Chi began his career as a personal trainer in Boston in 1998, a year after graduating from the College of the Holy Cross in Worcester, MA with a degree in pre-med. After splitting time training and working in hospitals and other facets of the health industry, he decided to fore-go medical school and turn his efforts toward personal training full-time. In personal training, Chi found something he loved, valued, and enjoyed, and that served to fulfill what he desired most in wanting to become a physician: the ability to help people. Sick patients are often treated with medicine after being diagnosed with an ailment, but Chi's observations while working in the health industry taught him that prevention was as valuable in keeping the body healthy and in strong physical condition. Ultimately, he cultivated this passion into a career in personal training, allowing him to both help people and enjoy his work.

Chi has worked with athletes of all levels to developed strength programs. He works with triathletes, USHL hockey players, nationally ranked athletes in tennis and has also worked with David Ortiz of the Boston Red Sox on off-season diets and strength and conditioning programs. Chi took his work international when he was hired to train Olympic athletes at the Athens 2004 summer Olympics. Chi has developed strength training and fitness programs for tennis, wrestling and martial arts. He has also spent time establishing fitness programs to improve speed, agility, power and stamina for the Optimum tennis program at Sportsmen’s Tennis Club as well as the B.M.C. Durfee High School Wrestling program. Chi uses his extensive background in the sciences, human physiology, and years of athletic experience to develop safe and challenging workouts for clients of all fitness levels. He is well versed in strength training, wrestling, boxing and mixed martial arts, and is also experienced in assisting clients rehabilitating from prior injuries and surgeries. Besides challenging his clients successfully on a daily basis, Chi finds ways to challenge himself to reach new heights. He is an avid practitioner of the Wing Chun kung fu system. He is a 5-time bench press champion and has been crowned champion in national all-natural body building competitions. He has obtained professional status in two organizations.

Chi's clientele roster includes men, women and children of different ages and walks of life, as well as seniors, athletes (amateur and professional). His clients come from a variety of professions, such as business professionals, housewives, and performance artists. If you are serious about fitness and want to make a change, Chi is confident that he can help you achieve your goals.

Over 3 years, Chi has changed my outlook on living life properly and healthy. When I first started with Chi, I weighed a hefty 225lbs and looked very unhealthy. I was lazy, ate bad foods and felt as if I was underachieving during my everyday activities. I found myself skipping a lot of classes, and would only stay within the confines of my house. My daily routine would consist of many hours of just chilling, eating...and going to sleep at ridiculous times. After a while of living like this, I found myself getting more and more depressed… Then I met Chi through a friend of mine and I was instantly sold. I wanted Chi Bang Abs, and I wasn’t going to stop till I got them. The gym is where I would take out my frustrations. I’m so hooked now thanks to Chi and he really transformed my body from a big 225 pounder to a solid 182 pounds of muscle/fat. I owe a lot to Chi for turning my life into a much healthier style of living. My energy is up and I’m always looking for new activities to get involved in like kickboxing, yoga, and running. All in all I cannot thank Chi enough.
Jeff Perricone, 25, Student
I have been training with Chi for almost a year, and in that year I have accomplished things with my body I would have never thought possible. I came to Chi last year very enthused to understand the proper way to get results from resistance training. We worked together four days a week and during those times we met he was always educating me on form, explaining why I am performing these particular exercises, as well as keeping me motivated on realistic goals. Working with Chi this year I have been able to really see drastic changes in my body as well as my strength and performance in the gym. This January Chi put me on a workout plan to get me very lean. We were able to get me down to 5% body fat. It felt great to see my abs! I am working with Chi currently this summer to put on more lean muscle mass. It is very difficult to stay one hundred percent motivated in the gym every workout, as well as design a balanced routine to meet realistic goals. Chi helps me stay motivated every workout, and sets goals that are achievable. I hope to continue to see what I can accomplish working with Chi.

