I've been training here for a few years. The gym has everything I need including excellent personal trainers. The gym also caters to high school athletes and even gives back to people with disabilities. The owner is wonderful and an excellent athlete himself. I highly recommend!

Critical Mass is the best gym I have found in my life. I have been training with Ken for over 5 years. Ken brings his “A” game when he comes to the gym everyday. His enthusiasm and level of energy is something that can’t be matched.Some say you lose muscle as you age, I say BS! In my 40s, I am stronger than I have ever been and I have done it safely and injury free under the guidance of Ken’s training. Before Ken, I didn’t know what a gada or steel mace was. Now, Ken helped me to be strong enough to swing a 56 lbs mace.Critical Mass is not your traditional gym. The equipment and most importantly the people set it apart. I have met nothing but good people in the gym and we follow each other on social media and support our respective fitness goals.As a bonus, Coach Ken is a great DJ and plays what you want to hear during personal training sessions.

Critical Mass has had an incredibly positive impact on my life and my family over the last six years I’ve been a member. It is the most positive, individual-focused, and family-friendly gyms I’ve ever been to. I’ve attended classes with various coaches and personal training with Ken Potis through pregnancy and two postpartum recoveries, always feeling safe training with coaches educated in women’s pre- and postpartum health. My husband now also attends class and trains with Ken, and my 6-year old daughter even joins for occasional training sessions. Thanks to the guidance and encouragement of Ken and Critical Mass my family is the strongest we’ve ever been. We have the energy and strength to keep up with our active kids and enjoy life to the fullest!!

Have been going here for almost a year and a half and happy I found this place! I take classes and personal training with Coach Ken. Really turned around my fitness and overall health. They really take the time to help you reach your full potential. Classes are awesome and different each day so you hit all the muscle groups. Classes are fun and great people to take the class with! Offers all the gym necessities as well including a series of machines, weights and more. Shower and lockers available in each bathroom. Super clean and friendly atmosphere!

I’ve been training with Ken for about 7 months and here is what’s up. I’ve been on and off lifting for years but my form has just been wrecked on some lifts, so, I didn’t do them lol. My squat was a disaster. I dreaded, I mean DREADED leg day because I didn’t really get the mechanics. 7 months in I am already in so much better shape than I’ve ever been, and my squat is functional and 50lbs heavier than I’ve ever done! At 44 years old, it’s killer to know I’m putting up more than I did in my 20’s. I can not recommend this place and Ken enough! My cardio ability is 10x what it was, which as a father of 2, it’s awesome knowing I’m taking actionable steps to be around for my family as long as possible. Everyone is included there, and the vibe is spot on. If you have been thinking about getting serious about fitness or need some tuning on what you already know, reach out today!

Training at Critical Mass is an absolute pleasure with a great atmosphere, knowledgeable staff and plenty of classes or personal training sessons available. The group classes can be as challenging as you want them to be. Everyone there is extremely helpful and members are there to motivate each other.

I have never felt better since starting at Critical Mass and training with Ken. I am not only reaching my goals but I am enjoying being part of the critical mass family. I am stronger than I’ve ever been and happy with all of my results. Ken’s training has given me a whole new perspective and I’m loving it!

Ken is simply an outstanding human being who also happens to be an incredible trainer/ mentor. I’ve never felt more comfortable or confident with going to the gym, but his intuition, deep industry knowledge and constant encouragement I finish our 1 on 1s with joy, pride, confidence, and desire to do more. My time going to critical mass is more than going through the motions of exercise; they are opportunities to grow on a personal level and find better mind/body connection. Not only have I seen incredible results and am the healthiest/ strongest I’ve been in a long long time. His commitment to seeing each client as a unique and distinctive person and creating thoughtful and creative solutions that meet their specific needs. Finding Ken and critical mass last year has changed my life.

I am beyond grateful for finding critical mass. This gym is unbelievably special in so many ways. I’ve been working out here for almost two years now and the changes in my physical and mental health are priceless. I guarantee you won’t find any other gym like this place. I’ve gone to all kinds of gyms up and down the east coast and nothing compares! The range of group classes are so inclusive to people of all ages and fitness levels. You feel like you’re part of a team and every member makes it a friendly and positive experience. So much detail and attention to form and each exercise is spent in every class by the coaches. They are always fun with a mix of strength, mobility and cardio. Coach Ken is also one of the only mace trained personal trainers in the area. Using the mace during classes adds a whole extra level of fun.I am super grateful for finding Coach Ken as a personal trainer. He really listens to his clients needs and goals and makes working out approachable for everyone. The amount of strength I’ve gained since working with him is amazing! I am super active at my job and it’s so important to me to make sure I am feeling my best physically and I feel better now in my 30s than when I was younger. I never thought I would be deadlifting over 300 pounds! This is all thanks to Coach Ken & John’s expertise and the environment they’ve created. I wish every woman had an opportunity to join this gym because it’s so empowering to feel this good! If you want to be your strongest best self this is the place for you.

I have been training with Ken at Critical Mass for about a year now and it has been the best experience I have ever had with fitness. Both the 1 on 1 training and classes are so fun, challenging and rewarding. The environment is so encouraging it feels like you are there with your favorite friends and family, training there has easily become the highlight of my day. This space has given me confidence, happiness, friendships, and strength, both mental and physical. Ken is a super human customizing every workout for each client of his, playing scheduling Tetris to get us in (often for me at the last minute) and curating the best experience. It is impossible to leave here not feeling on top of the world. I wish I could give Critical Mass 10 stars for all it has given me.

If you’re looking for a gym to help you become a total badass, Critical Mass is the place for you! I’ve been doing personal training sessions with Ken & attending group classes here for almost 2 years and it’s changed my life! Im the strongest I’ve ever been, have lost unwanted weight and gained so much confidence in myself. Coach Ken is extremely knowledgeable in proper technique with several styles of lifting and can also help guide you with your nutritional goals. Whether you’re an experienced athlete or just starting your fitness journey, critical Mass & coach Ken are who you want on your side!

I moved an hour away from Red Bank, but continue to come to Critical Mass three times a week rain or shine. Why? Because this is a special place. Their commitment to personal development of their clients is unparalleled. Trainers at Critical Mass are genuine and caring. They don't just physically train their clients, they mentor us. This is altogether a different level. What gym has a senior program and teen athletics under the same roof? I became athletic at the age of 50 with the guidance of my trainer Ken. And I am not alone here! Average men and women become stars. You can't put a price on this! Thank you, Ken and Jon!Yana
