CrossFit® Stealth: Opinions

5/5 (17 Opinions)
Joe M 2 years ago

Fantastic experience: Crossfit Stealth is a wonderful Crossfit Gym! Location is in the heart of New Brunswick minutes away from Rutgers Campus! This was my first Crossfit Box since starting 2 years ago and I cannot express the gratitude I have for coaches Matt and John. They have pushed me in ways I never thought was possible. They will help you reach your goals whether it be losing weight, getting stronger, or just overall health. The community is second to none. I can honestly say that the people that I have met here will be life long friends. If you are in the area and looking for a challenge do not overlook Crossfit Stealth!

Fantastic experience: CrossFit Stealth is THE place to go for new or current crossfitters! My experience here has been truly amazing. I started CrossFit looking to try something new and get in shape, and I ended up gaining a whole group of supportive friends and a new outlook on fitness. If you are ever in the area definitely drop in or, for newcomers, try their free class!

Fantastic experience: Crossfit Stealth is a great Crossfit box in the New Brunswick area. All the coaches are very well prepare and all the people you get to work out with are always great and will push you to do you your best. They're very well equipped as a box an classes are with a decent amount of people to coaches ratio. Great place to train and get fit if you're in the area!!

Fantastic experience: First.Better.Different. CrossFit Stealth was the first CrossFit box (gym) in Middlesex County. Since day one, CFS' promise has always been to deliver the absolute best training experience for all athletes. From newbie to experienced, fit to not so fit, CFS delivers high quality training for all age and ability levels. The CrossFit program has proven time and again to produce real results with lasting value. CFS has the ability to get you where you want to be. CrossFit Stealth's coaching staff is experienced, knowledgeable, and dedicated. The coaches at CFS continually strive to educate themselves and improve their coaching knowledge by staying current with the latest certifications offered. Their experience along with their thirst for knowledge is what separates the coaching staff from the rest. With two locations in central Jersey you have the ability to go to both locations to train.

Fantastic experience: If you are looking to work on your form, build confidence, meet other people, have fun, or a combination thereof, please consider joining CrossFit Stealth. You will have access to three local Stealth facilities, the ability to engage with multiple great coaches, and an opportunity to meet down-to-earth people. They also have programs that are designed to improve your nutrition and an "Athlete's Club" if you are looking to get to the next level. My favorite moments were participating in local 5Ks with the Stealth team and attending the 5PM class. They have other outside activities that are great to become involved with too. Overall, I would highly recommend CrossFit Stealth to anyone.

Fantastic experience: Dropped in out of town and was instantly welcomed by the owner, coach, and community. Bobby lead a great class and Jon, one of the co-owners, joined - which in my experience is all you need to know about a CF box and ownership. If the coaches and owners take class with the community, it's a great sign and this was no different! New Brunswick is lucky to have this community of fitness and I encourage people to come try it out!

Fantastic experience: I had one main goal when I started my journey at Crossfit Stealth; it was to get fit and stay fit. I not only fulfilled this goal, but I also got to be a part of an amazing community. Matt, John, and all of the coaches there are truly amazing! This is absolutely the place to be!

Fantastic experience: Crossfit stealth is an amazing gym. Firstly, workouts are awesome. This is my first time with crossfit and the new movements can be a lil over whelming in the beginning but one can surely reap the benefits if you hang in there. Saturday and long weekend workouts are extra fun. Secondly, both Matt and John are great owners and coaches. They are always helping and really nice. The fact that they allowed the customers to borrow gym equipment and conducted zoom classes every day during quarantine is a testament to their dedication.

Fantastic experience: Crossfit Stealth has provided a great Crossfit community that truly cares about your progress as member. Not only is there top-notch coaching, but the encouragement from all the coaches and the community makes going to classes that much more exciting! Definitely drop-in to this box if you are in the area.

Fantastic experience: I've played recreational sports all my life, but I can say that having joined Stealth, this is the healthiest and strongest I've ever been. It's a great environment with a great staff of coaches who help you step by step achieve your fitness goals, whatever they may be. The stealth community is super supportive and an overall great environment to be a part of.