Training with Chi has put me in the best shape of my life… he made me excited to approach my new healthy lifestyle. He never made me feel like I was "working" out, he always made it interactive and fun and challenging. Every day with him was different. I never thought I would ever think "time flies by" while working out, but it does. Chi is honest, dedicated and passionate, my relationship with him made me want to be honest with him about all the food I put in my body.
Joel Cutler, 50, VC Partner
I am a 50 year old guy who, for most of his life, was in reasonably good shape. For the last ten years I focused more on cardio than strength and flexibility, much because of lack of focus, but also because of an increasingly painful lower back problem. Two years ago I got into an accident and pretty much abandoned serious workout efforts. When I turned 50, I promised my wife and myself, to get back into the kind of physical condition needed to make sure I could be as healthy as possible for a long time.
A buddy of mine introduced me to Chi six months ago. I liked him from the start. He was serious, smart and professional. He tested my resolve to get and stay in shape before he committed to take me on. He made me commit to working out with him at least three times a week and a couple of times more on my own. He coordinated efforts with my physical therapist to make sure we strengthened areas around my previous injuries and do no harm as we got started. He made me set my own goals for the month, the quarter and the year. Six months later my strength and flexibility are back to levels I have not seen in the last ten years. Chi's focus on my "core" has improved my balance and coordination while he takes me through a rigorous workout. I have always been thin, perhaps too thin sometimes, and I have been able to gain a few pounds all in my chest and arms as wanted over this time. Equally important, Chi has pushed me hard without "breaking” me. His focus on strength, balance, muscular coordination and flexibility has made this all come together for me. Chi is just a great guy. He is professional yet still personable. He is prompt but understands when my crazy schedule requires occasionally moving around appointments. I have worked with a bunch of trainers in the past, none come close to Chi.
Meredith Otten, 34, Entrepreneur
I was nervous about working with such a prominent trainer who has such an impressive client list. I figured I'd be his last priority. I was so wrong! From day one, Chi made me feel like I was one of his most important clients. He pushed me hard at the gym, but he also made me accountable to him for exercise time outside our sessions. Probably the best part though was his constant monitoring of my diet and grocery shopping. He had me email him everything I ate and bought every day- and when I would complain about missing certain foods he helped me find solutions that were tasty and healthy. In 4 months I went from being a lazy out-of-shape MBA student to finishing my first Triathlon! Thank you Chi!
Kim Mateus, 29, Chief Content Officer at Mequoda Group, LLC
Since I've known Chi, he's been a constant source of positivity, encouragement and strength in my life. Chi and I worked together for about a year, but his knowledge and passion about exercise and healthy eating has stayed with me since our first meeting… I saw results within about 3 weeks, and I was only doing about 80% of what he was recommending initially… Every human being on the planet falls prey to negative thinking, whether it's about work, family, finances or health and Chi's presence helps relieve the bad stuff… you get a sense of how genuinely committed and passionate he is about helping other people. He combines the smarts of a doctor with the soul of a peace corp worker. Since working with Chi, I have seen more tone and definition, visibly less cellulite and lots more strength and endurance.
David Jankilevitsch, 22, Babson Student
I began working with Chi because I prefer the personalized service Chi offers compared to working in a big gym. It will be close to two years now and I have gotten back into shape from a zero start and have maintained and grown since… I feel better and more active… I sleep and wake up better and feel like I perform better at work. I’ve become stronger, gained muscle and my posture has improved. Chi is always accessible and has motivated me along each step. I would recommend him to anyone who wishes to enjoy their work out session more and to be able to push their bodies harder than they could alone.
Daniel Sullivan, 23, Suffolk Student
I have worked individually with dozens of trainers in preparation for, and during my Russian Kettlebell Certification. I have worked with numerous strength trainers in college and high school in addition to team coaches. I can say without hesitation that Chi has an approach that better assists me in achieving my goals than any of the aforementioned. When I first approached Chi, I sought to lose weight, gain cardiovascular endurance and muscular stamina to prepare for a Spring trek in Denali National Park. I was in decent shape at the time but my routine wasn’t focused. In less than two months he brought me into peak physical condition; but, in less than a week only, he had developed a program drawing from his vast kinesiological knowledge, which simultaneously prepared me for rock climbing, glacier travel, and skiing, all while wearing a 50+ pound pack at over 5,000 feet of elevation. Among the members of the group on the trek I had the most physical aptitude. I cannot speak for every other person on the trek, but I believe that my experience was the most enjoyable because I was able to adapt to a constantly changing environment better than the rest. From this description one might envision a trainer with the temperament and method of a drill instructor. I don’t think a drill instructor could have helped me prepare the way Chi did. Chi has a constantly positive and encouraging attitude. If you want to joke, he’s ready to joke around. He is always serious about training though. I am tall and lean and have not made serious gains in strength quickly in the past; Chi has found ways to adapt the program time and time again to make faster gains than I have ever made, and I am constantly surprising myself. I have never worked with a trainer that has had such a grasp on bringing out the athlete in any person.
John Domolky, 21, Boston University Student
Working with Chi has made an enormous difference in my level of fitness and overall diet and health. Chi gets results and is constantly adapting my work-outs to maximize my potential. His experience is unmatched and I would highly recommend him to anyone interested in taking their body to the next level. I had worked with trainers in the past that would just hand me a plan and expect me to follow it. Chi is intimately involved every step of the way, effectively guaranteeing results. I'm now almost at 8% body fat, down from 15% when we started. I've also improved my bench by 75 lbs.

I am a certified group exercise instructor as well as a certified personal trainer. I have my Bachelors in Health Studies and am currently studying at Boston University to receive my Doctorate in Physical Therapy. I have taught group aerobics classes ranging from indoor cycling to cardiokickboxing and all the muscular conditioning classes in between. Through my studies, I have acquired a vast knowledge of human anatomy and bring all aspects of this knowledge into my training style. From nutrition to strength training or weight loss, I will help you exceed your personal goals by pushing you beyond the limits of what you perceived is possible.


