Wylie Belasik, Owner and Coach

 Wylie comes from a background in non-profit and sport activism, having promoted sport  and active lifestyles as a tool for social change across the country.

“God, Drugs and Loving Myself”

In 2008, I was entering information from a survey that I had given an individual who was experiencing homelessness in Philadelphia.  The survey was a simple one and on it, the final question was ‘Please list three factors that you believe contributed to your state of homelessness’.

The response was clear and heart-breaking.  The man had written, ‘God, drugs and loving myself’. It struck me that the individuals who we are most often trying to help are not unclear on their needs or situation. We are hard-wired to want to be proud, strong and contributing to the fullest extent of our capacity. However, sometimes, circumstances intervene, our lives shift and we lose sight of what we can offer to each other.

I believe in sport as a tool for social change. I believe that when we sweat and push ourselves, we see who we are meant to be and can share that with others. That’s the root of a healthy community and what I’ve spent the past 10 years of my life building.

Morgan Vozobule, Coach and Head Coach for Liberty Barbell Club

"I came across CrossFit late 2011, bored with my solo-gym routine and struggling daily with self motivation. Shortly after joining, I knew I had made the right decision. It soon became my priority to become a part of the community that CrossFit Center City had built: inspiring, encouraging, and awe-worthy. The importance of my own performance gains were soon paralleled by the progress of fellow athletes in the gym, and I wanted to be a part of them doing well. Coaching has given me a front row seat to watching people change their lives for the better, challenge themselves daily, and do more than they had previously thought themselves capable of."

I love watching people transition from beginners to athletes. I believe in people before they believe in themselves and I think that helps them commit to our style of training. I also design the programming for our Intro to Olympic Lifting program and competitive Olympic Lifting Club, Liberty Barbell Club, which helps members build a foundation for excelling at the technical lifts.

Luis Salazar, Coach

Luis found CrossFit in 2014 and it has been a love affair ever since.  Luis began his fitness journey working at Jefferson Hospital where he is still employed as a Clinical Coordinator in GI and Liver Transplant.  Back in 2010, there was a weight loss challenge and at 320 pounds, Luis knew he needed to change his life.

After shedding weight by simply walking, then jogging, then running, then participating in the Broad Street Run(x6)and the Philadelphia half-marathon(x2), Luis realized the benefits of living a healthy active lifestyle.

CrossFit gave Luis a place to not only get strong, but to feel strong and accepted in such a special community.  As a Level 1 CrossFit coach, Luis' transformation has come full circle.  As someone who made the journey from a sedentary lifestyle to CrossFit coach, Luis uses his experience to relate to athletes at every level of fitness. "Dream big.  Sparkle more.  Shine bright!"

Jesse Dawson, durABLE Coach

Growing up, Jesse fell in love with sports. He was always interested  in trying any new sport and played organized basketball, football, baseball and tennis. This was were he learned that committing to practice the fundamentals was the only way to improve. He realized at a young age that an expert at anything was also once a beginner.

Watching ESPN in 2009 was when Jesse was first exposed to CrossFit and immediately knew he needed to learn more, making it his goal to get a muscle up.

Recently, Jesse began coaching as participant of Subversus’ UliftU program and hasn’t looked back. Since starting his CrossFit journey, Jesse has been inspired by the process of learning different movements and more importantly how to teach them to others.

Arthur McDaniels, CrossFit Coach

In 2006 Arthur came to Philadelphia from Newark, NJ seeking recovery from drug addiction. He entered a recovery program and begin striving toward a new life in a new place. After graduating from an outpatient treatment program, Arthur’s life seemed to be on the right track, but then a few years later, he found himself back in the homeless shelter system. It was during that time, he learned about Subversus’ program, UliftU and the opportunity to learn how to become a coach in the fitness industry.

As someone who always worked out and loving to help people he knew this was his future. After completing the UliftU program, Arthur now coaches at Subversus and you’ll see his smile behind the front desk. Arthur also coaches free fitness classes in North Philadelphia, three nights a week for those at risk of chronic disease at no cost.

“That is the most fulfilling part of what I do. I look forward to doing more in the community. ULIFTU and coaching has changed my life for the better. I am on a continuous course of personal development. A career path that allows me to help others do the same. I am loving this life.”
