Testimonials
Tony is an exceptional trainer. There are numerous trainers out there but it is rare to find one with his skill set. The workouts with him are the best. We don’t do the same exercises every time. He is constantly changing up what we do to get the best results and not allow the muscles to get used to routines. He doesn’t focus on how much weight I can lift but rather adhering to perfect form to get the best results from each exercise and rep. Our workouts are intense. Tony explains why we are doing each exercise and the overall benefit. He is a stickler for a clean diet and explains to me that I can not get the best results without eating well. Lots of clean proteins, good carbs and veggies. We constantly talk about goals and how to reach them. I turned 65 today. I used to primarily be a long distant runner and triathlete. If I had followed that path over the last 10 years I would likely have had at least one knee surgery. Instead this is the best shape I have been able to attain in a long time. Maybe ever. Tony works hard himself and is inspirational to the people he trains. I am lucky to have found such an excellent trainer and hope we can train together for many years.

Tony was my personal trainer from 2019 to 2021 and played a huge role in helping me get back into shape after surgery and several injuries. He is not only an excellent trainer but also a genuinely great person who knows how to challenge and motivate his clients. He pushed me outside of my comfort zone and helped me build the confidence to try exercises I was initially afraid to do. His knowledge, encouragement, and guidance made a significant impact on my fitness journey. I now live in Florida, but whenever I’m back visiting, I still make time to train with him. I highly recommend Tony to anyone looking for a trainer who truly cares about helping you succeed.

Tony,
Tony epitomizes exactly what you want in a personal trainer; someone who practices what they preach. When I first started working out at Renegade Fitness, I needed to learn how to lift properly, how to diet correctly, and how to discipline myself to achieve my goals. I watched Tony for several months. I observed how he talked to his clients, listened to his clients, showed them the proper way to do the exercises, and the advice he gave in terms of how to properly diet and to train for consistency. I saw Tony utilizing the same practices that he gave to his clients in his own personal workouts. I then knew Tony was exactly the personal trainer I needed.
I hired Tony to be my personal trainer.
I can not thank him enough for the knowledge he has given me as I have been working out consistently for six years. Without Tony’s inspiration, guidance, and answering all of my endless questions, I would have quit years ago. Six years later, Tony still answers all of my questions and offers advice.
Thank you Tony for not only providing me with your expertise, but for always willing to listen and help me alo

Tony Costello is hands-down my favorite trainer I’ve ever had. From our very first session, he brought such a positive, motivating attitude that completely transformed how I approach fitness. His energy and encouragement have inspired me to make this a lifelong journey, not just a short-term fix.
After dealing with back surgery issues, Tony smartly focused on classical muscle training techniques that helped me build strength safely and effectively while compensating for my limitations. Thanks to his expertise, guidance, and personalized approach, I’ve made incredible progress in my recovery. I genuinely owe my results—and my renewed confidence—to Tony.
If you’re looking for a trainer who truly cares and gets results, Tony is the one.

When I first met Tony, I was incredibly out of shape and honestly pretty discouraged. I had tried diet after diet, chased quick fixes, and never seemed to find anything that truly worked for me long term. On top of that, I had never really spent much time in a gym, and I was intimidated by the idea of working with someone who was so obviously dedicated to health and fitness.
That intimidation disappeared almost immediately after meeting Tony.
What stood out to me wasn't just his knowledge of fitness and training—it was how much he genuinely cares about the people he works with. His background in psychology gives him a unique ability to understand the mental and emotional side of the journey, not just the physical side. He knows how to listen, how to encourage, and how to help you navigate the struggles and challenges that inevitably come with trying to improve your health.
Tony has helped me become the strongest I've been in my entire life. More importantly, he's helped me become a better version of myself. He never shamed me for having cheat days or slipping up. Instead, he taught me to be kind to myself, learn from setbacks, and stay committed to the bigger picture. His approach is built on consistency, encouragement, and sustainable progress rather than guilt or punishment.
Even when I took a break from training and eventually returned, Tony welcomed me back with open arms. There was no judgment—just support, guidance, and a clear plan to help me regain my strength and refocus on my goals. That experience alone speaks volumes about the type of person he is.
If you're looking for a trainer who truly cares, who understands that fitness is about more than workouts and meal plans, and who will support you through every stage of your journey, I can't recommend Tony highly enough. Working with him has been one of the best investments I've ever made in my health, my confidence, and my overall well-being.
Warm Regards,
Grant
I've worked out in gyms for several decades and wish I had met Tony much earlier. He tailors his fitness and nutrition programs to the needs of each client, whether that be bodybuilding, athlete training, or, as in my case, staying strong and healthy as I age. Every week he adjusted our workouts as I got stronger, and I not only lost weight and gained muscle, I was able to actively travel, hike mountains, and haul heavy suitcases up and down stairs again. When I had a shoulder injury, he quickly modified exercises so I could train safely and consistently. I can't recommend him enough!

