I’m a strength coach helping people of all ages and abilities build lasting strength through personalized programming and expert coaching.

I’m Jack, a strength coach and personal trainer based in MetroWest Boston. I work with clients of all ages and abilities, specializing in individualized programming that produces measurable results.

My approach starts with listening. Every client has different goals, limitations, and preferences, so I build a customized training plan that fits your lifestyle - not the other way around. Whether you're a high school athlete looking to level up, someone in your 50s building strength for the first time, recovering from an injury, or simply ready to feel more capable, I create programming that evolves with your needs.

I work with everyone from young athletes to older adults, including clients with complex training profiles and anyone serious about building real strength. My philosophy is straightforward: progressive overload, solid technique, and sustainable habits that carry far beyond the gym. If you want real structure, real progress, and a coach who knows what they're doing, let's work together to achieve your goals.
