JD SILOUETTEEM Coaches, Trainers & Staff

In addition to having played Professional or Collegiate sports at a high level, EM Trainers are certified by the National Association of Sports Medicine, have a degree in kinesiology or other ‘regulated’ sports medicine governing body – not just an ‘internal company generated certification’. We are sports training experts, and we think that means going the extra mile with everything we do. We expect our athletes to give us 110% every day, so we give you the same effort and provide you with qualified, motivated and expert training that gets you better every day!

Here are some of the many qualified EM Coaches and Trainers, that together, help make EM an experience for athletes that is unequalled in the performance training industry.

Because the safety of our athletes is our first concern, EM Trainers are submitted to a background check.
