for birthday parties in downtown area .

My daughter has participated in Grit’s summer camp and after school program—and both provide a safe, fun, high-energy experience. The staff is really attentive and supportive. I’m grateful our community has Grit as a home away from home for active kids.

This is hands down the best place to groom your kids for sports and athletics! The coaches are experts and truly interested in making sure the kids are learning and doing things with the right technique. The owner Peyton, is always around to answer any questions and provide recommendations. My son loves the Parkour program he is attending!

Fantastic place for all sorts of kid's athletic and academic classes and I've had my son's birthday party there twice now. Amazing and friendly staff, great ownership and a safe and place for your kids to have a great training session or an evening out.

This was a perfect Birthday Spot for our son’s Ted 9th Birthday. Grit has a set system! They have a list of multiple games( we chose nerf gun battle and floor is lava) each game can be about 30 minutes. And after, if there is time left, they can have a free play. Table, water, juice, balloons were setup by staff. There was two people who assisted us and took complete care of the process and games. All we did was order pizza delivery and cake. And after all kids went to the local park across the street.

We’re huge fans of GRIT! We started off going to parkour classes for my 4 year old and we got hooked! They offer a great variety of classes (my son is currently doing basketball!) and the timing always coordinates well with school. We love their holiday camps for when school is out and recently the kids asked to attend one of their “Kids Nights Out” and they had a blast and came home asking me when the next one was. My son had one of his birthday parties there too (they were so accommodating and my son enjoyed every second.) We also have done their adventure summer camp three years in a row! We’ve felt part of the GRIT family and can’t wait to see what other programming and updates to the facility they do! Five stars for GRIT and we’re thankful to have them in Jersey City. ❤️

Our son is obsessed with all the activities and offerings with GRIT. We have been doing the summer camp and love all the activities they offer. They keep the kids active and have fun all day. The counselors and staff are kind and really take the time to connect. That means so much as a parent, it feels good to know my son is in good hands all day. Love that they offer skateboarding as an activty!! Major plus.

We’ve been going to Grit for at least three years now, taken several of their classes, gone to numerous birthday parties there and hosted three of our own. The space is perfect for athletic kids who need space to move and play, especially when it’s less than ideal temperatures outside and there is plenty of space for parents to socialize and relax off the gym floor. The coaches are very attentive both when teaching a class and when assisting a birthday party host (shout out to coaches David and John for this weekend, you were AMAZING and made my son’s party the success it was). The owner (Peyton) is a delight as well as every employee I’ve encountered there. My son is currently obsessed with their ninja parkour class, and I love how his coach knows exactly how much to push him - he doesn’t go easy on him and my son responds well to it. Anyway if you’re thinking about booking a party or taking a class I can state for a fact that there’s no other gym quite like Grit for kids who have outgrown most play spaces but aren’t ready for (or don’t want) a dumbbells and treadmills only type gym (or just want a fun place to celebrate with friends). Check them out!

My 7 and 10 year old boys have been loving Grit since it opened almost 4 years ago. They’ve done summer camp at the primary location and Hamilton Park, classes, birthday parties, and parent-night-outs. If Grit offers it, we’ve done it. And I cannot recommend it enough! They do a fantastic job of keeping the kids active at all of their events. I like that their parkour classes/camp are a lot of fun for the kids but also teach real life skills for agility and safety while fostering independence. Do you know the safest way to jump over a bench or get down from a wall? Well my kids know now, thanks to Grit!
