Locations

J+K Studio

The Mission, SF

Training built for you, not a template.

Your desk posture, your old injury, your packed calendar. I design around all of it. Every load tracked, every movement assessed. Progress you can see and feel in how you move, perform, and recover.

About Juan

Built on a life of performance.

I've spent my life pushing my body at the highest levels. Swimming for the Mexican Olympic team. Competing nationally in Taekwondo. Training through university at Tepeyac.

That journey taught me how to perform safely and sustainably, without burning out. Now I help busy professionals build that same foundation, so they can stay strong for life.