I have been working with Tony for about 6 months now and i couldnt be happier! He listened to my goals and tailored a program specific to my interests in various types of training, my abilities, and my desired results. Tony makes each workout fun and challenging, and always helps perfect my form to make sure im really getting the most out of each movement. Tony is kind, encouraging, and extremely knowledgeable. I love that he pushes me and he has been such a pleasure to work with. Thanks Tony!

Tony is the best there is at what he does. Not only will Tony transform your body with workouts and nutrition guidance, but he will also improve your entire mental game. Having both myself and two of my sons train with Tony, I can confidently say you won’t find a finer personal trainer, coach and friend anywhere.
Jeff S.
I began working out with tony as my personal trainer about 2 years ago after hitting a wall regarding my fitness goals. I have been a life long work out and sports enthusiast however, as I get older I’ve notice that my workouts and my nutrition patterns continue to push my goals in the wrong direction. After starting with Tony that is no longer the case. I look and feel better than ever before. Tony redefined the way I work out, my diet, and most importantly, how I see myself.
Ellen D.
Working with Tony has been a game changer. He helped me understand that building muscle in the right areas isn’t just about fitness, it’s about creating shape, confidence, and a more youthful appearance. Tony is incredibly educated, passionate, and most importantly, he lives the lifestyle he teaches. His results speak for themselves. There’s nothing worse than a coach who doesn’t represent what they sell, and Tony is the exact opposite. It’s no surprise his clients stay with him long after they’ve achieved their goals. I highly recommend him.
Carolina Priest
I first met Tony in 2011 at a small private gym in the Northwest suburbs of Chicago, he was the first (and frankly only) one to come greet me at the door while I awkwardly stood there, intimidated by the machines.
Since then, I have tried other trainers but none compare. He embodies the values he promotes, and can explain the science behind it too.
Truly a one-of-a-kind trainer that I will 100% be staying with for many years to come!
Kristen F.
After a car accident and 7 weeks of physical therapy my physical therapist recommended that I look into getting a personal trainer. She noticed that the work outs I was doing I kept getting out of proper position. After my initial Consultation with Tony I was really excited to get working. Not only was he going to help monitor me during work outs so I dont re injure myself but he was going to help with a diet as well. I just completed 36 sessions with Tony and I feel like a different person already. His 20+ years of knowledge working in this field really shows. He genuinely cares about how you are feeling and sets you on a proper plan of success with health and fitness. I plan on being a long time client, thanks again Tony!

