The ISOPHIT™ Strength Trainer is the most valuable and versatile tool we use in helping people improve their function and fitness in the safest and most efficient way possible.  

"If there were Nobel prizes for trainers, Mark Shafer, would get it. He's the best in his field. Mark personalizes my work-outs and regularly refines what we do. He considers my health needs and is always willing to speak to my doctor. I am a committed slug and somehow, someway, Mark gets me through every session. Simply put, there's no one better."

Louie Dweck

"Having worked with Mark and Alex for a number of years, I can tell you that I wouldn’t trust my (aging) body to anyone else. Their background puts them head and shoulders above just about any trainer out there. They make a thorough assessment of your current ability and fitness level, and progress you from there. Their workouts are extremely customized, varied, and challenging without being risky for you. Their training allows them to uncover muscle imbalances that may cause recurrent injuries (like tennis elbow, in my case.) They can then correct the imbalance through specific exercises which ends the cycle of repetitive injuries. I haven’t been bothered with tennis elbow since I started working with Mark many years ago. And my shoulder hasn’t bothered me in several years. My serve is strong, I can run down drop shots and lobs easily and can play for hours without fatigue. I hope to be as active as possible and play tennis for a long time. I stay with EOM because they have the skills and commitment to insure that I do."

"I began going to a specialist several years ago following a severe spinal cord injury, and found that it worked extremely well for me. After moving to DC in March of 2009 I began looking for a new specialist in the area, and luckily found Mark. He was a pleasure to work with--not only do I leave each session feeling increasingly better, but they are knowledgeable, friendly, and able to take the mystery out of the process to get better. Their ability to clearly and completely explain exactly what it is that they are doing and why leaves me feeling that I have a good understanding of my process of recovery and where each session fits in to the plan. They are fun, friendly, and very dedicated to helping me recover, and I know from my conversations with other clients that I am not the only one that feels this way. I would recommend Mark and his team to anyone who is in need help with joint and muscle problems."

"Being a professional athlete you must go through vigorous training that may really break the body down. Before going to Elements of Motion, my shoulder range of motion was compromised from over use and a former shoulder surgery. I was also experiencing severe knee pain. After a few sessions with Mark, I had increased range of motion in my shoulder and the pain in my knee had subsided. With that increase in range of motion, I had an increase in strength and power which are key elements to my volleyball game. Element of Motion helped me get back on track with my intense training regimen that is needed as a professional volleyball player."

"I was referred to Elements of Motion after I injured my Achilles Tendon but waited three years before requesting a consultation. In those three years, I tried everything from repeated rounds of physical therapy, acupuncture, yoga, and visits with a orthopedic surgeon. After all those treatments and thousands of dollars, I was still not able to do so many of the activities that made me happy. I had gone from being an active person who logged more than 30 miles a week running to someone who complained constantly of discomfort, tightness and pain in my calves. I began to give up hope that I would be able to run or jump without fear of re-injuring myself. After just a few weeks at Elements of Motion, I felt an improvement and was able to ease myself back into a running routine. I'm now back to running three times a week, have completed two 5K's and have not experienced the tightness and discomfort that had plagued me for the three years after my injury. My only regret is not going to EoM sooner!"
