This gym is amazing. Great equipment and very knowledgeable staff. When you visit you feel right at home and the owner is the best!!! Keith has such a good heart and is passionate about health and fitness. The hours of operation are also very convenient. Super clean facility with positive vibes. Loved my week trial and am excited to be a member.

This place is the absolute best - what a local gem. Training with Deena has been such a game changer for me. She's been working with me closely to get in shape, guides me with nutrition, and keeps me motivated. Deena is very knowledgeable, especially geared towards women's health/fitness. She always has such positive energy, and I genuinely look forward to our sessions. Phil and Keith have also been integral to my fitness journey at Kriptoknight-X. They set such a solid foundation for me and are very experienced and adaptable - adjusting workouts tailored to my personal needs. The gym itself has the best energy and a true community feel. Every time I walk in, I leave in a better mood. Couldn’t recommend the Kriptoknight-X team more!

I’ve been working out at Kriptoknight for almost two months now. I joined for the personal training and have been doing a combo of that with Philip and the Group Training with Keith. Both are incredibly knowledgeable and push you to your limits, but not over. The time flies and I am already stronger. The community is an added bonus, everyone is friendly, and it’s totally judgement free. I cannot recommend this place enough.

This neighborhood, small business gym is the real deal! What sets Kriptoknight apart from the other gyms that I’ve tried in the Greenpoint/Wburg areas is the focus on community/ fostering a friendly environment (which I find is pretty hard to come by in this transplant-heavy neighborhood). Nothing beats walking into this gym and being greeted with a smile. It is clear that Phillip & Keith have so much passion and are a wealth of knowledge about what they do- from stretching, exercises, proper form, nutrition/diet, etc. I personally attend their group training classes and highly recommend them. For anyone on the fence about this place, highly recommend just walking in and taking a look! 🙂

A year ago, after emergency surgery, I suffered nerve damage in my leg, affecteing my walking ever since. 4 sessions with Keith and there's been a huge improvement! His one on one in the rehab exercises has been invaluable. He's guided me through the machines that are strengthening my legs. Keith, and Phil also, have affected my quality of life for the better. In their patience and encouragement, motivating you to push harder, they are unsurpassed. I can't praise them highly enough.

So far, joining Kriptoknight-X has been a transformative experience for me. In just a couple of months, it feels like I've become part of a supportive and motivating community. The facility is small, but still manages to house state-of-the-art equipment, a variety of classes, and a clean, welcoming environment.

The real standout, though, is the personal training team. Every trainer is not only highly skilled but also genuinely invested in helping you achieve your fitness goals. They take the time to understand your individual needs and tailor their approach to ensure you see progress. Their encouragement and expertise make every session challenging yet rewarding.

Additionally, the gym offers a diverse range of group classes that cater to all fitness levels. Whether you're into circuit training, pilates, or step classes, there's something for everyone. The instructors are enthusiastic and knowledgeable, creating an energizing atmosphere that keeps you coming back for more. Classes tend to be on the smaller side, so you end up getting great feedback, almost like a personal session.

The sense of community here is incredible. Members support each other, and there's a real camaraderie that makes group workout sessions enjoyable. I've met so many wonderful people who inspire me to push my limits and stay committed to my fitness journey.

Overall, Kriptoknight-X is more than just a place to work out—it's a place where you can thrive, surrounded by people who genuinely care about your success judgement-free. I highly recommend it to anyone looking to improve their fitness and become part of an amazing community.

I started training with Phil 18months ago, he has guided me through my fitness journey and supported my goals through my sessions with him. Having the space at kriptoknight has been advantageous due to the equipment, space and room to get creative with the workouts while exploring new activities to push me further. I often feel intimidated in a gym type environment but that’s not the case here, whilst I need the motivation of a trainer (thanks Phil and Keith)- if I didn’t I would happily work out here alone too.

The environment is welcoming and friendly. The gym is clean, the group classes are great and seeing everyone do their thing is encouraging. This so far as been a great experience for me and I look forward to continuing to work with Keith in achieving my goals. If you’re looking for someone who’s understanding of what your goal is/what you’re trying to do and will help get you there, then Keith is the man and Kriptokinght-X Exercise is the place to be!!! I love it here!!! You put in that work, but I must admit….you feel good at the end of it. Thank you Keith, I appreciate you!!!

Keith is an awesome trainer! Coming from someone who used to hate working out...he works with everyone's skill-level and does not make you feel bad if you cannot complete a certain exercise routine. He works patiently with every client's individual skill-level with a goal of making you stronger...and you eventually end up enjoying the work-outs. He is meticulous with his group-training sessions as he takes time to plan the workouts geared to his clients! Kriptoknight-X Exercise & Wellness Center has become a part of my "Self-Care" routine! He constantly encourages all of his clients to challenge themselves. It's worth it.
