“..it's really changed my life and my ability to be able to be functional on a day to day basis.. Danny runs a phenomenal program and has a great team. So, you can benefit regardless of what your goals are..”

- Patrick -

“ I'm able to do, like, haul the 35 pound bag of dog food from the porch down to the basement and things like that, you know, potting soil. Just being able to do that without needing help has been wonderful. Emotionally, it's very empowering. It's very empowering to come here and lift heavy stuff and just feels amazing. It's a mood booster. It's an energy booster. And it's awesome.”

- Jennifer -

“I feel so good and so strong in my day to day life. Just basic things that were exhausting, like picking up a one and a three year old in and out of the car and carrying them both, sometimes up and down the stairs. Those things feel easy and it just makes me feel so capable.. ..And so I have like a high level of confidence.”

- Crystal -

“My back feels better. I have better balance. Upper body is stronger. My endurance is better with everything that I do, from yard work to working in the kitchen. It's amazing. They all encourage you. It's a very comfortable environment for me here.”

- Patti -

“My trainer, I'd say not only is he really good in the mechanics, but he can read a client. My husband and I train totally different, and yet he can get really good results from both of us because it's more reading who we are as people and how we best respond to correction or challenge or pushing. So I feel like anybody who comes here is going to get that same care.”

This is a bit long. I ask that you read to the bottom if you are sincerely interested in outstanding training. Especially if you are older and have some physical issues. I began training with Danny in August 2023 at the age of 64. At that time I weighed nearly 300lbs. My overall physical condition was a mess. I had already had a spinal fusion - L5/S1 (1998), two total hip replacements ('14 & '17); total right knee replacement ('15); subsequent debriding of the same knee ('17) due to excessive scar tissue. Shortly before joining DG Fitness I had total replacement of both shoulders in April & November 2022. Though my physical condition was mechanically "repaired", it became secondary to my mental approach. Though I had completed physical therapy (×2) and had been cleared by my surgeon, I was hesitant to do anything beyond physical therapy exercises. I had been a successful competitive power lifter (1600 lb total at 242lbs) and always willing to step up to the next challenge. For the first time in my life I was actually afraid to lift. My flexibility was nearly zero. I used to joke that I looked like a giraffe at the watering hole when performing floor exercises. Danny conducted a full assessment of my condition and began a program focused on regarding flexibility and strength within my capabilities, to start. As the training began to progress, I had a total left knee replacement July 5th 2024. I continued with the upper body regimen during PT. Shout out to Dr. Joe for getting me ready to resume the lower body routine. Upon returning to full body programs, Danny took special care to avoid injury, but concentrated on strength to avoid backsliding. In no time we were moving forward. It is March of 2026. I am 67, weigh a firm 267, and haven't been in such good shape in over a decade. Danny is VERY knowledgeable and never stops studying and researching. This was very evident and critical working with the Tin Man. Modification became essential. His patience, and understanding that fitness is a total mind, body and spirit endeavor, guide his approach and hands-on training. I wanted to quit many times. Danny kept me going. I'd stall and we'd switch things up. I'd start to feel good about certain gains and he would continue (cautiously)...this has been vital to my mental & spiritual approach. Lastly, Danny is a good man who cares deeply about his clients. I am blessed to have him in my corner and plan to continue on for years to come. Respectfully, John G.

We are so grateful we found Danny Gustin Fitness. We were simply looking for something healthy and positive to get our 14-year-old out of the house once a week, a change of routine that would support both his physical health and his mindset. What we’ve received has far exceeded that. From the very beginning, the intake process was thoughtful, thorough, and incredibly welcoming. Danny clearly cares deeply about his clients and his team, and it shows in how intentionally he pairs each person with the right trainer. Ryan has been phenomenal with our son. The fact that he can get a teenage boy to show up engaged, work hard, and genuinely look forward to training each week says everything about his character and skill. The communication, scheduling, and follow-up have been seamless. Danny and Ryan consistently check in with authentic curiosity and care, something that doesn’t always happen once you’re “signed up.” Our son has found a new confidence and passion for getting stronger, and we couldn’t be more thankful for the impact this has had so far. Highly recommend!!!

Ive been seeing Danny on and off since 2017. I had a surgery that limits my movement and of all the personal trainers I’ve seen, Danny has been the most understanding about how I can move. I started seeing him again in 2024 because I’ve been struggling with my balance, and k can say seein him consistently 2 times a week definitely helped me achieve my goals and improve my balance and lower body strength. He definitely takes into account what kind of exercises you find fun and enjoyable and tries to incorporate that into the routine he builds for you. 10/10 would recommend if you’re looking to improve or begin your fitness journey!

I have been working with Josh since September. He has been nothing but amazing! Since starting with him, I have lost 20 lbs, gotten way stronger, cardio improved immensely. He exceeded my expectations. He knows how to set the right parameters, has the knowledge and experience to set you on the right path for your goals.

“Danny is an amazing trainer. As a doctor of physical therapy, I do not hesitate to refer anyone to him who is now pain free from therapy and requires a great trainer to progress them in their fitness goals. He is attentive and always keeps the client’s goals in mind. Could not recommend Danny enough!"
