Doug’s Story

For over 20 years, I’ve been training clients across the USA, from Chicago and Miami to Philadelphia and Washington, DC. After years of working in health clubs and for other personal training companies, I started DSM Fitness in 1999. I believed that a more customized, functional, challenging, and yet personal approach to training would yield much better results. I still follow that philosophy today.

I’ve been based out of Washington, DC since 2003, after running two successful personal training businesses in Chicago and Miami. 

DC Personal Trainer - Doug Murphy

My Personal Training Mission

As a personal trainer, I’ve seen clients from ages 9 to 92 (see testimonials) accomplish things they never thought possible. We don’t all have the genetics of a supermodel or star athlete, but everyone can improve on what they have and reach their full potential.

My mission as a personal trainer in Washington, DC is to educate my clients about exercise, diet, and maintaining a healthy lifestyle, while empowering them to make the most of their abilities to reach their goals.

Are you ready to get in the best shape of your life?

I provide the tools to accomplish your goals, through progressively challenging and invigorating workouts. I believe in variety, constantly changing and evolving exercise routines to ensure continual progress and alleviate boredom.


Five years as a fitness instructor at various health clubs during college led to local bodybuilding competition and fitness modeling. After a brief period in the field of commercial fitness equipment sales, I returned to what I had a real passion for-helping people reach their fitness goals, and changing their lives in the process.

What they say about Doug’s Work

Four years ago, I was thirty years old with the back problems of someone twice my age. A sedentary writing job in the least ergonomic chair in the country didn’t help. Stress (and sympathy eating) around the birth of my first child didn’t help either. When it came to food, I was the most “sympathetic” father-to-be on the planet. I was in pain all the time and honestly wondering how I was ever going to be a fully functioning father once my kid could actually walk on two feet. I went to chiropractors but found them to be little more than a sink hole of money. This is where Doug Murphy permanently changed the trajectory of my life. I needed emergency help to drop the weight, strengthen my core, increase flexibility, and end the daily physical pain that was affecting the quality of my life on every front. It was an absolute necessity. Over the last four years, I’ve dropped 40 pounds, and been able to do far more things professionally. But even more importantly, the pain has stopped. Back pain just isn’t part of my daily routine anymore and for that, I owe Doug Murphy a tremendous debt.

For years, I have struggled every day to remain active in my career and socially, despite having to contend with an atypical form of arthritis that attacked my shoulder joints, wrists, hands, and occasionally knees. About a year ago, I began working with Doug to strengthen my weakened and painful joints and to increase my stamina. Before I began to work with him, fear of further injury had prevented my exercising. Doug has guided me in a highly sensitive, patient, intelligent, flexible, and careful way to produce benefits that far exceeded my expectations. In fact, the last time I saw my rheumatologist, he was both surprised and impressed with the striking improvements in my joints, particularly my shoulders. I highly recommend Doug to anyone who has suffered from conditions similar to my own, and who has been afraid to initiate or restart an exercise program.

When I first met Doug eight weeks ago, I was out of shape and my energy level was at an all time low. Basically, I thought I would learn the basics about a good workout routine, as well as gather some facts about my nutritional habits. Well, I got that and more. After an intense eight week session, Doug helped me gain 1” in size on both arms and legs while correcting the muscle imbalances on both sides of my body. I gained 5lbs of muscle and reduced my body fat from 13.7% to 11.7%, while improving my strength. I continue to use all of his techniques during my own workouts. If you are seeking a good personal trainer to help you transform your body, then Doug is your man.

I have been working with Doug for a little over a year and I have been very pleased with my results. Because I have permanent nerve and strength deficits from a long-ago car accident, I needed to find a trainer who knew how to work with someone with special physical needs. Doug has been wonderful- he constantly pushes me to improve, but not outside my capabilities. Since Doug has been training me, I am in the best shape of my adult life. I lost weight and have dropped sizes. The best part is that when I went shopping last weekend, I felt good about how the clothes fit. Ultimately I felt good about myself!