Travis Conner, 24, Audit Associate at PricewaterhouseCoopers
A friend recommended me to Nicole, saying that she was an outstanding motivator who had plenty of knowledge and enthusiasm to help me reach my goals. Nicole greatly exceeded my expectations, not only was she able to motivate me to get back in shape, but her knowledge of various exercises allowed me to gain my desired results in a time efficient workout that fits into my busy schedule. Not only does Nicole have a great intelligence regarding muscle growth and weight loss through intense training, she also knows a lot about nutrition which I’ve learned has a tremendous effect on the results of my workouts. Nicole helped me achieve a smaller waist size, as well as better definition in my arms, chest and back. She sets herself apart from other trainers in the fact that she gets to know you and understand your personality so that she can motivate way you in the best way possible. I would highly recommend Nicole to anyone I know as she has the ability to train anyone of any age, gender, and physical capabilities. She is not only a genuinely nice person, but she also has a great sense of humor and an unbelievable work ethic. I truly enjoyed training with Nicole and I can only hope anyone else who needs a trainer gets Nicole, I really appreciate all that she has done for me. Thank you Nicole!
Shannon Carlson, 24, Graduate Student at Boston University
I began looking for a trainer a year and a half ago when my frustration towards losing weight had reached its peak. I had been working out consistently with no results and was ready to give up altogether when I started working with Nicole. She taught me a whole new way of working out, circuit training, which both cut my work out time in half and kept the work outs new and exciting. In addition to those benefits I finally starting feeling as though my efforts were paying off. If it wasn't for Nicole's innovative exercises and encouragement I don't think I would have been as successful at losing the weight and keeping it off. Nicole is both a great trainer and a great support system, which I believe is truly necessary to reach your goals when it comes to exercising. I would recommend her to anyone that needs to spice up their current routine or anyone who needs that extra motivation that having someone like Nicole definitely provides

Kristina Stanley,44, Beth Israel Fundrasing
I started training with Justin late summer 2010. At the time, I was concerned about a doctor prescribed medication I was taking that made me feel extremely lethargic and tired. I thought maybe if I worked with a trainer, I would have the motivation and help I needed to feel better and healthier while I was on the meds. Turned out to be one of the best decisions of my life. Justin helped get me through those long months on the medication, and I suddenly found myself with muscles I didn’t know I had. It was amazing to literally see myself stronger... with more endurance... more toned... less tired... clothes fitting better and looser. Also amazing was I found myself feeling better emotionally and I gained a new confidence. I’ve been off the meds now for quite some time, but I’m sticking with my trainer. One of the great things about Justin is that he adapts his immense knowledge of anatomy and human movement to suit my individual needs. He knows every bone, every muscle, every blood vessel, and more often than not, I’m getting my own anatomy and physiology lesson when I train with him. He’s very good at crafting motivational interventions which are specific to me. He knows just how to really push you when you really need it. Although there are times I'm fairly sure that what he's asking me to do will quite possibly kill me, it hasn’t happened yet – I just keep getting stronger and stronger.
Bruno I. Rubio, 50, University Professor
I usually go to the gym every day; my favorite activities are cardio and yoga. Although I’m in good shape, I knew my fitness routine was missing something. Before I started training with Justin, I had zero motivation to work out with weights. I was unsure about how much to lift, how many reps to do, what the correct form was, etc. I was also afraid of injuring myself. Justin gave me a new perspective on weight training. He’s so knowledgeable about anatomy and movement functionality. During our sessions Justin is attentive and encouraging. He also spurs me on when he thinks I can safely handle the challenge. Now, I actually like lifting and I’m breaking personal records on a weekly basis. Thanks Justin.
Greg Workman, 30, Medical Device Rep
I hired Justin through Boston's Chi Bang Bodies in 2010. He keeps me coming back because I enjoy spending time in the gym under his direction and love the results we've achieved. His knowledge of fitness, health and nutrition are unsurpassable. It is without reservation that I recommend Justin to anyone serious about achieving their fitness goals.
Justin Zompati, 28, Sales Associate
I recently sustained a major sports injury this past year that required surgery. Without Justin's help and coaching through the recovery process, I don't think I would be as active as I am... this early into it. He has an exceptional understanding of the Muscular & Skeletal systems of the human body. Justin has taught me how to stay injury-free moving forward, based on the analysis of my life's physical activities. He is very easy to communicate with, and is very passionate to helping his clients.

Chi and his crew are consummate professionals, with a great deal of knowledge and passion for their business. They have been extremely welcoming and I feel that they truly care about my results, with constant communication and encouragement.

I can wholeheartedly recommend Chi Bang Bodies, you will not find a better training staff in Greater Boston.
