Get Real Fit.

I train outdoors near Dolores Park in San Francisco and in my clients' homes. Sessions are held Monday-Saturday.

Training with me you will notice increased energy and confidence, reduced body fat, increased muscle tone, greatly improved cardiovascular fitness, and a body that is more balanced, capable and athletic. I offer a no-fads, no-gimmicks approach for people who want real fitness.

Sebastian is by far the best trainer I've ever worked with. I never thought I'd call a workout a "treat" but that's exactly what his group sessions are. - Nathalie A.

Group Training


Group sessions are energizing and motivating, while reducing cost. Sessions are 55 minutes and held at Noe/Liberty.

Semi-Private Small Group Sessions are 2-6 people and booked in advance. The limited group size means you will not get lost in a crowd and I can plan a top notch workout that matches you. $50. Schedule

After doing in-depth research on trainers in the SF area, it was clear that Sebastian was the top pick. And it's true - he's amazing and we couldn't be happier. - Allison C.
