GBC is a place where you not only learn the correct workouts for yourself, you also learn the proper way to eat to maintain your healthy body weight! The owner and fitness instructor cares and wants to see his customers rise and tackle exercises that they once thought were, “undoable!” He cares and he truly want to see you, “Go Beyond Comfort, to achieve what you once thought was unachievable.” GBC Grrrr!! ?

I’ve been weight training for 20 years with multiple trainers from all of the best fitness centers, but Cornell is by far the best. The location is not convenient for me because I live and work in Mill Valley, but the drive is well worth it. Cornell is masterful at showing you how to connect your mind with your body to achieve optimal results. He is also amazingly fit himself - a real inspiration - and one of my favorite people.
