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

Health Coaching

Sebastian and the Greens

Want a diet-style that gives you more energy, less bodyfat and less disease? Let's do this.

I'm a certified Health Coach and Fitness Nutrition Specialist. I'm dedicated to using the latest scientific research to provide quality nutritional guidance that changes you from the inside out.

To begin, fill out a food and health journal for one week. We'll use this as a baseline and to make the program completely specific to you.

Sessions are then held online (via FaceTime or Zoom) and done in a series of 4 or 8 weeks:

  • Initial Session: 55 minutes
  • Weekly Follow-Up Sessions: 30 minutes

Health & Nutrition Coaching

  • $95 Single Session, 55 minutes
  • $245 Four-Week Program (Initial Session + 3 Follow-Ups)
  • $445 Eight-Week Program (Initial Session + 7 Follow-Ups)

Corporate and Group Presentations

  • $245 Single Session (90 minutes, on-location [SF], unlimited group size)

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.
