About Jonathan

Over the years, I have amassed a great knowledge for exactly how to do that and the interpersonal perspective to help unique individuals change their lives in lasting ways.

My goal is to help my athletes (clients, or whatever name you prefer) maximize what they value and improve their ability to realize and express those things to their utmost in life. 

My favorite client story

While working at a Sports Performance, I became friends with an athlete who was planning to transfer from Stonehill to Notre Dame in effort to walk onto their D1 Football team. After getting to know each other, hearing my input, and implementing my advice, he asked me to program for him and be his coach. Given his work ethic, I could not say no, despite my lack of specific knowledge. Since then, I empowered myself to be able to coach for Football specific training and he has made the team and begun to surpass some of his competition!

My favorite exercise

Olympic Weightlifting (Snatch, Clean, and Jerk) and Handstands!

My favorite quote

Don't fear failure. Not failure, but low aim, is the crime. In great attempts it is glorious even to fail.

My training philosophy

We get what we put into it. I design my training sessions to not only give a good workout but to educate my athletes (yes, you) to be able to 1) Live life with greater health, 2) Replicate the movements we did on their own with sufficient technique and intensity for growth, and with enough time together 3) Have a solid understanding of what works, what does not work, why, and where they can most improve what they value - whether that be physical functioning, physical appearance, or general (mental & physical) health.
