I’m Kevin Duffy. I am the founder and head coach of RPS.
I opened Rotational Power Strength in November of 2020 in Acton, Massachusetts and recently opened our second location in July of 2025 in Natick, Massachusetts.
Our main goal at RPS is to do the simple things savagely well for uncommon results. Our primary focus is to keep each of our client’s accountable for the goals they set for themselves upon entering our facility. Through our training programs, we help them make progress to achieve those goals. The personalized accountability is accomplished through private and semi-private training sessions. The smaller training groups allow each coach to get to know you and help you to accomplish these goals as safely and efficiently as possible.
My Approach
What began as a passion project has evolved into something more. We’re proud of where we’ve been and even more excited for what’s ahead. What sets us apart isn’t just our process—it’s the intention behind it. We take time to understand, explore, and create with purpose at every turn.
Simple ideas
Through every step, we've focused on staying true to our values and making space for thoughtful, lasting work.
Lasting impact
We build with clarity, act with integrity, and always stay curious.
