Claudio’s extraordinary knowledge of diet, training, and motivation together with his dedication, optimism, and tenacity earn my respect, admiration, and loyalty. He’s a champion bodybuilder who understands anatomy, healthy diet, and he extols the benefits of moderate diet and exercise appropriate to my goals. Over the past 7 years he’s been guiding, challenging, and encouraging me to better health and fitness while I’ve enjoyed both the program and the resulting success. His new fitness facility is spectacular: full of energy, enthusiasm, and the best machines and advice in personal training – just like the owner.

I have been to other personal training facilities in the past and all of them have been unproductive for me except for Achieve Fitness of North Haven. Claudio Boni is my trainer and with him I have been able to reach goals I thought would be impossible for me. I am about to be 40 years young and am in the best shape of my life thanks to Claudio’s meticulous training and extensive knowledge of the body and nutrition. I have lost 2 sizes and have been able to build considerable muscle in the short time I have been training at Achieve and I look forward to many more transformations. Thank you to Claudio for making the workouts so much fun. I can’t wait until my next session!

I am a physician and a client of Claudio Boni’s. I can, without reservation, recommend him as a personal trainer. I have worked with Claudio on a weekly basis over the past ten years. He is the consummate professional, intelligent and has a base of knowledge of the musculoskeletal system that is exceptional. He has, on more occasions than I can count, expertly ascertained the source of a particular pain/dysfunction that I am suffering from and corrected the problem for me. He is excellent in helping me with strength training; he listens closely and consistently helps me actualize my fitness goals. I have referred family, friends and patients to him over the years and all have had a very positive experience with Claudio. I cannot close without referencing his new personal gym, Achieve Fitness in North Haven, Ct. It is a gem. Newly opened with gorgeous interior, it has some of the best equipment I’ve ever worked out on. Four stars!!

Claudio is committed to my success and overall well-being.  He is mindful of the goals we have set (and keep tweaking) together and wants nothing more than to motivate me to get there.  He has extensive knowledge of human kinetics and nutrition; the guidance he has given me related to proper workout fueling and daily food intake noticeably increased my level of performance.  We work hard together, and I leave every training session feeling strong and happy.

I hate gyms. I could never find any kind of pleasure in working out until I met Claudio, whose creativity, attention to form, and superlative knowledge of the body and nutrition got me hooked. Now I can’t wait to train under his supervision. Claudio challenges me just enough to keep a perfect balance between steady progress in strength and flexibility, and the desire to constantly get better at what he teaches me. He is friendly, patient, answers all my questions, and pays close attention to all the signals sent by my body during training. Thanks to him, training for fitness no longer feels like a drag.

I cannot tell you how much Claudio has made a difference in my life. In the past several years, I have had both my knees and both hips replaced. Then, last January, I had a spinal fusion in my lower back. Claudio has helped me both before and after each surgery. He is able to customize a program for what I am able to do at any time. Now, we are working on just getting me stronger. I love that I cannot predict what we will do as Claudio continually challenges me with new and different exercises. Without his guidance, I cannot imagine being able to function as well as I do, including hiking and scuba diving. I am looking forward to playing golf again this spring as soon as I am cleared by my doctor.
