Get Real Fit.

I train outdoors near Dolores Park in San Francisco and in my clients' homes. Sessions are held Monday-Saturday, 6am-1pm. Please contact me if you need additional training times or live outside SF.

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.
