Fitness visionary, Johnny Goldberg, also known as Johnny G, is the creator of Spinning®, the indoor cycling workout sensation. Born in Johannesburg, South Africa, Johnny was already an accomplished cyclist, competitive swimmer, triathlete and martial artist when he developed Spinning and the Johnny G Spinner®—the first indoor cycling bicycle in 1989—while he was preparing for the Race Across America (RAAM). He opened the first Spin Centre in 1990 in Santa Monica, as well as the Spinning World headquarters in 1994—since then, Spinning has evolved into a global fitness phenomenon. In 2008, Johnny partnered with Matrix Fitness Systems to develop a revolutionary upper-body stationary cycle: the Krankcycle®, and transformed conventional thinking by creating a new genre for cardiovascular training with Kranking®. He currently resides in Santa Barbara, Calif., with his wife, Jodi, and their three children, and continues to explore the possibilities of health and well-being with new and innovative products and ideas.
