Optimize Fitness & Performance


Coline McKenna, Competitive Equestrian

As a life long competitive equestrian, I always understood the value of fitness and regular, correct exercises for the horses that I ride and compete, but it wasn’t until I reached middle age that I understood how much it could help my own riding skills and performance.

I have worked with Personal Trainers for the last five years, but a change in circumstances brought me to Devin Gray in July 2013. Devin designed a progressive, always changing training program for me using kettlebells, bands and weighted medicine balls that has helped my competitive riding immensely!My training program with Devin has not only made me stronger, but it has enhanced my endurance, my body alignment, my balance on the horse and allows my legs, arms and core to work independently from each other which is key to riding horses correctly.Even my riding coach has noticed the difference in my fitness, strength and posture. My horses currently live out of state so I am not able to practice on my horses regularly, Devins program allows me to meet my horses at the competitions and walk in the show ring with a strong body and the confidence to compete.

And as an added bonus, I received a “keep it up, your numbers are looking great” from my personal physician at my annual physical in November.

Note: Shortly after writing this testimonial, Coline went on to win several events in Florida – even while competing against significantly younger athletes.


Sarah Purdon, Wheaton College Lacrosse (NEWMAC Champions 2013-2014)

The thing I appreciate most about Devin is the ample amount of time and effort he puts into my plans and goals. I have had results that have completely changed my athletic career for the better. In less than 3 months he was able to fix an ongoing injury I have had for over 4 years. I have yet to re-injure my hip and my overall mobility, balance, flexibility, nutrition, etc. is better than ever. I can honestly say I have yet to be disappointed with a session, workout, or any other element of Devin’s work with me. My results are unbelievable and I only wish I started earlier!

I was recently told by a doctor that the training I did with Devin most likely saved me from a season ending injury. … As an athlete this is one of the most important aspects of training. I could not ask for more out of a personal trainer or thank him enough for getting me ready for college lacrosse, and most importantly, improving my overall athletic performance.

I started training with Devin Gray in October, 2011. In the time that I’ve been training with him, he has taken several classes and received multiple certifications that I have benefited from. He is always changing my workouts to achieve maximum results. He knows how to push hard but also when I’ve reached my limit.

I have never felt stronger and better about myself. I look forward to my workouts because I always feel like I’ve accomplished something. Devin continually encourages me to meet my ultimate goal and I have no doubt that I will eventually get there. Devin is an amazing personal trainer and I would highly recommend him.


Garrett Dishman, Texas A&M Rugby Club

I’ve lost about 10 lbs since starting, and literally receive compliments everyday. Ive noticed a huge difference and even my rugby coach said I look a lot fitter. We just had our first game of the season and I outperformed my own expectations and the coaches said I looked real good out there. I even got my first try, the equivalent of a touchdown. And this all thanks to you.


Terry Niemi

It is a pleasure to recommend Devin Gray. He has proven invaluable to me in adjusting to some challenging medical issues. He took the time to call my doctor and research my medical problems and then developed a custom fitness program that worked for me. He is both knowledgeable and personable – qualities that are not often found in all personal trainers. I highly recommend Devin Gray if you want a customized and skilled work-out plan.
