Personal Trainer

Justin Killeen, M.S.

Early in 2012, I was driving around Amherst, Hadley, and Northampton looking for local gyms that may be hiring. I was a (relatively) experienced trainer, recent UMass graduate, and circumstances led me to stay in the area longer than I originally anticipated.
I came across a small gym called “Energia Studios”, nestled in next to Hillside Pizza on Route 9. To be quite honest, I think it was because I was getting a slice of pizza for lunch that day. I was intrigued by it, but each time I returned (not for pizza!), the lights were out and the door was locked. Finally, frustrated, I left my resume taped to the door.
Several weeks later, I got a call back, interviewed, and was hired as the personal trainer. I began two other jobs as well. Eventually, I decided that none of it seemed right for me. On a whim, I started “Pioneer Valley Fitness”, what was a mobile or on-site personal training business. I began to really grow as a personal trainer, working with dozens of people out of their homes and workplaces, emphasizing functional movement and injury prevention. Concurrently, I trained the other half of my time at Energia, as I began to get to know and truly embrace the clientele. It was the one job I just couldn’t leave.
Finally, the opportunity presented itself for me to become Spin certified.
From there, it seems as if the rest is history! In that time, I’ve completed my Master’s degree, purchased and and worked to re-brand the first studio, while recently opening our second location, “50/50 Fitness/Nutrition”. I can, without a doubt, say that none of it would have been possible without some truly amazing people who have been there to help and support me from day one. This new brand really embodies our shared vision for the future, and I’m extremely excited to be given the opportunity to present it to you.
So, with all that being said, welcome to the community!