Tired of being tired all the time
Wanted to feel better and play better golf. Longevity is very important. With Tony you don’t just get a great trainer. You get a nutritionist, a psychologist and a friend. I’m very lucky to have found u. I got cancer twice in 3 years of working with Tony and flew through radiation and 30 sessions of proton therapy. There is a good chance if I wasn’t with Tony I would of not made it through.
Mike S.
I trained with Tony Costello from age 12 through middle school, and even afterward, for the past four to five years, he’s been a reliable friend I turn to for advice. My original goal was simply to learn lifting, but Tony helped me transform entirely. I went from a complete beginner that can barely lift the bar, to benching a plate and a half by 14. His structured, encouraging approach not only improved my strength but also my confidence in life. To this day, he’s always there if I have questions or need support. I’d recommend him to anyone who wants guidance and lasting growth.
Nolan C.
Working with Tony has been one of the best decisions i’ve made for my health and happiness. I started training with Tony in September 2025, and the difference he made in my life is incredible. By following the training plan he created for me, I’ve lost 40 pounds, built real strength, and gained confidence I didn’t think I’d ever get back. What stands out most about Tony is his knowledge. Every exercise, every progression, every part of the plan had a purpose — and you can feel that when you’re doing it. He explains things in a way that makes sense, and the structure of his program keeps you consistent and motivated. I’m happier, stronger, healthier and far less stressed than when I started. His training truly works, and I’m grateful for the impact it’s had on my life.
Gini
My journey with Tony started in 2005. At first I had doubts, but once I made the commitment it was game on. He didn’t realize the type of determination I had. From the beginning Tony was detailed with everything he did. Started with the basics and then turned the heat up! You could tell Tony cared and wanted to bring change and results and at that point my body transformed to an unstoppable machine. I could not have had a better trainer teaching me what I have learned throughout the years. I have learned a lot about my body and how by eating the right foods it makes a difference. It definitely takes a lot of work but when you look in the mirror you can say say to yourself that it was so worth it. Tony is not only an excellent trainer and highly skilled with the services he offers, but a great friend and that at times over the years meant more than anything.
Nico Scardino
I’ve been training with Tony since 2012, minus a couple years when I moved out of state for business. I was 52 when I started and had never done weight training. I was not specifically looking for weight training, more so just to get in better shape, but I am glad I found Tony. With his guidance, I have discovered how much I enjoy it, and the results have been beyond my expectations. His expertise, attention to form, and personalized approach helped me reach goals I thought were unattainable. I lost 30 lbs while simultaneously adding muscle mass, and my overall strength is probably top 5% for my age.
Every session is challenging but encouraging, and his programs provide a welcome variety. Beyond training, Tony provides clear nutrition guidance and practical lifestyle tips that make healthy habits sustainable.
His professionalism and positive energy keep workouts fun and safe, and he has been able to work around injuries I sustained outside the gym. I highly recommend Tony to anyone serious about making real, lasting changes.
Pat S.
My husband and I have been training with Tony for four years, and the results have gone far beyond physical fitness. From the very beginning, he taught us that consistency and hard work, not quick fixes lead to lasting results. Tony has helped us improve not only our workouts but also our eating habits and overall approach to health. In our 40s, staying active and healthy is a priority, and Tony has been an incredible partner in that journey. He motivates us, challenges us, holds us accountable, and continues to help us find ways to improve. We trust Tony completely and are grateful for the positive impact he has had on our lives. If you're looking for a trainer who truly cares about your success and helps create sustainable lifestyle changes, we highly recommend him.

Tony is one of the best trainers I’ve had the privilege to work with. He does a great job of keeping me on top of my nutritional and exercise goals. He not only makes the exercise itself fun, but he also rotates in new exercises so my routine doesn’t feel stale. I would highly recommend him for both beginners as well as experienced athletes to achieve your fitness goals.

