Customer Testimonial:

As a former collegiate athlete, I kind of lost touch with my fitness and was ready to get back into the grind. I wanted to get a personal trainer. It was one of the best decisions I ever made. The nZone put me with Matt L. and I couldn’t be happier. He is a true professional and has really dedicated his life to getting others in shape. He knows exactly what he is doing and is very patient in making sure you understand all the exercises. His workouts are innovative, challenging, and customized for the areas I want to work on most. He is an excellent motivator and will push you further than you ever thought you could go. Never in my life have I looked forward to going to the gym more. The results after two months are crazy! and I cannot wait to sign up for more sessions with him. If you are looking to get in shape fast and improve your well being, Matt L. is the man to see! -Shaun

My name is Donny Smith and I am the new Football, Strength & Fitness Specialist here at The nZone. I grew up in Sterling, VA and was a former Park View Patriot. While at Park View, I was a two-sport, All-State athlete as a heavyweight wrestler and offensive guard for Football. I continued my playing career at West Virginia University. While at West Virginia, we won the Big East Championship twice, the Sugar Bowl Championship, the Gator Bowl Championship, and the Fiesta Bowl Championship. After three seasons, I transferred to James Madison University to finish my playing career.

In the 2008 season, we were nationally ranked for 12 straight weeks and capped off the year with a CAA Football Championship. While at JMU, I played in multiple games and started 10 in my playing career. During my last two years at JMU, I interned full-time with our Olympic Sports Strength Coach (men’s basketball, women’s basketball, women’s soccer, men’s soccer, cheerleading, baseball, and track) in the weight room and then interned full-time at Bridgewater College with all sports.

Once my playing career was over, I immediately started working in the JMU football weight room with swimming, diving, men’s golf, women’s golf, women’s lacrosse, and field hockey. I graduated from James Madison with a degree in Kinesiology. Upon Graduation, I took a position as a Graduate Assistant Strength Coach at Wagner College. I assisted with football, women’s water polo, women’s soccer, swimming, men’s track, baseball, women’s lacrosse, and women’s swimming. I worked primarily with men’s basketball, women’s basketball, and men’s lacrosse. After one year at Wagner, I took a position as an Assistant Strength Coach at James Madison University. I assisted with women’s lacrosse, field hockey and football, and worked primarily with women’s golf, men’s golf and women’s swimming and diving. I moved to UNC Charlotte to take the Assistant Strength Coach position was personally responsible for the baseball team.  I also built a Division 1 football team from the ground up.

During my coaching career, I coached a multitude of players who later became professional athletes in the NFL, MLB, and European Basketball Leagues. On top of coaching professional athletes, I’ve coached two Olympians for women’s swimming and field hockey. On top of my coaching duties, I trained Arthur Moats (Steelers/Bills), Dorian Brooks (Steelers) and Earl Watford (Cardinals) for the NFL Combine.

Now at The nZone, I look forward to sharing my knowledge and experience with youth and adults of all fitness levels and abilities.

I have always been interested in health and fitness. It wasn’t until I found myself overweight, out of shape and dealing with a back injury that I made a commitment to make a permanent lifestyle change in the form of diet and exercise. I set a personal goal to learn as much as possible about healthy eating and different forms of exercise. I would love to share that knowledge with you.

As a mom of two school age children I understand the challenges of juggling schedules and trying to make time for a healthy lifestyle. I have learned that by setting specific, measurable, and attainable goals anything is possible. My goal as a trainer is to motivate, educate, and inspire individuals to take charge of their health, fitness, and general well-being while they move towards making permanent lifestyle changes. Understanding that no one person is the same, I focus on making workouts challenging, yet fun for people of all ages and fitness levels. Have a dream, believe in the dream, and go after the dream!
