Fairfax, VA 22031

David S. Nickum is an inspirational fitness professional with over 7 years in the health and wellness industry. What he brings to any workout program is a deep understanding of anatomy, nutrition, and exercise physiology. His programs are unique, innovative, educational, and customized to get the job done quickly. He is a cutting edge professional who builds a program that fits your individualized goals.

Starting out in the field of automotive technology industry, David had a lot of problems with pain in the lower back. This led him to the world of health and wellness. David was tired of getting prescribed pills to address his problems and he knew that physical therapy would only be a short-term fix, so he decided to learn about the human body to fix the problem on his own.

Being a musician has helped David to also apply an artistic approach to health and wellness. He always told me; “exercise is an art just as much as a science”, he was right, every human is different and needs an artistic touch to get the most out of a workout.

Throughout his career, David has developed a deep understanding about the human body. He started out only knowing the basics. Seven years later he has become a leader in the field of fitness, he designed his own style of training which works on posture, metabolism, pain management, and performance.

After working with David my life has never been better, the pain in my body is gone for the first time in 10 years. After only 6 months of training I feel like a new person. I feel and look the best I have in years. He gave me the education and the tools I needed to prevent failure in the future. He gave me a new lease on life and I am thankful for that everyday.

    David has been working with my anti-exercise 79 year old mother for three months now. We selected David because of his background in senior fitness, corrective exercise, nutrition and message therapy. He works with my mom two times a week on increasing strength that was lost during a year of chemo and radiation therapy. He is also working to strengthen her core to support a very bad back.

    David is very, very patient but firm with his reluctant client. There has been a noticeable improvement in her strength and eating habits.

    David has turned out to be a perfect trainer for my mother.

    I have been working out with David for about six months now. I am in my mid-forties and have gained over 20 pounds in the last few years. I have a very busy schedule, which only made it more difficult to manage my weight gain and fitness.

    In just a few months, I have gained noticeable amount of strength and endurance and am on a slow and steady path of weight loss as well.

    David’s unique combination of strengths is his ability to train and manage after-workout soreness and pain very well, leaving me enthusiastic to continue to increase my workout level. He is also a very patient instructor and is perceptive enough to increase the pace of the workout based on the trainee’s ability.

    I highly recommend David!

    David is amazing - He's the perfect mix of tough and encouraging, and can help people from a varying range of fitness levels.

    Not only does he come up with amazing workouts that leave me sore for most of the week - he also knows how to deal with different injuries. So, not only can he bring pain but also take it away. This therefore leads to him working you hard !!! That being said, he knows when something painful can be rolled/stretched out rather than just worked around. A couple times when I complained of pain, he rolled out the tight spots and to my amazement, I immediately had a better range of motion.

    He lets me have my overall fitness goals and my occasional superficial goals without any judgment.

    David is one of the best personal trainer I've ever encountered. He's funny, warm , approachable, demanding, rigorous and really knows his stuff..

    If you are looking for a trainer that is not intimidating but still pushes you to succeed David is your answer.

    David's training is the reason I am able to workout and get healthy again. I have fibromyalgia (which is bad enough in itself), but I also fell a couple years ago and badly damaged both feet. The damage in one foot is likely permanent. As those who have had an injury that impedes mobility can tell you, when you're immobile for a long time it doesn't just affect your injured body part, your whole body becomes weak. After my injury even walking up a hill was incredibly hard. I tried working out with 3 trainers before David and 1 when his and my schedule didn't match up. All 4 of them resulted in a horrible fibromyalgia flare up the next day or foot pain so bad I couldn't walk. With David I am getting an incredibly challenging workout that is building my strength without sending me into a fibro flare or foot pain the next day. I may be workout sore (as is to be expected), but no fibro pain. I've built up strength and am starting to feel normal again. I know I wouldn't have been able to work out on my own because I couldn't figure out what combination of exercises I could do without one health challenge or another causing problems. What David is able to do with people who have disabilities or health challenges is truly an art. I am exceptionally grateful to have found him and feel like I am getting my health back thanks to him.

    I've worked with David in the past. He is very knowledgeable and easy to work with. I highly recommend him for any type of fitness goal you may have.
