U.S. Navy SEAL training flows into mainstream fitness

By Dorene Internicola NEW YORK (Reuters) – Training for U.S. Navy SEALs, the special operations force, follows a warrior tradition that harkens back to Samurais, but fitness experts say the tough regime is gaining popularity with entrepreneurs, corporate executives, lawyers and elite athletes. "We look at training as being as important to our life as eating and sleeping," said retired Navy SEAL commander and fitness instructor Mark Divine, the author of "8 Weeks to SEALFIT: a Navy Seal's Guide to Unconventional Training for Physical and Mental Toughness." SEALFIT draws on the varied, high-intensity interval training of CrossFit, Olympic weightlifting, plyometrics, powerlifting, gymnastics, calisthenics, strongman exercises, yoga, and martial arts.
