Kenneth Yates

Kenneth “Kenny” Yates is one of Northern Virginia’s premier athletic trainers. With over 15 years of experience in the sports and fitness industry, Kenny has been blessed to turn a love and a passion into a profession Not only was Kenny a player of multiple sports, he has also participated as a coach for youth basketball and football, with a record of winning youth titles in both sports. Not only has Kenny played a multitude of sports himself, but he has also shaped the lives of young athletes by coaching basketball and football and helping athletes excel in their game through personal and team training.  Kenny has a proven track record of helping athletes further their capabilities and exceeds their counterparts in the game of baseball, football, field hockey, and lacrosse.

In the past 4 years of his career, Kenny has taken his passion and leadership skills and carved himself a very unique, niche position in the training profession, concentrating his efforts on women’s field hockey and lacrosse.

With his training experience and skills, and knowledge of sports performance and injury prevention, Kenny has quickly become the trainer that parents and athletes alike call when they are serious about taking their game to the next level and beyond.  Kenny has developed a strength and conditioning program that not only prepares his clients for their sports season but also primes the athletes for playing at the “next level”; (making their high school team, their varsity team, preparing for recruiting tournaments or preparing to attend college team). Athletic strength training is the core of his training because “Everyone has an athlete in them. I’ve been around some amazing athletes, but we all have the ability to be better and it’s my job to maximize that potential.”

While Kenny believes that no trainer gets an athlete to college, he does firmly believe in providing athletes with not just the physical tools but also the mental jewels needed to play at the next level.  Kenny has been able to do this with several of his field hockey and lacrosse athletes who are now attending colleges and universities such as University of Louisville, Ohio State University, Appalachian State, Yale, Harvard, Arizona State, Oregon, Rutgers, South Carolina, Brown, Fresno State and Christopher Newport to name a few.

Body Tempering

While frequently working out your body is likely to start to stiffen up. There are a few things to be done.  Stretching, foam rolling, and now here at The Fieldhouse, you have the option of body tempering.

Body Tempering was developed Donnie Thompson, by the first man to power-lift 3,000 lbs, and taught directly to The Fieldhouse’s own Donny Smith.  It is used in some professional football weight rooms and with a number of powerlifters across the globe.

But what is body tempering and what does it do? says “Simply put, the X-Wife diffuses (Dispersal) tissue and its crushing weight relieves tightness involving fascia, muscle, veins, organs, and nerves. They aid in ridding toxins (toxins are strongly acidic, metabolic waste and molecules associated with inflammation but not limited to) specifically from the fascia, veins and nerve encasements. Like a rolling pin kneading dough.”  Muscle and Fitness did a great write up here:

"I started going to Donny after a chronic injury to my hamstring almost sidelined my marathon training. As an endurance athlete, I have always had significant fitness, but not a lot of strength. Knowing my goal was to rehab my injury and increase my performance, Donny put together a plan that included both strength and flexibility conditioning. I am happy to say I was able to train for, and complete my marathon without injury and even ran my personal best of 3:18. I am much stronger now than I ever have been, and will 100% continue to use strength and flexibility conditioning as part of my training moving forward. Although I dreaded the ex-wife, she was good to me and I highly recommend adding body tempering into your fitness routine." – Karin 

"Over the course of almost 2 years working with Donny, I saw my major lift numbers increase drastically. He started by building a solid foundation of fitness and then worked on the form to make sure I was lifting safety. Once that foundation was built, we added load and I saw my bench press increase from 195 to 255 in less than a year, Squat went from 265 to 315, and my deadlift increase from 365 to 415.  The movements varied in a way to keep it interesting so I was never bored.  An utmost professional and I look forward to seeing where I go in the future." – Dennis
