Real Testimonials and photos from real clients

Leah J.

I had a “cheap” gym membership.  I had the knowledge of what to do with the equipment in that gym.  I may have set foot in that gym 10 times in the past year.  You see, at “that” gym, I was a faceless number, a person who paid my dues.  No one cared if I showed up at “that” gym. 

I was desperately seeking a better, healthier life, but I didn’t have the desire or the will-power to do it alone.  I wasn’t sure what to expect when I first called Core Fitness Nashville and made an appointment with Dustin.  I gave him and his routine a try.  Then I committed to show up and make an effort to follow his instructions.  Dustin plans a different, challenging, achievable routine each day.  He makes nutritional suggestions.  He is encouraging and motivating – in a positive way.  He walks the talk.  He listens to you and he molds routines to fit your special needs.  Dustin is educated and knowledgeable in the subject matter of healthy fitness and nutritious eating.  I never dread a workout at Core Fitness Nashville, nor do I ever leave there disappointed or feel like it was a waste of time.  I am pleased to announce that in just 6 weeks of following Dustin’s routine, I have lost 10 pounds and over 10 inches.  I plan to keep tweaking to get the best “me” I can be!  AND, I cancelled my membership at “that” gym.  I found the best workout in town…at Core Fitness Nashville!

I started with Core Fitness Nashville around Christmas time of 2013. I needed something with a variety of times and wanted something with a personal training feel. I travel for work every week and needed to have options. I love that the gym feels like a group of family and friends getting together to keep their life healthy and fit. The small intimate group classes is exactly what I need to stay focused and get my burn on at the same time. With the smaller group classes I feel that he is able to assist and challenge me throughout each session. 
Since starting with Core and Coach Del Rio I have lost 15lbs and dropped from 27% body fat to 16.6%. I couldn't have done it without the support and guidance of Core Fitness and Coach Del Rio. Dustin set up workout plans for me to do on the road and also helped guide me with my nutritional needs and meal plans. It's hard to eat healthy at home let alone on the road, but he has give me guidance and materials needed to make it happen. Core Fitness gives us all the tools we need to be successful in our healthy lifestyle…there are NO excuses here! 
At over 40 years of age, I am in the absolute best shape of my life. With training from Coach Del Rio and support of other clients we even competed a Tough Mudder Competition, something I never thought I would ever do. Dustin isn't afraid to get in there and get dirty with his clients. That's one of the thing that makes Core Fitness a very unique Gym.

I always looked forward to having children, but I was also afraid (more like utterly terrified!) of what the pregnancy would do to my body. Once I had my 8 month old son last December I was determined to get my body back in shape so I could be the wife and mommy I always wanted to be. 

I could not have accomplished my goal if it weren't for Dustin at Core Fitness! His gym is simple and effective. I love doing exercises that get results without the hassle of working with some complex, intimidating machine. The workouts are fun, challenging, and exciting so much that I never got bored! Dustin is an awesome trainer because he's energetic, compassionate, and tough in the gym, but he also goes the extra mile and provides you with recipes, articles, and personal challenges to maintain your physical fitness outside the gym as well.

To all the moms or soon-to-be moms, take my advice: you will be a better person and mother if you take some time for yourself by working out and keeping yourself in shape. As a result, I am confident, healthier, toned, and stronger than I ever thought I would be! Every time I get a compliment for how in shape I look after just having a baby, I can't help but think, "Thank God for Dustin Del Rio and Core Fitness!"

Dustin Del Rio's program at Core Fitness has changed my life. I had 2 children, a demanding job and my body was not keeping pace. Through Dustin's Personal Training, his energy, positive encouragement and no excuses approach, I now am strong, lean and so proud. I am more fit than i have ever been in my life- at 35!! The workouts are my stress buster and a great part of each week.

