As we head into the 4th of July weekend (when hopefully TeamRWB members can relax and enjoy some beach or staycation reading), we thought you’d enjoy an excerpt from Learning to Breathe Fire: The Rise of CrossFit and the Primal Future of Fitness, by J.C. Herz  a book about CrossFit’s spirit and ethos and the biological and spiritual role of physical intensity in our lives. This excerpt about the kinship between CrossFit and the military has been warmly received by veterans from Fort Bragg to Camp Leatherneck. For folks interested in reading more, books purchased through this link will benefit TeamRWB.org, and Fire has a lively community of military and civilian CrossFitters on Facebook.