I first started trading with Tony when around 2005. That was my first experience with personal training. As life happened I was not able to keep up my sessions and tried to do it on my own. We were both a lot younger then. When I was finally ready to restart my fitness journey in 2019 I was able to find Tony once again and we restarted our journey. He’s a fantastic trainer. Strict on form, pushing you just enough to see those gains. Have you seen his pictures. You want a trainer that looks like a trainer. He also focuses on nutrition as well. Our sessions were my time to get out of my own head and leave work, home, etc behind and focus on me. Did I mention he has a psychology degree?
John K.
For the past three years, working with my trainer has been one of the best investments I’ve made in myself. He doesn’t just show up for workouts he genuinely cares about my progress and success. He keeps me accountable by tracking my nutrition, measurements, and muscle growth, making sure every step is moving me toward my goals.
Beyond being an incredible trainer, he’s been a great friend and constant source of encouragement, always pushing me to be stronger than I thought possible. His knowledge, dedication, and support have helped transform not only my physique but also my confidence. I couldn’t recommend him more to anyone looking for someone who truly cares about their clients and their results.
Carey B.
Working with Tony Costello has completely changed the way I approach fitness. As a competitive bodybuilder, Tony brings an incredible level of knowledge, discipline, and experience to every training session.
Not only has he helped transform my physique, but he has also taught me the importance of proper lifting technique and safe form. Before training with Tony, I often questioned whether I was performing exercises correctly. Now I feel confident in the gym, knowing how to lift safely and effectively while minimizing the risk of injury.
What sets Tony apart is his ability to tailor a program to your individual goals while providing constant encouragement and accountability. He takes the time to explain the “why” behind each exercise, helping me understand how to train smarter, not just harder.
Thanks to Tony’s guidance, I’ve become stronger, more confident, and more knowledgeable about fitness than ever before. If you’re looking for a trainer who genuinely cares about your success and has the expertise to help you achieve real results, I highly recommend Tony Costello.
Lauren Z.
I trained with Tony from ages 18–20, and it was one of the best investments I’ve made in my health and fitness. In just six months, I gained over 30 pounds of muscle, going from 150 to 182 pounds while getting significantly stronger and improving my overall physique.
To this day, I can honestly say I was the strongest I’ve ever been while training with Tony. His knowledge, programming, and ability to keep me accountable produced real results. I would highly recommend him to anyone looking to build muscle, gain strength, and transform their body.

I have been training with Tony for over 10 years. He is kind, patient, knowledgeable and a great motivator. I am now a senior and an avid golfer, he has kept me healthy and injury free for all these years. I feel we have built muscle, improved my posture and helped with balance. Most of all, I appreciate how he can adapt my workout to fit my needs and ability while pushing me to go the extra mile. Tony genuinely cares about his clients!

Tony is the best there is. The changes you’ll see both physically and mentally are beyond what you could ever imagine.

He is the first person I’d recommend to anyone trying to get a trainer and if I could go back I’d choose him every time.

Tony is a great personal trainer. As a wife, mother and working woman, I found my time with Tony very encouraging and supportive. I was able to lower my doctor's complaints about my cholesterol and sugar. Tony educated me in every day health and better life style. He was able to work with my limitations. Our family is greatful to know him.

Training with Tony Costello was a game‑changer for me. His approach is equal parts expertise, structure, and genuine care for his clients. Every session had a purpose, every program was tailored, and the results were real. Tony knows how to push you without ever compromising form or safety, and he brings a level of professionalism that sets him apart in the fitness industry. If you’re looking for a trainer who delivers measurable progress and truly invests in your success, Tony is the one you want in your corner.
Dean T.
Seventeen years ago, when I was in high school, I wanted to get into weightlifting. I met Tony and immediately knew I wanted to train with him. He was, and still is, one of the most knowledgeable people I know when it comes to fitness, lifting, nutrition, and understanding the human body. What I appreciated most was that I never felt like just another client. Tony genuinely cared about my progress and was always there to support me, push me toward my goals, and help me reach my full potential. Still to this day, I feel incredibly lucky to have learned from him. The knowledge, confidence, and habits I gained through training with Tony have stayed with me. Im also so grateful that our trainer/client relationship grew into a lifelong friendship. I couldn’t recommend working with Tony enough!
Tori E.
When I started training with Tony, I had absolutely no true understanding of fitness, nutrition, or how to properly take care of my body. Through his guidance, patience, and expertise, he taught me how to lift weights safely and effectively, eat healthier, and help me understand the importance of the foods I choose to put into my body. More importantly, I now feel like I have the tools to take care of myself, meet my goals, and continue making progress long-term. I'm incredibly grateful for everything Tony has taught me and would highly recommend him to anyone looking to improve their health and fitness.
Johnny D.
I was 63 and out of shape when I started working with Tony 6 years ago. We discussed my goals which are strength, balance, and continued mobility. Tony created a workout plan which includes stretching, free and machine weight training and bands.
He is able to adjust my workouts to accommodate any issues i may have, specifically pending knee replacement surgery.
Tony keeps my training sessions varied, interesting and challenging. Looking forward to continued training with Tony into my 70s.
Monica M.