Core Fitness helped me reach a whole new level in my fitness journey!  As a guy who struggled with weight his entire life, I finally made the decision to change in 2008.  I weighed over 350 lbs. and my diet consisted of every drive thru in town.  After working hard with various trainers and dieticians, I achieved my goal weight of a healthy 220lbs.  My job changed in late 2012 and I began to compromise on my eating choices and workout commitments.  By fall of 2013, I had completely abandoned my healthier way of life.  A doctor’s appointment revealed a weight of 285 lbs.  It was a wake-up call.  Core Fitness answered the call.  I met Dustin and began with Core Fitness in the fall of 2013, but quickly had to take a two month break to attend to some personal situations.  I promised to start after the holidays—and did just that.  The day after Christmas, I began a regimen with Dustin and have not looked back.  I have lost 60lbs and am back in my goal weight range.  During my initial workout assessment, I struggled to perform assisted pull ups—and now can hammer out 10 unassisted!  The journey has not been easy, but I feel like I have had great support along the way.  My job demands quite a bit of travel and Core Fitness offers a variety of options to insure that I get my workouts in on the days when I’m in town.  The personal training sessions have proven very effective for me—challenging but fun.  The group sessions add variety to my workouts and offers peer support of like-minded people.  I’m pleased to say that my size 42 pants have been donated and I’m now in 36’s that are loose.  I appreciate the friendship, sense of community, and support received from Core Fitness.  Dustin’s guidance and support have enabled me to reach and sustain my fitness goals—and I’ve made a few new friends along the way.

I've never stuck to a workout plan or even enjoyed it before, but this is fun, challenging and movaties me to be better. Trainer, Dustin DelRio puts together a different work out routine for each session and I always feel like Ive had a total over all body work out. If you want to change your body and your attitude sign up today!


Paula F.-

I love the concept of core and circuit training and both of these apply in this class.  The Trainer is punctual, inspiring, encouraging, persistent,  and motivating in the sessions and growing us to reach our full potential.  He is also always stretching us to do more and be better, and what's more he does it in a way that it's respectful to who we are individually.  Always a great workout and I leave knowing I've worked out every aspect of my body both in burning as well as toning and muscle development.  Love it!


Kimberly S.-

This is by far the best workout I've ever done.  For the first time, I look forward to working out.  At 45, I can honestly say I look and feel better than I did at 25!  The combination of cardio and strength training in circuit format get results FAST!

Kelly C.-

Core Fitness trainer, Dustin Del Rio, provides me with one on one training that I couldn't find anywhere else in Nashville. Instead of trying to lose weight, I needed to gain weight....and I have never looked or felt better in the last 20 years. Every sessions is different and pushes me to do more than I ever knew I could. It's never boring, always entertaining, always intense and I leave knowing I got an awesome workout! Give it a'll be glad you did and your body will thank you for it!


Rhiana P.-

I will be honest, I did not begin my workouts with Dustin very enthusiastically. However, it was time to get back in shape and feel better, stronger. After just a few short months, I really began looking forward to my workouts, missing them even, on days I can't be there. Dustin really knows how to help you get 100% out of every session - not by yelling at you with a no-pain-no-gain attititude, but by encouraging you in a positive and energetic way. The workouts are awesome and I am definitely the strongest I have ever been. The atmosphere is not like any other gym - it is personalized, encouraging, energetic, positive, and upbeat! I highly recommend Dustin and Core Fitness Nashville to everyone!

Christena F.-

I spent years dealing with medical issues and when they were finally over and the Doc gave me the all clear to workout I found myself very much out of shape. Dustin is amazing! He was very patient and designed a program so I could ease back in yet challenged me. Four months later I feel better than I have in over 10 years. I am squatting again and pushing myself to limits I didn't think were possible any longer.
You are a blessing my friend...thanks again for all you do.


Brittini B.-

I love how intense each exercise is but because you break it down and switch it up so much, you don't even realize how many calories you're burning! And don't realize all the muscle groups you're working at the same time. Get in, workout hard, and get out feeling awesome! Core Fitness is the bomb!
