Personal training at Optimize Fitness & Performance is the best way to achieve your health & fitness goals. Lose weight with mindful eating and real food, instead of supplements, shakes, and restrictive diets. Our gym is welcoming and laid back. We work out hard (and smart), but you won't find any yelling, screaming, or "hardcore" workouts here.

Other trainers are $80-100 per hour and have less experience and education than our coaches. You'll receive an in-depth assessment, individualized workouts, and personal training from our experienced coaches. I want to help you get into great shape. More importantly, I want to help you get better at doing whatever it is you love to do most.

I'm Devin Gray, the founder, and I'll be honest - I didn't like what I'd experienced working, or working out in, other personal training gyms in the area. I saw too many trainers whom weren't nationally certified or didn't bother to properly assess their clients. I saw too many avoidable injuries caused by trainers who were more focused on being trendy than on getting results.
We pack in as much information as we can, as many of our members like to read and research before contacting us. If you'd rather save some valuable time, we recommend reserving a free phone consultation with head coach Devin Gray, CSCS. Step 4 - Get 100% free advice from Devin, with specific, actionable steps so that you see progress right away.
I'm an award-winning personal trainer with over 7 years of experience and 10,000+ sessions coached. My goal is to help you "optimize" your physical fitness through strength training and scientific training methods. I've dedicated the last 5 years to making Optimize Fitness & Performance all about delivering great fitness results.
Instead of 1 on 1 sessions, which are cost-prohibitive, we offer semi-private coaching sessions throughout the day. It's not small group training - it's a more affordable, more effective method of personal training. Never miss a workout - You have up to 30 days to make up any missed sessions, for any reason, without cancellation fees.
Good news, everyone! Optimize Fitness & Performance was awarded a spot on Thumbtack's "Best of 2015" award list. We're honored to be the only personal trainer in Franklin to be selected for this award. In our opinion, most people are paying way too much for personal training. Even worse, many of them pay too much to work with an inexperienced, under-educated personal trainer.

Devin has been a great PT expert getting me to focus on trouble areas plus dealing with 51 years of accidents and bad form. He is patient and knows how to work with you to get back to your new normal.

I hired Devin to help me get in shape to ski for the first time in 25 years. When I started working with him 2 months before the trip, he put together a workout plan for me to do in his gym, as well workouts customized for me to do at the fitness center I have access to at work. He modified exercises based on how I was doing, what I liked doing (and didn't like) and my abilities. In his gym, sessions included anywhere from 1-4 of us, each with an individual plan, and Devin was there to oversee those the workouts.
When I finally hit the slopes in Colorado, I had the strength, and therefore confidence

Devin was incredible in getting me started with lifting. Professional, patient, and extremely knowledgeable. As someone who had barely lifted before, he covered all the basics and fixed any form issues I had. I only worked with Devin for a few months, however, he gave me countless exercises and techniques I am still using to this day. He followed up numerous times with me to check on my progress, and even sent over additional exercises I could look into doing. If you are on the fence about taking some lessons, go for it!

I started at optimize fitness a little before the pandemic and was worried about not being able to enter the gym. I transitioned to online and have to say it has worked out great! I took pictures of what I had to work with and Devin customized workouts to my equipment and to a prior back injury I have had. Great communication right threw the app or text messages. I cant wait to get back in the gym with him and his positive attitude! I highly recommend him and his gym!

I came to Devin because I wanted to start getting stronger and I had no idea how to get started. I appreciated that Devin took the time to listen to my goals and help me think about achievements, like developing my first push up, dip and pull up. I was impressed by his evaluation of my current status and how he could tell that I’ve previously had foot issues.
What was great was how he developed a plan that let me train myself at my local gym without his supervision. He has of course always provided great feedback and answered any questions I’ve had along the way. He also celebrated when I

I have worked with several personal trainer/fitness coaches over the years and by far Devin is the most impressive. He addressed my concerns over increasing arthritic knee pain and deteriorating overall strength by tailoring workouts I can do both at the Optimize studio 2x week and on my own at home. I couldn't be happier with the results.

I started working on with Devin in the fall of 2019 after a series of injuries from playing basketball, biking and weekend warrior activities. My goal was to get stronger to prevent the injuries that I was getting while being active. I went to his gym 2x a week and within a few months started seeing and feeling results.
Devin did a great job of assessing my strengths and weaknesses both before I started my program and during. The focus was on form and working around my injuries to start which I greatly appreciated. I've managed to work up now to more advanced weight and exercises and am feeling

I initially came to see Devin due to longstanding knee pain that was not responding to PT. I have now been at Optimize Fitness for two years. Devin is an expert at both fitness and nutrition. He has not only helped me exercise pain free by showing me exercises that are suitable for my knee, but he has helped me gain muscle and improve my overall strength. Devin is motivating and positive. I highly recommend him if you want a customized experience to meet your goals!

So what do you do when your about to turn 5o and your already falling apart!?! You carefully fix what you can and see if you can find a very patient person to help you on your journey back to fitness and a healthier life.
I found Devin in March of this year (2016) and went to meet with him about how I could transition from Physical Therapy (Rotator Cuff injury) to a fitness program that was actually tailored to my recovery and rebuilding. I wanted someone who would take their time but most of all help me to find the love of fitness again. No easy task.
It's been 8 months and I don't know what
