John Leo Post

John is a long time CrossFitter and adventure athlete who passionately believes functional fitness is key to a positive and healthy lifestyle. John places high values on the community aspect of CrossFit and its ability to make elite training accessible to individuals at all levels. His goal is to inspire others to create positive change in their lives and in the lives of those around them.

John is best known in the CrossFit community as a competitor and member of the winning team, the Modern Gypsies, on ABC television’s adventure series Expedition Impossible. He holds a CrossFit L1 Certification, CrossFit Olympic Lifting Trainer Certification, CrossFit Movement and Mobility Trainer Certification, and has completed Carl Paoli’s FreeStyle Connection Seminar.

Before coming to San Francisco CrossFit, John trained with CJ Martin of CrossFit Invictus and two time games competitor Shana Alverson of CrossFit East Decatur. John has worked with Dr. Craig N. Piso, PhD and Dr. Mark A. Lowry, Ph.D., learning the keys to understanding and practicing mental toughness and teamwork and has trained with professional adventure racers and mountaineers.

John grew up surfing on Pensacola Beach FL and fell in love with adventure sports at an early age. In 2006 while attending Florida State University he discovered CrossFit in the back room of the local climbing gym. After graduating with a degree in International Business, John spent four years living, traveling, volunteering and adventuring through over 30 countries. He was probably the first, and possibly the only, person to ever CrossFit in Cambodia. John returned to the United States to train with his team for Expedition Impossible and pursue his career as a strength and conditioning coach and athlete.

In addition to being a San Francisco CrossFit Coach, John also works with the Modern Gypsies to complete philanthropic projects in developing countries.
